which B12 to take, what is the latest? Some B12 activated pills (these dissolve in the mouth) come in a massive 5000 mcg form, can these pills be safely taