I have never watched a more misleading discussion from Tim Spectre since Zoe was started. He sits there as brown as a berry and says people don't need Vit d supplements in a country that very rarely has sunshine. That sounds hypocritical for those that cant afford multiple foreign holidays eavh year.
Tim can’t be trusted anymore he should Resign!! He’s assuming that people even get out into the Sun😮 There’s evidence in Chronic Illness in particular, that levels of VitD are low & evidence that says how much good levels contribute to fighting Infections, Calcium & Phosphorus absorption (Must take K2 for Calcium restore & maintain Calcium in the Bones) VitD also helps muscles work and nerves to carry messages to the brain & body but most if all, if the body does not have enough VitD, it will take from the bones because Calcium is vital for other crucial mechanisms in the body!
Yep, that was my take on this too. You plebs can't afford all my luxurious holidays and business trips but you mustn't help yourselves by taking something that is cheap and available to you instead hmmn 🤔
@@Lisa-my5sy in theory that's right but it's my understanding that the issue is that these days we spend a lot more time indoors, not getting the sun exposure we used to. Plus when people do spend time in the sun, they put on sunscreen, which can block the body producing vitamin D. Years ago people had more time outdoors because of their work in the fields for example and there was no sunscreen, so they were getting their vitamin D from the sun.
I’m 81 years old and I had a sacral fracture when I was in a car crash. On my six week checkup, the surgeon was amazed at how well I had healed. I take 5,000 iu of vitamin D daily as well as vitamin K2 and will continue to do so! 😁
Continue the combo ma’am. Your bones will look like that of a teenager and your immunity stable. Loads of rubbish trying to deter people from taking these
Absolutely incredible we’ve just sat through two medical professionals discussing vitamin D, calcium, bone health and arterial calcification for an hour without mentioning the role of K2. Also no mention of magnesium. Referencing caveman studies with no regard for the synergy between multiple vitamins and minerals, if only it were so simple. 😅
You probably need to listen to the functional medicine-trained doctors to get an understanding of the synergistic and complementary effects of nutrients.
@@tifqureshi3895 Absolutely. Their expensive 'personalized' diet which measures the tiniest fluctuations of glucose levels as if that is significant is a great money maker but not a reliable contribution to information on the gut biome. I don't know why I watched this except to wince. And it's dangerous if it influences people to stop taking Vit D (which is a hormone, not a 'type of steroid') we all could go on and on .... sigh.
A few thoughts on this interview... Jonathan's interview with Dr Federica Amati and Dr Tim Spector is quite interesting, but in some cases it is not conclusive and some important aspects were not covered. I also got the impression that the views were a bit entrenched, statements were made cautiously and sometimes seemed fearful. What was positive was that both experts consider vitamin D to be important for humans. In addition, they tended to see additional calcium supplementation via food supplements as harmful unless prescribed by a doctor. Calcium is sufficiently absorbed through vegetables, fruit and dairy products. Both experts therefore regard vitamin D (steroid hormone) as important, but are of the opinion that 400-800 iu daily is sufficient, and also refer to sun and food, although it is known in practice that sun exposure is perceived to be too low and food is naturally not sufficient. This does not fit together. No adult can get out of a deficiency with the dosage mentioned, unless one is satisfied with vitamin D levels of approx. 18-24 ng/ml. (Studies show, for example, that good bone metabolism only takes place above 30 ng/ml). The topic ‘What is a good vitamin D level?’ was not addressed at all. Consciously? The most important cofactor, magnesium, was also not discussed. Question from Jonathan to Federica: ‘Can you be vitamin D deficient without experiencing any symptoms?’ Answer from Federica: ‘Unlikely.’ Frederica probably doesn't realise that vitamin D deficiency often leads to silent and insidious symptoms that people pay little attention to or don't even notice, even though they are present. Over time, these symptoms then develop into complaints and become clearly noticeable, painful, etc. Many doctors can misinterpret these symptoms. Examples: muscular problems, hair loss, unexplained tiredness, exhaustion, low spirits, depressive moods, concentration problems, skin and nail problems, more frequent viral infections, poorer wound healing, to name but a few. The negative influence on our bone system anyway... The influence on cancer, diabetes, cardiovascular and autoimmune diseases too. There are also studies of all three that show the connection between poor levels and diseases. Or the positive influence of good levels on a variety of diseases such as cancer and autoimmune diseases. Federica talks about the cofactor vitamin K (but means K2) and the indication that vitamin K (K2) is formed in the intestine. However, the possibility of converting K1 (!) into K2 is reserved for only a few people, and only if they have the right bacterial strains and an excellent gut. In my view, some of the statements were incorrect, inadequate or contradictory, especially the missing aspects about a good vitamin D level. Greetings from Germany.
@@Celticspy911 Thank you... Yes, but fortunately the interview did not also include calcifediol (calcidiol). Then Tim and Federica would probably have had to endure even more negative criticism.
@@Fitundgesund100 Very good points, and helpful. I also had nagging doubts as to the possible bias in their interview. I have listened to numerous professors talking about the benefits of vitamin D3 + K2 It seemed like they were using circular reasoning to keep coming back to diet and fruits and veggies. As ZOE is a business, you would have to address the motives. Please check this out for more information. th-cam.com/video/uyUoK71uATU/w-d-xo.htmlsi=dL9SKJDeWcj8dhTI
Is this the same VITAL trial that chose people where the majority already had Vitamin D levels at 30ng/mL, gave those 2000IU a day, but all participants (including the placebo group) were allowed to keep taking 800IU a day (if they were already), and then didn't find much difference between the two groups? Yes, it was a stellar trial, almost like it was designed to show no benefits. A few other points, whilst common in the US, dairy is rarely fortified with D in the UK. Mushrooms have to have Sun exposure to create any D, so check the label. The best food, oily fish, typically has about 500IU per portion, so just enough to prevent rickets. Other foods have significantly less. Vegetarians/Vegans will have great difficulty getting any meaningful amounts of D from their diets. Vitamin D takes weeks to be metabolised into a useful form where immune health is concerned (basically, you will not see an immediate benefit) and then much longer to be stored as a reservoir in fatty tissue where it can be drawn upon when we lose the higher Sun. It then has a half life of about 60 days. In the UK, the Sun is too low in the sky for about half the year to provide any significant D through UVB, so 3x60 day periods. I'm sure you can do the maths and work out what that means for your levels by Christmas and beyond. You can get 10,000 to 20,000 IU for about 20 minutes full Sun exposure during midday in the Summer, and yet there is fear-mongering here about taking a few thousand IUs in a supplement everyday? Too much paracetamol is toxic, too much Vitamin D is toxic, and guess what, too much water is toxic. If you really are worried about toxicity, get a blood test before supplementing, then re-test 3 months later. Different people do metabolise D at different rates, and there are many factors that influence this, so don't assume that if you friend is taking X amount of vitamin D, and their levels are 30ng/mL after 3 months, yours would be the same. There is so much really important information missing from this podcast about D, it's quite demoralising.
Totally agree. I don’t remember a Zoe podcast with so much criticism in the comments. They really need to start including citations to the studies they mention.
Completely agree and the VITAL study shows a 20% decrease in the risk of developing autoimmune disease which is so significant given the pandemic of autoimmune disease. So disappointed with this podecast.
I would highly appreciate the references to the studies snd clinical trials mentioned so I can go through them and make sn informed decision. Is it possible ZOE?
Totally agree with you, There was a lot of scary nonsense about overdosing without any mention of eating fermented cabbage. I thought Zoe would be all over that 😠
I’ve started questioning everything, especially government health advice! After reading "Health and Beauty Mastery" by Julian Bannett, I completely changed my habits. This book reveals so many shocking truths about the health industry!
@meditim2032, can I check how you came to find the book by Dr. Julia bannett? I guess what I am asking is how truthful the book is, too????? Seems everything these days is for money.
I am more inclined to believe the interview with John Campbell and Dr David Grimes. Dosage depends on weight, colour of skin. The older you are as skin dries and does not absorb as well from sunlight. I had blood test and was insufficient. Took supplements according to my weight and after another test I had sufficient. You would have to take huge amounts to be harmful. No money gain from Dr Grimes but a life time of study, knowledge and research.
Yes, and disappointingly Tim Spector seems to be referencing bone health and metabolism as the be all and end all of vitamin D needs, when others argue that's the tip of of the iceberg in terms of needs .. I'd like to hear a far more nuanced debate that accepts this, evolutionary levels and immune system requirements rather than simply backing up NICE recommendations .. the inference that Campbell and Grimes are both influencers and influenced by the supplements industry is also very disappointing.
@@bruceanderson1044 Campbell is a massive grifter now. But his vit D videos were made before he 'turned', and he was right about vitamin D. He pretty much backed up everything my respiratory consultant said (good vit D levels are essential in asthmatics)
Reverse causation is also well documented, meaning that illness lowers vitamin D levels rather than low vitamin D causing the illness. In the same way blood levels of cholesterol are lower when people get sick so high levels are not necessarily a sign of good health.
@@rickduker4969 Low vitamin D is a result of modern lifestyle. We know that most people are low vitamin D without having to look at reverse causation. You can bet your boots that most of those people would have had low vitamin D irrelevant of illness.
In the interests of balance, for anyone new to this topic, I was diagnosed by a leading endocrinologist at Addenbrooke’s Hospital with Vitamin D deficiency - the 25OH test measured me at 8 nmol/l compared to the expected normal of > 50 nmol/l - even though I walk and cycle thousands of miles every year, eat a healthy diet, and are trim and fit (BMI of 20.0). I’m mixed race and live in the UK. I presented with many symptoms including muscle fatigue and body aches. I was put on a high dose of Vit D3 initially (40,000 IUs per week), stayed on this for a few months and have since supplemented with around 5,000-10,000 IUs per week. Most of us don’t have the luxury of being able to measure our VitD levels, so maintaining a preventative level of supplementation seems sensible. My symptoms have not returned. Key message from this podcast is that everyone is different, so educate yourself, try and get yourself professionally tested and if you have any of the key symptoms then take a modest supplement, otherwise do nothing.
I had almost the same experience, doc put me on 40,000 iu per week to start me off, I was fine within 2 weeks. I also happen to live in a hot country, it shouldn't have happened, but it did. My pharmacist was telling me that since Covid, there's been a huge increase in people being prescribed vitamin D3.
My daughter who was in her teens had huge vitamin D deficiency. Was put on a high dose for a couple of months to get her levels up. She was exhausted all the time, ate well and loved sunshine. I wish testing was an automatic health check. She now takes 5,000 ius which is right for her weight.
i have very similar experience. I am from south of Europe, moved to Finland (~15 y ago) and at that time nobody told me I should get vitamin D supplements, and the only dose available was 5ug!! After a few years I have developed different symptoms, and no doctor could help me until I figured out it was vit D deficiency- at that time "normal" base here was 10x lower than nowadays, but I read work of dr. Stasha Gominak and followed her advice, supplementing with enough does of vitamin D (had to order from abroad), and B-complex. Within 6 months (winter time) my symptoms were gone and nowadays I regularly supplement and also my children to stay healthy and strong! It is too bad that we must be own doctors because idiot doctors don't understand that over here where I live we don't get correct wavelength of Sun from August until Jun! In addition, summer over here doesn't do much for me due to my darker skin, so I must travel south. I have never burned my skin in my life, but I do gradually expose my skin to build up the tan.
I interviewed Prof Michael Holick when I was university studying clinical nutrition 15 years ago. Even back then, he was saying that the 50 nmol/l was too low and that it should be 100 nmol/l.
I was also waiting all the way through for them to mention vitamin K2 - especially when the topic of calcium came up - and particularly as K2 is found in fermented foods which are good for the microbiome
Yes, if you are in a group that doesn't get enough sunlight (us night shift people included) or were specifically recommended to take vitamin D due to deficiency, then yes, you probably should supplement.
@@newdawnfades263 I also think that patients that are in hospital for more than a few days may need supplements, for the same reasons. Modern hospitals often have very little sunlight, little to no windows and little access to green outside space. ITU and ICU patients particularly can be at risk of low Vit D levels and have no access to infrared light.👋🏻 from a nurse in Germany
Michael Mosley did a podcast on why vitamin D was one of the only supplements he recommended. How is anyone supposed to make an informed decision on this?
@@gruber1650 Spector says a lot of good stuff about diet but also has a habit of basically trying to say everything is wrong apart from his on gut health theories. Yet the evidence basis for this is always quite tricky to pin down. He’s competing for a limited slice of the self-help/supplementation market. Profit is his main objective.
Science is a process. It is the best method of trying to understand the world. As we gather more evidence, the conclusions become firmer. You can choose not to believe in the scientific method, but any other form of understanding the world is infinitely worse. Tim himself stated that he is open to changing his mind on vitamin D if the evidence supports it. He is a mark of a good scientist. I myself have been taking 4000 IU of vit. D a day and after watching this video, I'm going to markedly reduce it. You might decide a different course or action. This here is the gray area, which science embraces. This is the nature of the universe, us incrementally understanding it, sometimes one foot forward, two feet back, sometimes two feet forward, one foot back. Stay healthy.
I find that Tim Spector likes to find something which lots of other scientists/Doctors like and then trash it! I do watch these things and also have some of their books and found that each book has points in it that are different from the earlier ones and a genuine statement of “I got it wrong” however, your right how are we supposed to judge what’s right or wrong. Basically a little of everything and not too much of anything will probably do us all fine 🤔😃👍
These questions are very complex and there is ongoing research so probably no final definite answers to them yet. How else are we making any judgments if not based on actual scientific research?! Just opinions and/or manipulations for profit's sake.
Absolutely? Really? You've got good science to back up that assertion? And a good case to say that taking supplements of any description is better than having the healthy diet and lifestyle which Zoe have been advocating for years? Really? Could you point us to the studies supporting your view.
I listened to this entire video and decided that I will continue taking my D3 and K2 supplements as Dr John Campbell suggested. Sadly I have lost trust in the Zoe health advice. I think Tim Spector is also wrong about unprocessed red meat and animal fats.
Use Google's NotebookLM with the Audio Overview feature. It can turn audio, video (including youtube), and text sources into a 10 minute AI hosted podcast that is very convincing. Free feature.
yes, Tim Spector seems not to know that it D is crucial in the metabolism of neurotransmitters., So, It does not matter if vit D causes mental health problems or not. What matters is that low vit D makes it more difficult for doctors like me to treat mental health problems.
I'm in my late 60s and live on the west side of the UK. I walk my dog daily but I no longer wear bikinis or crop tops and seldom wear shorts or short sleeved T- shirts, certainly not in the winter. Even on the beach, in winter, the dog walkers are wearing wellies and wind proofs. We don't all live in care homes, but still wrap up. That with our declining ability to synthesise VitD means I supplement.
The same could be said about people wasting money on Tim Spector's "Daily 30" mixed seed supplement which works out at a staggering £120 per kg, when people can easily purchase a selection of mixed seeds themselves for a fraction of the cost! We all know that eating more plants is good for us and therefore we don't need to waste loads of money on Tim's seed supplements and books to do this!! He is simply raking in 💷💷💷 from very clever marketing. You can actually buy a year's worth of vitamin D for about £5, which isn't really breaking the bank for most people.
Well said! What a misleading video this is .... yeah lets all expose ourselve to the Sun and get skin cancer. Most of us need Vitamin D supplementation, especially in the Winter. What is happening to Zoe? It is steadily going down the pan since Steven Bartlett came on board .
@@ratmanbugIt doesn't matter how long you're outside for if the sun is low in the sky, like it is in the UK between October and March. It is literally impossible to synthesise any meaningful amount of vitamin D in the skin when the sun is 45 degrees or lower in the sky because the thickness of Earth's atmosphere at that angle filters out UVB radiation. Rule of thumb, if your shadow is longer than you are tall you're not making vitamin D. This October to March window is even longer for people with darker skin tones.
The sun needs to be at a 45° or higher angle in the sky to be strong enough to make vitamin D - otherwise too much of the necessary UV component is blocked by the atmosphere.
I was severely deplete of vitamin D and had lots of bad symptoms. Taking vitamin d has definitely helped me, first thing I’ve ever taken that I actually felt a difference. I’ll stick with it and can’t be bothered watching all of this video, too much conflicting info.
If you'd stuck with it, you'd have heard them say that some people do indeed need supplements, like you, but the vast majority of us will be better off taking a walk in the afternoon and eating a few specific foods.
If you had bothered to watch the video you would have heard them say many times that the small fraction of the population who present with your symptoms benefit from taking vit D supplements.
Rather disillusioned by this podcast that might well put me off Zoe in the long run. So much more info about the beneficial effects of Vit D on the immune system out there with research to back it up especially with reference to flu, chest infections (apologies no link) and really, are we still banging on only about its effects on bones? That's so well known and documented and has been for many decades. Move on. Stick to the microbiome studies, Tim.
Quite agree. The main area that Tim Specture seems to be behind the huge amount of research. Living here in Cumbria we are getting almost zero natural VitD.
so it prevents MS and helps in inflammatory diseases like Chron's and cancer but only people in these sub groups should take it? Surely there is a continuum of benefit and therefore makes sense to supplement it if only as a potential preventative measure - agree that it is very complex but not convinced at all by the arguments here.
They ‘forgot’ to mention the VITAL randomised control trial showed 2000IUs of vitamin D per day reduce the risk of developing autoimmune disease by 20%. So if everyone took 2000IUs a day of vitamin D the NHS would save so much money given the explosion in autoimmune disease. This whole podcast was absolutely rubbish as most comments indicate.
If a person has the money to waste on tablets, I guess? But good food and activity is far more beneficial. But that approach doesn't make money for supplement companies.
@@mariarotaru2069 despite overly enthusiastic headlines, actual risk reduction was just 2.5 cases out of 1,000. Hundreds of people would need to take vitamin D daily for years to prevent a single case of autoimmune disease. Vitamin D can interact with other medicines, and taking high amounts of vitamin D can be harmful.
With no first hand experience, but having read a fair amount of literature, there seems a clear overlap between the defined symptoms of vit D3 toxicity with magnesium deficiency (hypomagnesia) as well as K2 deficiency in relation vit D3 ratio (hyper-calcification)
Agreed you need to take very very high amounts (we are talking tens of thousands of units on a frequent basis for an adult) to get intoxicated, it is possible and it is very dangerous but it is extremely rare. The boxes containing such doses have warnings and guidance about not taking them daily but every week or once a month for example.
A few years ago, I went for a blood test The doctor said that my vitamin D was low, so she helped me supplement vitamin D. After taking it, I started to have many problems. First of all, I started to become depressed, anxious, have high cholesterol, high blood lipids, and xanthoma on my eyelids. I had no idea where it was. This is a problem because I am a person who eats very healthily and exercises. I just found out today that vitamin D is responsible. It’s terrible. Now that I stopped taking vitamin D, the xanthomas on my eyelids stopped growing. But in order to find out the truth, I took it again, and xanthoma began to grow on my eyelids, and I started to become irritable. Also constipated.
I respectfully disagree with their position. There are hundreds of research papers that demonstrate the benefits of Vitamin D supplementation. For these supplements to be effective and yield evidence-based results, the dosage must be appropriately tailored to each individual. This is likely the reason they believe it isn't effective.
They didn't say no supplements, they said supplement if you're not getting 400 to 800 IUs daily. BTW, the US endocrinology association no longer recommends vit D supplements either.
@@robmcguckin7605let s verify if US endocrinologist association does not recommend anymore supplement of vitamin D3 , because that on its own would be a bombshell !!
@@spiral-m "According to the latest guidelines from the Endocrine Society, they do not recommend routine vitamin D supplementation for healthy adults under the age of 75." Your turn.
For Tim Spector's information,I had a skin condition on my fingers and toe.The nail bed had been destroyed.Hospital hadn't a clue and recommended an operation.One doc thought it might be the immune system but didn't know how to improve it. I started on Vit D after watching Dr Eric Berg.The skin problems completely cured after a few weeks.I also very rarely get colds,flu anymore.Take it with K2, and magnesium/zinc. I am still waiting for my referral from the NHS..Now over 4 years.
I never have colds anymore since taking daily vitamin D3. I'm quite shocked by Tim Spector's illogIcal advices. Getting vitamin D from sunshine in winter in the UK, really??? The notion itself is ridiculous. Then the advertisements for ZOE courses show they're basically a grift. Tim Spector is the chief of ZOE.
My only gripe with Zoe is they quote scientific studies but fail to include them in the references or link followers to these studies. They also don't give enough information for followers to find these studies themselves. Give us details so we can read plz I get it that this is a podcast rather than a scientific essay or lab report but for those that are studying science or have already become a scientist it would be really valuable informstion, and it could also mean we coukd critique some of whats said on Zoe. Win win for everyone because we all learn, and Zoe is held to account for any possible shody experiments
Hey... my replies are not showing up... but to finally reply... Tim has been incorrect many times (search youtube 'calorie counting doesnt work' or 'exercise doesn't work', and see people explaining it). And he's always talking outside his field, you never know when he's wrong, and can often be.... hoping this comment goes through. :/ I prefer the episodes where the scientists are speaking about their field of study.
@martinbulmer1868 sadly most people are more pleased with themselves criticising than with really listening or looking into things. Zoe try really hard to give good advice. Of course this doesn't mean they know everything, or can always get the best of the best on the show. But I'd rather see their moderate content than the evangelising you see elsewhere. If people transcribed their content and then checked their criticism against it, they'd see much of it is a premeditated reaction to personalities or ideas they have a negative emotional response to, and not actually a valid argumentative response.
@@Raherin I guess it's cheaper than paying others. Plus if you listen, he does cite a lot of involvement in studies related to vit D. I can't imagine vit D specialists grow on trees. But, yes. It would always be better if they can find absolute specialists. Those specialists need not to be employed by companies with conflicting interests of course, and many are, as if you sell vit D, you are bound to employ the top experts on it.
Perhaps vitamin D is a thorn in the side of medical "science" with its "studies" mostly paid for by industry because it actually helps to prevent diseases and mitigate disease progression.
Speecter isn't 'medical scince' he's a nutritionist with a fixed set of ideas and a hatred of supplements - 'you just need a healthy diet', but D is the most difficult chemical to get suffiently when unable to make it in skin - whether because living in the north or from age or skin colour. And then there's clickbait, seems to be more youtube than doctor.
26 NHS "Doctors" died of covid - 25 of the 26 dark skinned. But don't join the dot. Meanwhile I haven't had any respiratory infection in 25 years because I learnt about immune enhancement of which D is only one part.
Gotta do something to promote your business, even if your products are low margin. But promoting vitamin d can also help out those who sell blood tests and supplemented foods
I find this show can get guests who haven't spent a lifetime in certain studies going against a lot of research from people who have spent decades specifically in that certain subject.
There didn't seem to be much chat about darker skinned people living further north. Also what happens when we have a poor summer, with little sunshine, relative to a better year?
Also didn't discuss you have to have major parts of your body's skin exposed. Something some cultures discourage. Just having your head/face/hands outside isn't going to cut it!
Tim Spector should call Dr. Anthony Fauci and educate him on why Vitamin D doesn't help with a certain respiratory disease. I think Federica was much more measured and scientific in her presentation. Spector has a completely closed mind on this. That's too bad.
He's the only one I've come across on many, many searches who holds this view so one has to ask why ? When also they are so cheap why not take them providing one is sensible about it. The logic behind it is irrefutable !
Dr John Campbell had a great guest talking about his lifetimes work with vitamin D…Dr Grimes….check his knowledge….and he’s not selling us anything…just his wisdom 😊
My understanding is that it is nearly impossible to make vitamin D in winter months, particularly if you live above 37th parallel, ie above Sicily. This is because the earths atmosphere filters out theUVB which is needed to make vitamin D. Not saying we should take supplements, oily fish , mushrooms etc are great but just clarifying that sunscreen won’t make a difference. I live in Switzerland where sun screen is essential in winter due to UVA. We still won’t make vitamin D in winter without sun screen because there is very little UVB.
I take 5000 ius of vitamin D3 gel capsule per day for the last 5 years. No colds or flu since, however, if I feel I'm getting a cold i increase to 10,000 ius for a few days. Also take K2 as well but some people maybe allergic to that...
I take around 6000 iu a day in the Winter through to around May time, (in Berwick NE). I have noticed a huge difference in my resistance to infection and I've never shied away from the Sun.
Exactly the same, used to get colds etc all the time - been taking vitamin D3, K2, Magnesium etc - and touchwood no colds since pre-covid. Guess though everyone will have a different story on that on.
Watch Dr John Campbell's videos on Vit D and K2, endorsed widely by reputable research and by world-renowned oncologist Professor Dalgleish. Much more convincing than this.
The more I learn from Zoe and my app the more I understand living a natural life with good diet and little walk everyday day will just steer you well generally. Zoe has cured my IBS my poor sleep my poor mood and I enjoy food more. Thanks everyone at Zoe
I cured my IBS by cutting out most plants from my diet. I suspect you might have added more plants. Both of us probably cut out the ultra-processed foods. Maybe that's a great first step.
@@trail.blazer actually, Ive had IBS since I can remember. My diet used to be mostly meat, dairy and eggs when it all started, and for many years after that. Now, Im vegan. I get some months where I am totally fine, but then other periods are horrible. It's like I cant link it to any specific food, cuz on the good months, they dont trigger me at all. It's frustrating. Ive tried fodmaps, probiotics, high protein/fat, high carb, lower fiber, higher fiber. Doesnt seem to change a damn thing.
@@Progressivelyyou I tried all those things. Also a low histamine diet, not that I expected much from that. For me, fiber made it worse. Fiber supplements made it way worse. As I got older, the fiber was more of a problem. So, I started reducing the fiber. It was a leap of faith to almost completely cut out the fiber. How could I possibly poop?! Then the IBS symptoms stopped. I still eat a little fiber but really not much. Maybe up to 4 grams on a high day. Haven't had any IBS issues for years. And I poop great.
Let's just add in all the other vitamins, minerals, and other nutrients while we are at it for proper balance 😅 there's a reason no one can make these types of nutrition videos without taking flak from random people on the internet. You really can't cover everything in one subject, one video.
I agree, we can't all get a suntan like Tim. It doesn't make sense, Dr Amati says can't get enough through food but you shouldn't take a supplement? I can't go in the sun so have to take supplement, I was taking g 8000iu and my blood levels were only 75nmol/l where 50-100 is normal so don't think the amount of supplements recommended is enough, I take mine with lots of Kimchi for vit K2, it stinks.
I had mild psoriasis for years and also had low Vitamin D. When I started taking Vit D supplements it went in a few days. I went on holiday for a week and forgot the jar, and the psoriasis came back. When I came home I resumed the Vit D and it went again.
The problem with the research is that it is over simplified and there are more variables involved to see results. First, vitamin d supplement is only one chemical. In the body, vitamin d analogs are sunlight (UVB spectrum) between 11am to 1pm "activates" the starting process on the skin. Also, secondary vitamins super important, K2 A and Magnesium. The vitamin d improves calcium uptake, so getting k2 is super important to manage calcium. If not sufficient secondary vitamins then calcium becomes a problem. To increase bone strength, start with the signal. Jumping rope twice a week, rebounder, vibration plates, and simply jumping up and send the signal from brain to bones. Next, increase magnesium to much higher doses. Phosphorous in foods will increase parathyroid hormones and thus reduce mineral in bone. So phosphorous shouldn't go over 350 per day. Also include boron in diet. Last ingredient is lots of time. Those following this protocol will not have weak problems.
wouldn't it.....!? I think he wouldn't only be out of his lane but he'd get run over.... Dr Grimes was an actual practising clinician seeing real patients.
I quite agree. Dr Grimes also said older people or anyone with dry skin can’t convert Vit D from sunlight because they don’t produce the skin oil that’s required for the conversion. Dr Grimes recommended 1,000 IU’s per 10Kg body weight daily. He takes the equivalent of 8,000 IU’s daily in a single dose each week.
Tim keeps talking about fractures, most do not disagree on this. We should be focussing on the effects of supplementaion and the effetcs on the immune system. Particularly, studies when people are taking sufficient dosages and getting their blood levels up above a certain level.
Agree. Dr Berg knows a whole lot more on this d3 subject. Except he always insists on taking d3PLUS K2. Spector makes no mention of K2 or magnesium. They all work together.
Spectre needs to give it a rest! There have been enough studies done that show the effectiveness of vitamin D. I find Spectre boring, to say the least.
A general audience could really do with a an informed, practical, clear summary of why vitamin D is important and what, on the basis of cited studies, they should consider doing about it. This, alas, is not it.
Also saying only take calcium if your doctor prescribes it - surely it would be better to advise some strong questioning of any GP routinely prescribing it for elderly patients as many GPs seem so ignorant of the risks of what they prescribe.
@@DavidSmith-rz1pc we’re talking about one thing - prescribing calcium supplements. There is more than enough evidence now it’s a risk for strokes and heart attacks.
I simply do not trust them because the imperative to sell Zoe seems to be paramount. In addition, a deficiency in vitamin D is measurable. Plus Vitamin D has been shown to reduce the dangerous effects of COVID.
Did you not watch the video? Literally everything you said is addressed and debated. And none of it (except at the end when the presenter talked about Zoe) was used to sell Zoe
Important point that Dr Amati mentioned regarding people of colour (particularly darker skin tones) not always being able to get enough vitamin D from the sun in the Northern hemisphere (even if they spend time in the sun). Some people in the UK also have their skin covered up (apart from face) by clothing even in the summer due to religious and cultural reasons, so are unable to get enough vitamin D from the sun.
Well, I had extreme fatigue and virtually no Vitamin D in my system, a doc prescribed a high dose and after just a few pills I was fine. Since then, I take it periodically when the fatigue creeps back.
Great thought from Tim. Its good to listen to all kind of comments and look who puts the money on the statement. Everybody can be wrong. Im 70 and have seen lot of comments that has changed during the years no matter what professor so its very good to doupt things and make up mind on real studies and to think that people have lived long on this earth. With different lenght of life of course. look at your own body and see its reactioons. Ive never used any kind of creams, i love to be in the forest and ive never burned my skin.. i get brown yes but no burns. Summertime i cover with a cap and think when i need clothes to cover. Never taken supliments or medicine but good food and lot outdoors. We are different in our bodies.
Tim is becoming a broken record - everything is about food variety. I agree that lots of plants and plenty of variety is probably very good advice but when a scientist tells you that spending 5-10 pence per day on a supplement is a waste of money and can be better spent on increasing your diet variety then you know there is some kind of bias in the reporting. At 35 or 70 pence per week you're looking at adding an extra small sprig of broccoli or half an avocado. Tim said our bodies stop accumulating Vitamin D when we have enough from natural source but we can take too many supplements - I'm struggling to understand how the body knows what source the extra Vit D came from - the body can distinguish vitamin D from sunlight and that arriving from a tablet . . .
You don't absorb Vit D directly from the sun. You manufacture it, and your body knows when to shut down the assembly line (assuming you still live in your ancestral environment or one similar to it). But if you take preformed D, then your body can get overwhelmed if you take too much.
I take 10,000 IU per day as a maintenance dose along with Magnesium, Vitamin K2 and Zinc. Did you know if you sit out in the sun during the summer for 20 minutes your body generates 10,000 IU from the sun's rays. Some people spend hours in the sun, think how many IU's that will make. The NHS recommend people take no more than 400 IU a day. WHAT A JOKE.
THE NHS recommends 400 IU a day of Vitamin D which is a joke. If you go out in the sun for 20 minutes in the summer your body generates around 20,000 IU.
Since we're apparently all different on how well Vitamin D is absorbed, it's important to know what your level is. I have been taking 5000iu w/K2 for roughly 3 years and my Vitamin D level is only 46 ng/ml. I probably need to increase my D3 to 10,000iu.
@dreamcaster99 Yes, but your body is in complete control of the vitamin D it makes so it may only use 1000 iu of that 20,000. However, exogenous vitamin D your body doesn't control so it can do harm
I had low mood, anxiety, bodily aches & pains, poor sleep and some psoriasis. The GP suggested it may be a vitamin D deficiency. I initially thought this was strange as I eat a healthy varied diet and take a multivitamin and mineral supplement containing (a ridiculously low level of) vitamin D3. I live in the UK though and only get a few months, at most, of decent sunshine each year.......& I work indoors. Anyway, I added a daily vitamin D3 supplement to my diet and the improvement to my above mentioned symptoms over time was nothing short of spectacular !! This was a very disappointing, and narrow in scope, review of vitamin D by ZOE and I heard little information with much credibility from Tim Spector, frankly. I shall most definitely be continuing to take my daily maintenance dose of 5000iu of D3 throughout the summer and 10,000IU of D3 throughout the winter. In addition to taking K2, Zinc, Magnesium & Omega-3 fish oil ..........which I suspect Tim Spector also feels I don't need and am wasting my money on ..!
Yes but before the modern era, people spent many hours outdoors all year around. Now we are much more sedentary, few people work outdoors all day long. As humans, we are designed to be outdoors a large part of every day. So it's highly unlikely that we have 'enough' vit D - maybe enough to survive and function, but logically, we cannot have ideal levels for our species. There is also the simple fact that the skin has to be exposed to create vit D. It's not going to penetrate jumpers, coats and jeans. So going out in winter in northern Europe is good for a bunch of reasons but it ain't going to give you much vit D when you're exposing at best the face and hands. Totally agree with Tim about sunblock though.
We also need near infrared NIR sunlight because of the benefits to our cellular mitochondria. One reason people get sick in the winter in northern climates is the lack of exposure to NIR. It’s hard to get sunlight on your skin while wearing a parka.
I don't think one should listen to anyone thinking it is the highest and final truth. There are studies on vitamin D3 safety, like "Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial", which did not find any major negative adverse effects from even vitamin D doses up to 10 000 IU/day. While such high doses seems to be safe, most studies on efficacy are done with dosage of few hundred IUs daily, hence they did not succeed to prove efficacy... As always, the "experts" are just messing up with peoples minds using their "higher understanding" and imaginative knowledge.
Most people in the UK don't spend lots of time outdoors ... and even less on days when the sun is shining & they are "sporting lots of bare skin" ... most people will have covered skin, even on the few hot sunny days that the UK experiences
I think this is an unsubtle episode. I would suggest you don't get sunburnt ever if you can help it. I would also suggest it's not possible to get sun exposure regularly in the UK especially if you have an indoor job (perhaps why we then go and get sunburnt it is sunny). I would recommend anyone with health issues takes vit d at the very least in the winter months especially if you start getting joint and muscle pain. Bear in mind that taking high doses of vit d could also lead joint and muscle problems. If you are well, have a good diet and are often outside then yes maybe you don't need a supplement. Skin cancer is still a thing. Last I heard there are more cases in the UK than Australia because we don't take it seriously.
18:40 "the industry has made a disease where none really exists" Is a little bit cynical of Professor Spector tbh. There's sod all money in the production of it as there's no patents or other IP issues so any johnny come lately can get in on the game. On a side note what are there opinions on combining vitamin D with Vitamin K?
I've definitely felt benefits, particularly regarding depression ( 1000iu-5000iu) seems to make a dramatic difference, especially in Northern climates where we get less sun.
I had four different cases of chronic inflammation and low levels of vit D (29). I got on a dose of Detremin that doubled and tripled it, 3 months later all the inflammation ended simultaneously without ANY other changes.
My personal experience is that a small dose of Vitamin D3 when needed lifts my mood. Thinking of this in relationship to S A D (seasonal affective disorder).
I will add my anecdotal experience which I realise many from here will disagree with. I used to be vegetarian and ate lots of seed oils. I would burn in an hour of cycling in New Zealand sun even on a cloudy day, so I always used sunscreen. I have not consumed seed oils for around 5 years and now mostly animal based diet for over 3 years. Since changing to that, I can now go out in full sun (no clouds) for 3 hours with no sunscreen and zero issues. I do sailing and if I'm out on a boat for more than 2 hours then I do use sunscreen. I'm not claiming that I am invincible to burn but it does take much longer. Was it the diet change and removing seed oils? Who knows but it is somewhat unlikely to be much else. Without supplementation and during a summer my last 25 Hydroxy D test was 151nmol/L. I do now supplement 4,000 IU daily during winter. Yes, you can overdo vitamin D supplementation, but you do actually have to do silly things. It is very unlikely anyone taking 5,000 IU a day is going to even get close to issues.
Hi Tail Blazer - Yes I've had the same skin sensitivity change since removing seed oils. I'm blond and I used feel the 'burn' on my skin in 5 mins in UK summer sun, now I will sit for 3 to 4 hours in Spanish sun, then I might add some sun screen, but i find it almost impossible to burn now. I only use vegetable oil to lubricate my chain saw now!!
I am really surprised not to hear any mention of the fact that vitamin D3 needs vitamin K2 and magnesium in order to be able to process vitamin D supplements. I once spoke to a herbal nutritionist who made me promise to take a handful of greens (for the vitamin K2 element), in combination with the liquid vitamin D3 supplement. I know that I my health is very much better having worked outside in the sun than I do in the winter.
When one ages the skin begins to decllne with the necessary cholesteral to synthesize Vitamin D. Also in the winter months taking Vitamin D supplement is imperative. It is really important for older people to take it. I had Osteoporosis and could not tolerate the drug for it. I began strenuous walking, taking 2000 units of Vitamin D, K2M7 and Magnesium. My osteoporosis went away.
I can buy a years supply of Vit D3+K2 for about £6.00 - I don't think many commercial producers will get too rich at that rate... I also notice that the NHS, as stated in my medical record, say that many people benefit from having 50 to 75 nmols/ litre, and that the elderly suffer fewer falls when their levels are 100 nmols/litre ! There is no way I, living in the UK, can get any VIT D from the sun between Oct and March, without either taking supplements, or going to a Tanning Studio (with increased risk if skin cancer)
Your stated values of 50-75 nmol/l are too low, because bone metabolism, for example, only functions properly at levels well above 75 nmol/l, and levels of at least 125 nmol are helpful for the immune system. In autoimmune patients, positive effects of vitamin D are observed when the level is around 175-200 nmol/l.
In Saskatchewan, getting outside in -30 to -40C is not happening for me!! If I go out, I'm wrapped up head to toe with no skin showing. No possible way of getting sun exposure!
Also I did Zoe for 6 months but developed an allergy to being patronised and spoken to as though I were a small dim child and recording all you eat on the terrible app is a full time job unless you fast which is maybe how so many people lose weight on it, they'd rather starve than go through the meal entry process
Just tuned in and haven't finished watching this episode yet, but I have to comment about my own experience. I spend hours in the sun every day, I do not use sunscreen, and yet I am still severely deficient in vitamin D. Blood tests showed my levels of vitamin D were in the single digits. Perhaps I'm just part of that small minority that actually needs supplementation.
People with autoimune issues absorb vitamin D with problems. Like Hashimoto. I was told what others get in 20 minutes for a Hashimoto sufferer can take up to 8 hrs.
Combination with Magnesium helped me absorb the vitamin D either from sunlight during summer time and with supplement (the liquid one with olive oil) the other months. These I could have proved having blood test to check the improvements (I'm now doing it twice a year to check the figures!)
In the nordic countries vitamin D is a must during winter. There is no sun and when there is, we are covered in winter clothes. During winter it's dark when I go to work and dark when I get home (7-15 work day) so there isn't even possibility to go out to enjoy sun for many reasons.
Actually the Rcketts and osteomalacia were seen prior to WW11. The ministry of health saw to it that children got orange juice and cod liver oil and malt. These conditions reemerged in the ethnic populations with dark skin. One of my school friends had Rickets, but that was because she was born in a Japanese prisoner of war camp in Shanghai.
Vitimin D is important for thyroid mechanisms. If all cells in the body have a Vitamin D receptor then they need access to it. If there is only a limited supply available then some areas may not have the access they need. People don’t go out in the sun and if they do they often wear sun screen. Older people very rarely go out in the sun and their bodies do not process food as efficiently. Their immune systems are not as efficient either. For the cost of Vitamin D I will be continuing to take it, get the sun when I can and eat a good diet. I also take magnesium, K2, CoQ10, Complete EFA (Omega 3, 6, & 9) and extra vitamin C & Zinc during winter.
I'm UTTERLY confused! I have worked with a Vitamin D specialist and my whole family is on high doses of D daily for many years. I feel now that I am harming myself and my family. I was told D/K/B’s Omega 3 and magnesium should be taken daily and the combination of those key. My husband reduced his homocysteine levels down to healthy readings by supplementing the recommended doses of the above. I respect Dr. Spector a lot but this talk is missing lots of context in my opinion
Didn’t learn much here…. It’s pretty clear that high vit D ( 60-80 ng/ml) is not a health risk especially if vit K2 levels (microbiome or supp ) are normal..
I've been lately thinking Zoe has been bought out the info lately is wrong. Unfortunately Tim's face is on every days news feed in Australia sent to my phone, that doesn't happen by chance "disinformation" tool.
Good luck living in west of Scotland and being able to get out for 20 mins sunshine every day! Also no mention of the menopause and risks of osteoporosis.
And the dubious benefits and considerable cost of Zoe… Spector is hardly an impartial voice in the “wellness” market given the questionable benefits and considerable cost of poo gazing and glucose monitoring.
They missed the single most important fact about vitamin D - Always take d3 (not d2) with vitamin k2 and magnesium. One more thing - we are what we absorb. So, if you have leaky gut (most do), you won’t absorb the d3 so you need to take more.
I wonder if Tim has ever tried to get his doctor to do a vitamin D blood test? My experience is that it is impossible. Therefore, how are you supposed to know whether you have a low level?
Indeed, how do you know. I badgered my GP, the senior partner, he said he was not allowed to order the test, so he transferred me to a new junior GP. She ordered the test as part of a wellman test, with the comment that the lab might not do it. Strange comment, something else going on I thought. Surprisingly the lab did do it, 170nmol/L, she advised me to stop taking it as I was out of range. I had to tell her the NHS advice was 30 years out of date and was incorrect. She made no comment.
Very strange that all of a sudden they say vit 3 builds up in your body whereas forever they say that's the opposite. In hospitals it's been proved with large doses of vit D and vit c does help recovery, it's the first time I've watched this channel I can stand the interviewers drawl, by the way how rich are Zoe owners ?
"There's no data for that" what a load of BS. What Tim means is " there's not a lot a money going in to research on alternatives to the massive global pharmaceutical corporations and instead a lot of money is absolutely going in to dismissing alternatives to pharmaceuticals...."
Thanks for the show. I'm a ZOE stan :) however, tend to be disappointed how "the scientists" only make mention of us dark-skinned people as an afterthought if at all. In Tim's case, he almost talks like we don't exist in these parts of the world too. It would be nice to see other scientists on your team who are capable of noting those nuances, especially on relevant topics like vitamin D.
Dr John Campbell has discussed with leading scientists the benefits of supplementation of Vitamin D3 (alongside K2 that was not mentioned here). I will continue to take the advice of Dr Campbell on this subject, over and above anything stated here. I'm very disappointed that fact based evidence linked to poorer outcomes for those people with low levels of Vitamin D was not mentioned, such as in the elderly, some ethnic minorities and the obese.
A very disappointing and longwinded podcast! 1. Not much about older people and how older skin can or cannot absorb Vitamin D. 2. Nothing on how other vitamins and minerals affect the uptake of Vitamin D. 3. No information on the many benefits on the immune system. 4. My story: I am 83 and have always led an active outdoors life and had a good varied diet. After age 50 I began to suffer from difficult outbreaks of oral herpes with symptoms, not only of painful coldsores, but also raised temperature, facial neuralgia and aching body that affected badly me for roughly two weeks out of every month. I sought help and after some years I was prescribed preventative antiviral medication to take every day. This helped until I developed serious side effects and had to stop. Ten I lived with these incapacitating herpes outbreaks until a new GP prescribed Vitamin D supplements when I was aged 70. Since then I have not been troubled by oral herpes.
I experienced some osteomalacia a year ago, not a serious case but I was having a lot of muscle and bone pain and various other issues, my GP couldn't figure it out. I started researching it myself and thought I'd try a daily dose of 1000IU of vitamin D3, and wow I felt so much better.
Their research are so outdated. I cannot stop rolling my eyes. I didn’t hear that they even mentioned D3 + K2. How can any reasonable doctor not mention that? They focused on Calcium And D3, which most sensible doctors don’t prescribe anymore. They didn’t mention the effects of D3 for inflammation. Most people are so inflamed and VD is so crucial for their health to lower inflammation risks! stop fixating about fractures and bone health. I am so disappointed Zoe let this happen.
My VitD levels were always borderline critical (low) over various years, and no GP ever suggested supplementing. I also had incredibly low anti-mullerian hormone (linked to fertility). After starting to take Healthspan Vitamin D supplements. My anti-mullerian hormone levels increased significantly, even though I was years older. And I fell pregnant, and the paediatrian that managed my pregnancy was really impressed by my VitD levels (which had significantly increased). So I feel I have evidence that the supplements helped me in a profound way.
As for calcium, he should have explained that it's calcium CARBONATE that is bad to take since it's pretty much just ingesting rocks. The citrate form is way better, but never take more than a couple hundred mg's a day.
The same bad calcium carbonate that is used to fortify almost every plant 'milk' and other food that has 'added calcium'. I'll stick with eating a few fermented dairy products that don't have added calcium. 👍
I have never watched a more misleading discussion from Tim Spectre since Zoe was started. He sits there as brown as a berry and says people don't need Vit d supplements in a country that very rarely has sunshine. That sounds hypocritical for those that cant afford multiple foreign holidays eavh year.
Tim can’t be trusted anymore he should Resign!!
He’s assuming that people even get out into the Sun😮 There’s evidence in Chronic Illness in particular, that levels of VitD are low & evidence that says how much good levels contribute to fighting Infections, Calcium & Phosphorus absorption (Must take K2 for Calcium restore & maintain Calcium in the Bones) VitD also helps muscles work and nerves to carry messages to the brain & body but most if all, if the body does not have enough VitD, it will take from the bones because Calcium is vital for other crucial mechanisms in the body!
@@catrino5453 Just eat better and save your money on supps. She did mention that gut microbes produce vitamin K.
Yep, that was my take on this too. You plebs can't afford all my luxurious holidays and business trips but you mustn't help yourselves by taking something that is cheap and available to you instead hmmn 🤔
Native Brit’s have the skin tone that evolved for the region tho
People living there who aren’t native to the region have different vit D needs
@@Lisa-my5sy in theory that's right but it's my understanding that the issue is that these days we spend a lot more time indoors, not getting the sun exposure we used to. Plus when people do spend time in the sun, they put on sunscreen, which can block the body producing vitamin D. Years ago people had more time outdoors because of their work in the fields for example and there was no sunscreen, so they were getting their vitamin D from the sun.
I’m 81 years old and I had a sacral fracture when I was in a car crash. On my six week checkup, the surgeon was amazed at how well I had healed. I take 5,000 iu of vitamin D daily as well as vitamin K2 and will continue to do so! 😁
Continue the combo ma’am. Your bones will look like that of a teenager and your immunity stable. Loads of rubbish trying to deter people from taking these
@@ISAACOLUSEUN-k3bthe bones of an 81 years old woman will look like the bones of a teen if she carries on taking vitamin d? Seriously, people!!! 🤯
Well said. There is no way I can get enough vitamin D from exposure to sunlight. Scotland just doesn’t have that much sunshine.
That’s over 10 times the recommended amount. Your rapid recovery may have been down to many factors
@@erinneil5480 Exactly!
Absolutely incredible we’ve just sat through two medical professionals discussing vitamin D, calcium, bone health and arterial calcification for an hour without mentioning the role of K2. Also no mention of magnesium. Referencing caveman studies with no regard for the synergy between multiple vitamins and minerals, if only it were so simple. 😅
Doesn’t surprise me in the slightest .. it’s an idiotic channel now
You probably need to listen to the functional medicine-trained doctors to get an understanding of the synergistic and complementary effects of nutrients.
@@tifqureshi3895 It is! what's happened to ZOE?!
I fully agree, the mere fact that they don't mention K2 at all disploves any supposed authoirty or insight they claim to have.
@@tifqureshi3895 Absolutely. Their expensive 'personalized' diet which measures the tiniest fluctuations of glucose levels as if that is significant is a great money maker but not a reliable contribution to information on the gut biome. I don't know why I watched this except to wince. And it's dangerous if it influences people to stop taking Vit D (which is a hormone, not a 'type of steroid') we all could go on and on .... sigh.
A few thoughts on this interview...
Jonathan's interview with Dr Federica Amati and Dr Tim Spector is quite interesting, but in some cases it is not conclusive and some important aspects were not covered.
I also got the impression that the views were a bit entrenched, statements were made cautiously and sometimes seemed fearful.
What was positive was that both experts consider vitamin D to be important for humans. In addition, they tended to see additional calcium supplementation via food supplements as harmful unless prescribed by a doctor. Calcium is sufficiently absorbed through vegetables, fruit and dairy products.
Both experts therefore regard vitamin D (steroid hormone) as important, but are of the opinion that 400-800 iu daily is sufficient, and also refer to sun and food, although it is known in practice that sun exposure is perceived to be too low and food is naturally not sufficient. This does not fit together. No adult can get out of a deficiency with the dosage mentioned, unless one is satisfied with vitamin D levels of approx. 18-24 ng/ml. (Studies show, for example, that good bone metabolism only takes place above 30 ng/ml).
The topic ‘What is a good vitamin D level?’ was not addressed at all. Consciously?
The most important cofactor, magnesium, was also not discussed.
Question from Jonathan to Federica: ‘Can you be vitamin D deficient without experiencing any symptoms?’ Answer from Federica: ‘Unlikely.’
Frederica probably doesn't realise that vitamin D deficiency often leads to silent and insidious symptoms that people pay little attention to or don't even notice, even though they are present. Over time, these symptoms then develop into complaints and become clearly noticeable, painful, etc. Many doctors can misinterpret these symptoms.
Examples: muscular problems, hair loss, unexplained tiredness, exhaustion, low spirits, depressive moods, concentration problems, skin and nail problems, more frequent viral infections, poorer wound healing, to name but a few. The negative influence on our bone system anyway... The influence on cancer, diabetes, cardiovascular and autoimmune diseases too.
There are also studies of all three that show the connection between poor levels and diseases. Or the positive influence of good levels on a variety of diseases such as cancer and autoimmune diseases.
Federica talks about the cofactor vitamin K (but means K2) and the indication that vitamin K (K2) is formed in the intestine. However, the possibility of converting K1 (!) into K2 is reserved for only a few people, and only if they have the right bacterial strains and an excellent gut.
In my view, some of the statements were incorrect, inadequate or contradictory, especially the missing aspects about a good vitamin D level.
Greetings from Germany.
Very thoughtful. You have put into words what I thought of the podcast. Thank you.
@@moseaitch88 🙏
Well put.
There is no mention of calcifediol either in the video.
@@Celticspy911
Thank you...
Yes, but fortunately the interview did not also include calcifediol (calcidiol). Then Tim and Federica would probably have had to endure even more negative criticism.
@@Fitundgesund100 Very good points, and helpful.
I also had nagging doubts as to the possible bias in their interview.
I have listened to numerous professors talking about the benefits of vitamin D3 + K2
It seemed like they were using circular reasoning to keep coming back to diet and fruits and veggies.
As ZOE is a business, you would have to address the motives.

Is this the same VITAL trial that chose people where the majority already had Vitamin D levels at 30ng/mL, gave those 2000IU a day, but all participants (including the placebo group) were allowed to keep taking 800IU a day (if they were already), and then didn't find much difference between the two groups? Yes, it was a stellar trial, almost like it was designed to show no benefits. A few other points, whilst common in the US, dairy is rarely fortified with D in the UK. Mushrooms have to have Sun exposure to create any D, so check the label. The best food, oily fish, typically has about 500IU per portion, so just enough to prevent rickets. Other foods have significantly less. Vegetarians/Vegans will have great difficulty getting any meaningful amounts of D from their diets. Vitamin D takes weeks to be metabolised into a useful form where immune health is concerned (basically, you will not see an immediate benefit) and then much longer to be stored as a reservoir in fatty tissue where it can be drawn upon when we lose the higher Sun. It then has a half life of about 60 days. In the UK, the Sun is too low in the sky for about half the year to provide any significant D through UVB, so 3x60 day periods. I'm sure you can do the maths and work out what that means for your levels by Christmas and beyond. You can get 10,000 to 20,000 IU for about 20 minutes full Sun exposure during midday in the Summer, and yet there is fear-mongering here about taking a few thousand IUs in a supplement everyday? Too much paracetamol is toxic, too much Vitamin D is toxic, and guess what, too much water is toxic. If you really are worried about toxicity, get a blood test before supplementing, then re-test 3 months later. Different people do metabolise D at different rates, and there are many factors that influence this, so don't assume that if you friend is taking X amount of vitamin D, and their levels are 30ng/mL after 3 months, yours would be the same. There is so much really important information missing from this podcast about D, it's quite demoralising.
Totally agree. I don’t remember a Zoe podcast with so much criticism in the comments. They really need to start including citations to the studies they mention.
Completely agree and the VITAL study shows a 20% decrease in the risk of developing autoimmune disease which is so significant given the pandemic of autoimmune disease. So disappointed with this podecast.
@@markparker5585 I thought the podcast was one of the weakest.
I would highly appreciate the references to the studies snd clinical trials mentioned so I can go through them and make sn informed decision.
Is it possible ZOE?
Totally agree with you, There was a lot of scary nonsense about overdosing without any mention of eating fermented cabbage. I thought Zoe would be all over that 😠
I’ve started questioning everything, especially government health advice! After reading "Health and Beauty Mastery" by Julian Bannett, I completely changed my habits. This book reveals so many shocking truths about the health industry!
Exactly!
Yes, unfortunately it's all about profit, nothing more, nothing less
@meditim2032, can I check how you came to find the book by Dr. Julia bannett? I guess what I am asking is how truthful the book is, too????? Seems everything these days is for money.
How was the book. Worth the read or not.
I am more inclined to believe the interview with John Campbell and Dr David Grimes. Dosage depends on weight, colour of skin. The older you are as skin dries and does not absorb as well from sunlight. I had blood test and was insufficient. Took supplements according to my weight and after another test I had sufficient. You would have to take huge amounts to be harmful. No money gain from Dr Grimes but a life time of study, knowledge and research.
Yes that was a brilliant interview!
That was one instance where John Campbell was absolutely correct
This comment needs a gold star ⭐⭐⭐
Yes, and disappointingly Tim Spector seems to be referencing bone health and metabolism as the be all and end all of vitamin D needs, when others argue that's the tip of of the iceberg in terms of needs .. I'd like to hear a far more nuanced debate that accepts this, evolutionary levels and immune system requirements rather than simply backing up NICE recommendations .. the inference that Campbell and Grimes are both influencers and influenced by the supplements industry is also very disappointing.
@@bruceanderson1044 Campbell is a massive grifter now. But his vit D videos were made before he 'turned', and he was right about vitamin D. He pretty much backed up everything my respiratory consultant said (good vit D levels are essential in asthmatics)
What about the severity of COVID infection in elderly people being worse in those with low level Vit D?
Reverse causation is also well documented, meaning that illness lowers vitamin D levels rather than low vitamin D causing the illness. In the same way blood levels of cholesterol are lower when people get sick so high levels are not necessarily a sign of good health.
@@rickduker4969 Low vitamin D is a result of modern lifestyle. We know that most people are low vitamin D without having to look at reverse causation. You can bet your boots that most of those people would have had low vitamin D irrelevant of illness.
@@rickduker4969 it then makes the case for taking vit D when you are ill or injured. As the body will use the vit D it has, causing levels to drop.
@@rickduker4969 you mean, high levels are not necessarily a sign of poor health.
@@ajclark538 it takes weeks to months to change D levels, and there's not a recognisable level that suits everyone.
In the interests of balance, for anyone new to this topic, I was diagnosed by a leading endocrinologist at Addenbrooke’s Hospital with Vitamin D deficiency - the 25OH test measured me at 8 nmol/l compared to the expected normal of > 50 nmol/l - even though I walk and cycle thousands of miles every year, eat a healthy diet, and are trim and fit (BMI of 20.0). I’m mixed race and live in the UK. I presented with many symptoms including muscle fatigue and body aches.
I was put on a high dose of Vit D3 initially (40,000 IUs per week), stayed on this for a few months and have since supplemented with around 5,000-10,000 IUs per week. Most of us don’t have the luxury of being able to measure our VitD levels, so maintaining a preventative level of supplementation seems sensible. My symptoms have not returned.
Key message from this podcast is that everyone is different, so educate yourself, try and get yourself professionally tested and if you have any of the key symptoms then take a modest supplement, otherwise do nothing.
I had almost the same experience, doc put me on 40,000 iu per week to start me off, I was fine within 2 weeks. I also happen to live in a hot country, it shouldn't have happened, but it did. My pharmacist was telling me that since Covid, there's been a huge increase in people being prescribed vitamin D3.
Much better explanation of dosing levels from an actual Dr here th-cam.com/video/2hO7fniCbmw/w-d-xo.htmlsi=k4egRKYCYCJb6hMn
My daughter who was in her teens had huge vitamin D deficiency. Was put on a high dose for a couple of months to get her levels up. She was exhausted all the time, ate well and loved sunshine. I wish testing was an automatic health check. She now takes 5,000 ius which is right for her weight.
i have very similar experience. I am from south of Europe, moved to Finland (~15 y ago) and at that time nobody told me I should get vitamin D supplements, and the only dose available was 5ug!! After a few years I have developed different symptoms, and no doctor could help me until I figured out it was vit D deficiency- at that time "normal" base here was 10x lower than nowadays, but I read work of dr. Stasha Gominak and followed her advice, supplementing with enough does of vitamin D (had to order from abroad), and B-complex. Within 6 months (winter time) my symptoms were gone and nowadays I regularly supplement and also my children to stay healthy and strong! It is too bad that we must be own doctors because idiot doctors don't understand that over here where I live we don't get correct wavelength of Sun from August until Jun! In addition, summer over here doesn't do much for me due to my darker skin, so I must travel south. I have never burned my skin in my life, but I do gradually expose my skin to build up the tan.
I interviewed Prof Michael Holick when I was university studying clinical nutrition 15 years ago. Even back then, he was saying that the 50 nmol/l was too low and that it should be 100 nmol/l.
Over an hour of discussion and no mention of K2... seriously? Zoe please lift your game.
I agree, the co-factors (A, K2, Boron, Magnesium) are super important for optimum Vitamin D levels.
I was also waiting all the way through for them to mention vitamin K2 - especially when the topic of calcium came up - and particularly as K2 is found in fermented foods which are good for the microbiome

I’m a nurse. Our own doctors recommend we take vit d supplements cos we do long shifts indoors and don’t get sun
Exactly! I would have thought it was important for people who work permanent nightshifts too.
Yes, if you are in a group that doesn't get enough sunlight (us night shift people included) or were specifically recommended to take vitamin D due to deficiency, then yes, you probably should supplement.
The NHS only recommends 10mcgs (or 400 IUs) a day, tho.
@@jane5789 general recommendations and what your doc tells you to take based on your body and circumstances are very different 😉
@@newdawnfades263 I also think that patients that are in hospital for more than a few days may need supplements, for the same reasons. Modern hospitals often have very little sunlight, little to no windows and little access to green outside space. ITU and ICU patients particularly can be at risk of low Vit D levels and have no access to infrared light.👋🏻 from a nurse in Germany
Michael Mosley did a podcast on why vitamin D was one of the only supplements he recommended. How is anyone supposed to make an informed decision on this?
If I do the opposite of what Tim Spector says I'm usually on the right track,imho of course 😮
@@gruber1650 Spector says a lot of good stuff about diet but also has a habit of basically trying to say everything is wrong apart from his on gut health theories. Yet the evidence basis for this is always quite tricky to pin down. He’s competing for a limited slice of the self-help/supplementation market. Profit is his main objective.
Science is a process. It is the best method of trying to understand the world. As we gather more evidence, the conclusions become firmer. You can choose not to believe in the scientific method, but any other form of understanding the world is infinitely worse. Tim himself stated that he is open to changing his mind on vitamin D if the evidence supports it. He is a mark of a good scientist. I myself have been taking 4000 IU of vit. D a day and after watching this video, I'm going to markedly reduce it. You might decide a different course or action. This here is the gray area, which science embraces. This is the nature of the universe, us incrementally understanding it, sometimes one foot forward, two feet back, sometimes two feet forward, one foot back. Stay healthy.
I find that Tim Spector likes to find something which lots of other scientists/Doctors like and then trash it! I do watch these things and also have some of their books and found that each book has points in it that are different from the earlier ones and a genuine statement of “I got it wrong” however, your right how are we supposed to judge what’s right or wrong. Basically a little of everything and not too much of anything will probably do us all fine 🤔😃👍
These questions are very complex and there is ongoing research so probably no final definite answers to them yet. How else are we making any judgments if not based on actual scientific research?! Just opinions and/or manipulations for

I listened to this entire video and decided that I will continue taking my D3 and K2 supplements as Dr John Campbell suggested. Sadly I have lost trust in the Zoe health advice. I think Tim Spector is also wrong about unprocessed red meat and animal fats.

yes, Tim Spector seems not to know that it D is crucial in the metabolism of neurotransmitters., So, It does not matter if vit D causes mental health problems or not. What matters is that low vit D makes it more difficult for doctors like me to treat mental health problems.

I'm in my late 60s and live on the west side of the UK. I walk my dog daily but I no longer wear bikinis or crop tops and seldom wear shorts or short sleeved T- shirts, certainly not in the winter. Even on the beach, in winter, the dog walkers are wearing wellies and wind proofs. We don't all live in care homes, but still wrap up. That with our declining ability to synthesise VitD means I supplement.
You don't need to supplement vitamin D. Very few people are deficient in a meaningful sense.
The same could be said about people wasting money on Tim Spector's "Daily 30" mixed seed supplement which works out at a staggering £120 per kg, when people can easily purchase a selection of mixed seeds themselves for a fraction of the cost! We all know that eating more plants is good for us and therefore we don't need to waste loads of money on Tim's seed supplements and books to do this!! He is simply raking in 💷💷💷 from very clever marketing.
You can actually buy a year's worth of vitamin D for about £5, which isn't really breaking the bank for most people.

What a misleading video this is .... yeah lets all expose ourselve to the Sun and get skin cancer.
Most of us need Vitamin D supplementation, especially in the Winter.
What is happening to Zoe?
It is steadily going down the pan since Steven Bartlett came on board .
To be fair I've literally never heard him promote it and have no idea he even sells anything like that.
between October and early March in the UK we do not make enough vitamin D from sunlight.
You need to get out more!
@@ratmanbug when there is a break in the clouds it’s too cold to expose enough skin. I also work so can’t get out when the sun is out.
@@ratmanbugIt doesn't matter how long you're outside for if the sun is low in the sky, like it is in the UK between October and March. It is literally impossible to synthesise any meaningful amount of vitamin D in the skin when the sun is 45 degrees or lower in the sky because the thickness of Earth's atmosphere at that angle filters out UVB radiation. Rule of thumb, if your shadow is longer than you are tall you're not making vitamin D. This October to March window is even longer for people with darker skin tones.
The sun needs to be at a 45° or higher angle in the sky to be strong enough to make vitamin D - otherwise too much of the necessary UV component is blocked by the atmosphere.
Sun elevation needs to be above 50deg to get Vit D - hence only April to Sept in UK
I was severely deplete of vitamin D and had lots of bad symptoms. Taking vitamin d has definitely helped me, first thing I’ve ever taken that I actually felt a difference. I’ll stick with it and can’t be bothered watching all of this video, too much conflicting info.
If you'd stuck with it, you'd have heard them say that some people do indeed need supplements, like you, but the vast majority of us will be better off taking a walk in the afternoon and eating a few specific foods.
I've not caught as much as a cold for several years since I supplemented vit D and I used to be an ENT disaster zone
If you had bothered to watch the video you would have heard them say many times that the small fraction of the population who present with your symptoms benefit from taking vit D supplements.
@@clairejauffret And? Data sets of one are not useful.

Rather disillusioned by this podcast that might well put me off Zoe in the long run. So much more info about the beneficial effects of Vit D on the immune system out there with research to back it up especially with reference to flu, chest infections (apologies no link) and really, are we still banging on only about its effects on bones? That's so well known and documented and has been for many decades. Move on. Stick to the microbiome studies, Tim.
Please provide links to research and reference material to back up your assertion.

@@markparker5585never did. They loved pushing covid fear at Imperial...oh Bill Gates bankrolls them.Go figure.
Quite agree. The main area that Tim Specture seems to be behind the huge amount of research. Living here in Cumbria we are getting almost zero natural VitD.
Me too. Cranks Corner. Not for me.
so it prevents MS and helps in inflammatory diseases like Chron's and cancer but only people in these sub groups should take it? Surely there is a continuum of benefit and therefore makes sense to supplement it if only as a potential preventative measure - agree that it is very complex but not convinced at all by the arguments here.
They ‘forgot’ to mention the VITAL randomised control trial showed 2000IUs of vitamin D per day reduce the risk of developing autoimmune disease by 20%. So if everyone took 2000IUs a day of vitamin D the NHS would save so much money given the explosion in autoimmune disease. This whole podcast was absolutely rubbish as most comments indicate.
If a person has the money to waste on tablets, I guess? But good food and activity is far more beneficial. But that approach doesn't make money for supplement companies.
@@mariarotaru2069 despite overly enthusiastic headlines, actual risk reduction was just 2.5 cases out of 1,000. Hundreds of people would need to take vitamin D daily for years to prevent a single case of autoimmune disease. Vitamin D can interact with other medicines, and taking high amounts of vitamin D can be harmful.
@@sprightly75vitamin D tablets (including K2) are incredibly cheap - you can get a year's supply for about a tenner
Intoxication with D is pretty difficult
Indeed. There is very little evidence of it happening.
Ooh i find it very intoxicating....
With no first hand experience, but having read a fair amount of literature, there seems a clear overlap between the defined symptoms of vit D3 toxicity with magnesium deficiency (hypomagnesia) as well as K2 deficiency in relation vit D3 ratio (hyper-calcification)
Agreed you need to take very very high amounts (we are talking tens of thousands of units on a frequent basis for an adult) to get intoxicated, it is possible and it is very dangerous but it is extremely rare. The boxes containing such doses have warnings and guidance about not taking them daily but every week or once a month for example.
Is that why it's used in rat poison?
A few years ago, I went for a blood test
The doctor said that my vitamin D was low, so she helped me supplement vitamin D. After taking it, I started to have many problems. First of all, I started to become depressed, anxious, have high cholesterol, high blood lipids, and xanthoma on my eyelids. I had no idea where it was. This is a problem because I am a person who eats very healthily and exercises. I just found out today that vitamin D is responsible. It’s terrible. Now that I stopped taking vitamin D, the xanthomas on my eyelids stopped growing. But in order to find out the truth, I took it again, and xanthoma began to grow on my eyelids, and I started to become irritable. Also constipated.
I respectfully disagree with their position. There are hundreds of research papers that demonstrate the benefits of Vitamin D supplementation. For these supplements to be effective and yield evidence-based results, the dosage must be appropriately tailored to each individual. This is likely the reason they believe it isn't effective.
They didn't say no supplements, they said supplement if you're not getting 400 to 800 IUs daily. BTW, the US endocrinology association no longer recommends vit D supplements either.

Perhaps vitamin D is a thorn in the side of medical "science" with its "studies" mostly paid for by industry because it actually helps to prevent diseases and mitigate disease progression.
Speecter isn't 'medical scince' he's a nutritionist with a fixed set of ideas and a hatred of supplements - 'you just need a healthy diet', but D is the most difficult chemical to get suffiently when unable to make it in skin - whether because living in the north or from age or skin colour.

Same for running water. Better patent it and make it expensive.
Grabbing hands, grab all they can.
Gotta do something to promote your business, even if your products are low margin. But promoting vitamin d can also help out those who sell blood tests and supplemented foods
Hmm, that’s not a viable business proposition. Cheap goods with no patent don’t sell well.
I find this show can get guests who haven't spent a lifetime in certain studies going against a lot of research from people who have spent decades specifically in that certain subject.
There didn't seem to be much chat about darker skinned people living further north. Also what happens when we have a poor summer, with little sunshine, relative to a better year?
Also didn't discuss you have to have major parts of your body's skin exposed. Something some cultures discourage. Just having your head/face/hands outside isn't going to cut it!
I guess they gone woke now as skin colour is not allowed to have any effect on vitamine D levels and your health
Tim Spector should call Dr. Anthony Fauci and educate him on why Vitamin D doesn't help with a certain respiratory disease. I think Federica was much more measured and scientific in her presentation. Spector has a completely closed mind on this. That's too bad.

They ralked about dangers for heart health with excess combined D and Calcium.
My understanding is that it is nearly impossible to make vitamin D in winter months, particularly if you live above 37th parallel, ie above Sicily. This is because the earths atmosphere filters out theUVB which is needed to make vitamin D. Not saying we should take supplements, oily fish , mushrooms etc are great but just clarifying that sunscreen won’t make a difference. I live in Switzerland where sun screen is essential in winter due to UVA. We still won’t make vitamin D in winter without sun screen because there is very little UVB.
I take 5000 ius of vitamin D3 gel capsule per day for the last 5 years. No colds or flu since, however, if I feel I'm getting a cold i increase to 10,000 ius for a few days. Also take K2 as well but some people maybe allergic to that...
Same. Much fewer colds although I have an autoimmune disease.
I take around 6000 iu a day in the Winter through to around May time, (in Berwick NE). I have noticed a huge difference in my resistance to infection and I've never shied away from the Sun.
look up high dose vitamin c as well. It is a very important vitamin / hormone
Exactly the same, used to get colds etc all the time - been taking vitamin D3, K2, Magnesium etc - and touchwood no colds since pre-covid. Guess though everyone will have a different story on that on.
Watch Dr John Campbell's videos on Vit D and K2, endorsed widely by reputable research and by world-renowned oncologist Professor Dalgleish. Much more convincing than this.

How did it cure your IBS, if you dont mind me asking? What have you changed and what were you doing prior?
I cured my IBS by cutting out most plants from my diet. I suspect you might have added more plants. Both of us probably cut out the ultra-processed foods. Maybe that's a great first step.
@@trail.blazer actually, Ive had IBS since I can remember. My diet used to be mostly meat, dairy and eggs when it all started, and for many years after that.

Ive tried fodmaps, probiotics, high protein/fat, high carb, lower fiber, higher fiber. Doesnt seem to change a damn thing.
@@Progressivelyyou I tried all those things. Also a low histamine diet, not that I expected much from that. For me, fiber made it worse. Fiber supplements made it way worse. As I got older, the fiber was more of a problem.

Let's just add in all the other vitamins, minerals, and other nutrients while we are at it for proper balance 😅 there's a reason no one can make these types of nutrition videos without taking flak from random people on the internet. You really can't cover everything in one subject, one video.
I agree, we can't all get a suntan like Tim. It doesn't make sense, Dr Amati says can't get enough through food but you shouldn't take a supplement? I can't go in the sun so have to take supplement, I was taking g 8000iu and my blood levels were only 75nmol/l where 50-100 is normal so don't think the amount of supplements recommended is enough, I take mine with lots of Kimchi for vit K2, it stinks.
I had mild psoriasis for years and also had low Vitamin D. When I started taking Vit D supplements it went in a few days. I went on holiday for a week and forgot the jar, and the psoriasis came back. When I came home I resumed the Vit D and it went again.
The problem with the research is that it is over simplified and there are more variables involved to see results. First, vitamin d supplement is only one chemical. In the body, vitamin d analogs are sunlight (UVB spectrum) between 11am to 1pm "activates" the starting process on the skin. Also, secondary vitamins super important, K2 A and Magnesium. The vitamin d improves calcium uptake, so getting k2 is super important to manage calcium. If not sufficient secondary vitamins then calcium becomes a problem.
To increase bone strength, start with the signal. Jumping rope twice a week, rebounder, vibration plates, and simply jumping up and send the signal from brain to bones. Next, increase magnesium to much higher doses. Phosphorous in foods will increase parathyroid hormones and thus reduce mineral in bone. So phosphorous shouldn't go over 350 per day. Also include boron in diet. Last ingredient is lots of time. Those following this protocol will not have weak problems.
What really would be interesting? A discussion between dr. Spector and drs. David Anderson and David Grimes!
wouldn't it.....!? I think he wouldn't only be out of his lane but he'd get run over.... Dr Grimes was an actual practising clinician seeing real patients.
I quite agree. Dr Grimes also said older people or anyone with dry skin can’t convert Vit D from sunlight because they don’t produce the skin oil that’s required for the conversion. Dr Grimes recommended 1,000 IU’s per 10Kg body weight daily. He takes the equivalent of 8,000 IU’s daily in a single dose each week.
Was thinking the exact same thing. I would love to hear Dr Grimes's opinion on this disappointing and in my opinion inaccurate podcast.
And don't forget to include Dr Berg in the discussion 🙂
Tim keeps talking about fractures, most do not disagree on this. We should be focussing on the effects of supplementaion and the effetcs on the immune system. Particularly, studies when people are taking sufficient dosages and getting their blood levels up above a certain level.
Agree. Dr Berg knows a whole lot more on this d3 subject. Except he always insists on taking d3PLUS K2. Spector makes no mention of K2 or magnesium. They all work together.
They do seem to be stuck in the past, as if Vit. D is mostly about bone density.
Spectre needs to give it a rest! There have been enough studies done that show the effectiveness of vitamin D. I find Spectre boring, to say the least.
A general audience could really do with a an informed, practical, clear summary of why vitamin D is important and what, on the basis of cited studies, they should consider doing about it. This, alas, is not it.
Also saying only take calcium if your doctor prescribes it - surely it would be better to advise some strong questioning of any GP routinely prescribing it for elderly patients as many GPs seem so ignorant of the risks of what they prescribe.
My GP no longer advises taking calcium supplements due to the recent papers pointing out the negatives.
The last person I would ask about nutrition is a GP. How many hours of training in diet and nutrition did they receive?

Important point that Dr Amati mentioned regarding people of colour (particularly darker skin tones) not always being able to get enough vitamin D from the sun in the Northern hemisphere (even if they spend time in the sun). Some people in the UK also have their skin covered up (apart from face) by clothing even in the summer due to religious and cultural reasons, so are unable to get enough vitamin D from the sun.
Well, I had extreme fatigue and virtually no Vitamin D in my system, a doc prescribed a high dose and after just a few pills I was fine. Since then, I take it periodically when the fatigue creeps back.
Interested to know if your Dr prescribed Vitamin K to take alongside the D, or mentioned you should take them together?
Nowadays we spend 95% of time indoors in general. If we go outside how much of our body is exposed. Not much, if it is we pour sunscreen all over it
To be fair Spector did recently say that wearing sunscreen was wrong - and he got piled on by the whole science community 😂
Great thought from Tim. Its good to listen to all kind of comments and look who puts the money on the statement. Everybody can be wrong. Im 70 and have seen lot of comments that has changed during the years no matter what professor so its very good to doupt things and make up mind on real studies and to think that people have lived long on this earth. With different lenght of life of course. look at your own body and see its reactioons. Ive never used any kind of creams, i love to be in the forest and ive never burned my skin.. i get brown yes but no burns. Summertime i cover with a cap and think when i need clothes to cover. Never taken supliments or medicine but good food and lot outdoors. We are different in our bodies.
Tim is becoming a broken record - everything is about food variety. I agree that lots of plants and plenty of variety is probably very good advice but when a scientist tells you that spending 5-10 pence per day on a supplement is a waste of money and can be better spent on increasing your diet variety then you know there is some kind of bias in the reporting. At 35 or 70 pence per week you're looking at adding an extra small sprig of broccoli or half an avocado. Tim said our bodies stop accumulating Vitamin D when we have enough from natural source but we can take too many supplements - I'm struggling to understand how the body knows what source the extra Vit D came from - the body can distinguish vitamin D from sunlight and that arriving from a tablet . . .
Very well put! Great logic!
I agree mostly. I’ve heard that the body compensates for too much vitamin d being in the body when you go out into the sun enough.
Vit D from the sun includes UV, which is an important component. Your body stops metabolising vitamin D when it has sufficient amounts.
He said our bodies naturally stop *synthesising* vit D when we have enough from sunlight/food. Synthesising/produce
You don't absorb Vit D directly from the sun. You manufacture it, and your body knows when to shut down the assembly line (assuming you still live in your ancestral environment or one similar to it). But if you take preformed D, then your body can get overwhelmed if you take too much.
It's well known that the NHS recommendations on Vit-D are woefully low. The upper safe limit for daily vitamin D intake for most adults is 4,000 IU
the NHS lets people down on multiple fronts. Nothing new here
I take 10,000 IU per day as a maintenance dose along with Magnesium, Vitamin K2 and Zinc. Did you know if you sit out in the sun during the summer for 20 minutes your body generates 10,000 IU from the sun's rays. Some people spend hours in the sun, think how many IU's that will make. The NHS recommend people take no more than 400 IU a day. WHAT A JOKE.
THE NHS recommends 400 IU a day of Vitamin D which is a joke. If you go out in the sun for 20 minutes in the summer your body generates around 20,000 IU.
Since we're apparently all different on how well Vitamin D is absorbed, it's important to know what your level is. I have been taking 5000iu w/K2 for roughly 3 years and my Vitamin D level is only 46 ng/ml. I probably need to increase my D3 to 10,000iu.
@dreamcaster99 Yes, but your body is in complete control of the vitamin D it makes so it may only use 1000 iu of that 20,000. However, exogenous vitamin D your body doesn't control so it can do harm
I had low mood, anxiety, bodily aches & pains, poor sleep and some psoriasis. The GP suggested it may be a vitamin D deficiency. I initially thought this was strange as I eat a healthy varied diet and take a multivitamin and mineral supplement containing (a ridiculously low level of) vitamin D3. I live in the UK though and only get a few months, at most, of decent sunshine each year.......& I work indoors. Anyway, I added a daily vitamin D3 supplement to my diet and the improvement to my above mentioned symptoms over time was nothing short of spectacular !! This was a very disappointing, and narrow in scope, review of vitamin D by ZOE and I heard little information with much credibility from Tim Spector, frankly. I shall most definitely be continuing to take my daily maintenance dose of 5000iu of D3 throughout the summer and 10,000IU of D3 throughout the winter. In addition to taking K2, Zinc, Magnesium & Omega-3 fish oil ..........which I suspect Tim Spector also feels I don't need and am wasting my money on ..!
Yes but before the modern era, people spent many hours outdoors all year around. Now we are much more sedentary, few people work outdoors all day long. As humans, we are designed to be outdoors a large part of every day. So it's highly unlikely that we have 'enough' vit D - maybe enough to survive and function, but logically, we cannot have ideal levels for our species.
There is also the simple fact that the skin has to be exposed to create vit D. It's not going to penetrate jumpers, coats and jeans. So going out in winter in northern Europe is good for a bunch of reasons but it ain't going to give you much vit D when you're exposing at best the face and hands. Totally agree with Tim about sunblock though.
Very surprised and disappointed same as other listeners that Vitamin K2 is not even mentioned! What planet does Zoe operate on????
We also need near infrared NIR sunlight because of the benefits to our cellular mitochondria. One reason people get sick in the winter in northern climates is the lack of exposure to NIR. It’s hard to get sunlight on your skin while wearing a parka.
I don't think one should listen to anyone thinking it is the highest and final truth. There are studies on vitamin D3 safety, like "Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial", which did not find any major negative adverse effects from even vitamin D doses up to 10 000 IU/day. While such high doses seems to be safe, most studies on efficacy are done with dosage of few hundred IUs daily, hence they did not succeed to prove efficacy... As always, the "experts" are just messing up with peoples minds using their "higher understanding" and imaginative knowledge.
Most people in the UK don't spend lots of time outdoors ... and even less on days when the sun is shining & they are "sporting lots of bare skin"
... most people will have covered skin, even on the few hot sunny days that the UK experiences
I think this is an unsubtle episode.
I would suggest you don't get sunburnt ever if you can help it.
I would also suggest it's not possible to get sun exposure regularly in the UK especially if you have an indoor job (perhaps why we then go and get sunburnt it is sunny).
I would recommend anyone with health issues takes vit d at the very least in the winter months especially if you start getting joint and muscle pain. Bear in mind that taking high doses of vit d could also lead joint and muscle problems.
If you are well, have a good diet and are often outside then yes maybe you don't need a supplement.
Skin cancer is still a thing. Last I heard there are more cases in the UK than Australia because we don't take it seriously.
18:40 "the industry has made a disease where none really exists" Is a little bit cynical of Professor Spector tbh. There's sod all money in the production of it as there's no patents or other IP issues so any johnny come lately can get in on the game.
On a side note what are there opinions on combining vitamin D with Vitamin K?
Vit K2 is a mitigation to hyper calcification.
@@ialz-digi So they say, but do we have evidence for that?
Many industries create disease where it is not … check out menopause and HRT…
@@spurgendahl There appear to be quite a few studies supporting that.
Your wrong about the economic return. It is cheap to manufacture and huge revenues can be generated by mass sales.
Lots of stuff I don't really agree with here, but I love that she said for some people going out in the sun WITHOUT SUNSCREEN is a GOOD thing.
Barbara O'Neill said you don't need sunscreen, you need a watch😁
I've definitely felt benefits, particularly regarding depression ( 1000iu-5000iu) seems to make a dramatic difference, especially in Northern climates where we get less sun.
I had four different cases of chronic inflammation and low levels of vit D (29). I got on a dose of Detremin that doubled and tripled it, 3 months later all the inflammation ended simultaneously without ANY other changes.
Zoe has been losing me slowly in the last few months - this episode has resulted in closing my Zoe membership and subscription.
My personal experience is that a small dose of Vitamin D3 when needed lifts my mood. Thinking of this in relationship to
S A D (seasonal affective disorder).
I will add my anecdotal experience which I realise many from here will disagree with. I used to be vegetarian and ate lots of seed oils. I would burn in an hour of cycling in New Zealand sun even on a cloudy day, so I always used sunscreen. I have not consumed seed oils for around 5 years and now mostly animal based diet for over 3 years. Since changing to that, I can now go out in full sun (no clouds) for 3 hours with no sunscreen and zero issues.
I do sailing and if I'm out on a boat for more than 2 hours then I do use sunscreen. I'm not claiming that I am invincible to burn but it does take much longer.
Was it the diet change and removing seed oils? Who knows but it is somewhat unlikely to be much else.
Without supplementation and during a summer my last 25 Hydroxy D test was 151nmol/L. I do now supplement 4,000 IU daily during winter.
Yes, you can overdo vitamin D supplementation, but you do actually have to do silly things. It is very unlikely anyone taking 5,000 IU a day is going to even get close to issues.
There's no consensus on the correct levels of vitamin D.
@@bushtucker66 Correct. So, what would you like your level to be? Less than 50 or more than 100?
Hi Tail Blazer - Yes I've had the same skin sensitivity change since removing seed oils. I'm blond and I used feel the 'burn' on my skin in 5 mins in UK summer sun, now I will sit for 3 to 4 hours in Spanish sun, then I might add some sun screen, but i find it almost impossible to burn now. I only use vegetable oil to lubricate my chain saw now!!
I am really surprised not to hear any mention of the fact that vitamin D3 needs vitamin K2 and magnesium in order to be able to process vitamin D supplements. I once spoke to a herbal nutritionist who made me promise to take a handful of greens (for the vitamin K2 element), in combination with the liquid vitamin D3 supplement. I know that I my health is very much better having worked outside in the sun than I do in the winter.
My daughter was found to be severely Vit D deficient. She was put on 50,000 in a week for a couple of months.
Typically doctors supplement 50,000 IU weekly using D2 and not D3. The effect of D2 is different to D3 and does require much higher doses.
When one ages the skin begins to decllne with the necessary cholesteral to synthesize Vitamin D. Also in the winter months taking Vitamin D supplement is imperative. It is really important for older people to take it. I had Osteoporosis and could not tolerate the drug for it. I began strenuous walking, taking 2000 units of Vitamin D, K2M7 and Magnesium. My osteoporosis went away.
I can buy a years supply of Vit D3+K2 for about £6.00 - I don't think many commercial producers will get too rich at that rate... I also notice that the NHS, as stated in my medical record, say that many people benefit from having 50 to 75 nmols/ litre, and that the elderly suffer fewer falls when their levels are 100 nmols/litre ! There is no way I, living in the UK, can get any VIT D from the sun between Oct and March, without either taking supplements, or going to a Tanning Studio (with increased risk if skin cancer)
Your stated values of 50-75 nmol/l are too low, because bone metabolism, for example, only functions properly at levels well above 75 nmol/l, and levels of at least 125 nmol are helpful for the immune system. In autoimmune patients, positive effects of vitamin D are observed when the level is around 175-200 nmol/l.
@@Fitundgesund100 I was quoting the UK NHS. My own level is currently 150 nmol/L - and I plan to keep it there!
In Saskatchewan, getting outside in -30 to -40C is not happening for me!! If I go out, I'm wrapped up head to toe with no skin showing. No possible way of getting sun exposure!
Dr Cambell has a positive opinion and it can be very effective
Also I did Zoe for 6 months but developed an allergy to being patronised and spoken to as though I were a small dim child and recording all you eat on the terrible app is a full time job unless you fast which is maybe how so many people lose weight on it, they'd rather starve than go through the meal entry process
Just tuned in and haven't finished watching this episode yet, but I have to comment about my own experience. I spend hours in the sun every day, I do not use sunscreen, and yet I am still severely deficient in vitamin D. Blood tests showed my levels of vitamin D were in the single digits. Perhaps I'm just part of that small minority that actually needs supplementation.
As you age, the body is not able to synthesise it as well from sunlight
People with autoimune issues absorb vitamin D with problems. Like Hashimoto. I was told what others get in 20 minutes for a Hashimoto sufferer can take up to 8 hrs.
This is cobblers. There are many papers pointing to the benefits of vitamin D
@@jimhignett6993but not vitamin D supplements.
Combination with Magnesium helped me absorb the vitamin D either from sunlight during summer time and with supplement (the liquid one with olive oil) the other months. These I could have proved having blood test to check the improvements (I'm now doing it twice a year to check the figures!)
I'm sorry I think ZOE has gone to the DarkSeid. Anyone know their financing?
In the nordic countries vitamin D is a must during winter. There is no sun and when there is, we are covered in winter clothes. During winter it's dark when I go to work and dark when I get home (7-15 work day) so there isn't even possibility to go out to enjoy sun for many reasons.
The UK is the same during autumn and winter, I won't see much sun from now until March. I'll think I'll stick with my 4000 IU's a day.
Actually the Rcketts and osteomalacia were seen prior to WW11. The ministry of health saw to it that children got orange juice and cod liver oil and malt. These conditions reemerged in the ethnic populations with dark skin. One of my school friends had Rickets, but that was because she was born in a Japanese prisoner of war camp in Shanghai.
Vitimin D is important for thyroid mechanisms. If all cells in the body have a Vitamin D receptor then they need access to it. If there is only a limited supply available then some areas may not have the access they need. People don’t go out in the sun and if they do they often wear sun screen. Older people very rarely go out in the sun and their bodies do not process food as efficiently. Their immune systems are not as efficient either. For the cost of Vitamin D I will be continuing to take it, get the sun when I can and eat a good diet. I also take magnesium, K2, CoQ10, Complete EFA (Omega 3, 6, & 9) and extra vitamin C & Zinc during winter.
Correct! Well done,
I'm UTTERLY confused!
I have worked with a Vitamin D specialist and my whole family is on high doses of D daily for many years. I feel now that I am harming myself and my family.
I was told D/K/B’s Omega 3 and magnesium should be taken daily and the combination of those key. My husband reduced his homocysteine levels down to healthy readings by supplementing the recommended doses of the above. I respect Dr. Spector a lot but this talk is missing lots of context in my opinion
The statements in this interview do not stand up to scrutiny. They should be critically evaluated by everyone.
Didn’t learn much here…. It’s pretty clear that high vit D ( 60-80 ng/ml) is not a health risk especially if vit K2 levels (microbiome or supp ) are normal..
I've been lately thinking Zoe has been bought out the info lately is wrong. Unfortunately Tim's face is on every days news feed in Australia sent to my phone, that doesn't happen by chance "disinformation" tool.
Good luck living in west of Scotland and being able to get out for 20 mins sunshine every day! Also no mention of the menopause and risks of osteoporosis.
And the dubious benefits and considerable cost of Zoe… Spector is hardly an impartial voice in the “wellness” market given the questionable benefits and considerable cost of poo gazing and glucose monitoring.
They missed the single most important fact about vitamin D - Always take d3 (not d2) with vitamin k2 and magnesium.
One more thing - we are what we absorb. So, if you have leaky gut (most do), you won’t absorb the d3 so you need to take more.
The main ingredient in synthetic Vitamin D pills is Cholecalciferol which is also the main ingredient in d-CON rat poison.
@@Jeffs60exactly
Absolutely
You need Biron to absorb D3
Possible without K2 supplements if one eats fermented foods, e.g. tempeh, miso, sauerkraut, kimchi
I wonder if Tim has ever tried to get his doctor to do a vitamin D blood test? My experience is that it is impossible. Therefore, how are you supposed to know whether you have a low level?
Indeed, how do you know. I badgered my GP, the senior partner, he said he was not allowed to order the test, so he transferred me to a new junior GP. She ordered the test as part of a wellman test, with the comment that the lab might not do it. Strange comment, something else going on I thought. Surprisingly the lab did do it, 170nmol/L, she advised me to stop taking it as I was out of range. I had to tell her the NHS advice was 30 years out of date and was incorrect. She made no comment.
Yes, Tim can afford to get his bloods done privately. The rest of us have to guess.
Very strange that all of a sudden they say vit 3 builds up in your body whereas forever they say that's the opposite. In hospitals it's been proved with large doses of vit D and vit c does help recovery, it's the first time I've watched this channel I can stand the interviewers drawl, by the way how rich are Zoe owners ?
"There's no data for that" what a load of BS. What Tim means is " there's not a lot a money going in to research on alternatives to the massive global pharmaceutical corporations and instead a lot of money is absolutely going in to dismissing alternatives to pharmaceuticals...."
Thanks for the show. I'm a ZOE stan :) however, tend to be disappointed how "the scientists" only make mention of us dark-skinned people as an afterthought if at all. In Tim's case, he almost talks like we don't exist in these parts of the world too. It would be nice to see other scientists on your team who are capable of noting those nuances, especially on relevant topics like vitamin D.
Dr John Campbell has discussed with leading scientists the benefits of supplementation of Vitamin D3 (alongside K2 that was not mentioned here). I will continue to take the advice of Dr Campbell on this subject, over and above anything stated here. I'm very disappointed that fact based evidence linked to poorer outcomes for those people with low levels of Vitamin D was not mentioned, such as in the elderly, some ethnic minorities and the obese.
Agree with you re Dr John Campbell. His research and knowledge is superior to Prof Tim Spector's on vitamin D.
Also, what about the alleged ability to synthesize reduces with those less young?
Such a good in-depth insight using a common sense approach with some good humour in it as well. Thank you for that.... great research. Tx
A very disappointing and longwinded podcast! 1. Not much about older people and how older skin can or cannot absorb Vitamin D. 2. Nothing on how other vitamins and minerals affect the uptake of Vitamin D. 3. No information on the many benefits on the immune system. 4. My story: I am 83 and have always led an active outdoors life and had a good varied diet. After age 50 I began to suffer from difficult outbreaks of oral herpes with symptoms, not only of painful coldsores, but also raised temperature, facial neuralgia and aching body that affected badly me for roughly two weeks out of every month. I sought help and after some years I was prescribed preventative antiviral medication to take every day. This helped until I developed serious side effects and had to stop. Ten I lived with these incapacitating herpes outbreaks until a new GP prescribed Vitamin D supplements when I was aged 70. Since then I have not been troubled by oral herpes.
I experienced some osteomalacia a year ago, not a serious case but I was having a lot of muscle and bone pain and various other issues, my GP couldn't figure it out. I started researching it myself and thought I'd try a daily dose of 1000IU of vitamin D3, and wow I felt so much better.
Their research are so outdated. I cannot stop rolling my eyes. I didn’t hear that they even mentioned D3 + K2. How can any reasonable doctor not mention that? They focused on Calcium And D3, which most sensible doctors don’t prescribe anymore. They didn’t mention the effects of D3 for inflammation. Most people are so inflamed and VD is so crucial for their health to lower inflammation risks! stop fixating about fractures and bone health. I am so disappointed Zoe let this happen.
My VitD levels were always borderline critical (low) over various years, and no GP ever suggested supplementing. I also had incredibly low anti-mullerian hormone (linked to fertility). After starting to take Healthspan Vitamin D supplements. My anti-mullerian hormone levels increased significantly, even though I was years older. And I fell pregnant, and the paediatrian that managed my pregnancy was really impressed by my VitD levels (which had significantly increased). So I feel I have evidence that the supplements helped me in a profound way.
As for calcium, he should have explained that it's calcium CARBONATE that is bad to take since it's pretty much just ingesting rocks. The citrate form is way better, but never take more than a couple hundred mg's a day.
The same bad calcium carbonate that is used to fortify almost every plant 'milk' and other food that has 'added calcium'. I'll stick with eating a few fermented dairy products that don't have added calcium. 👍
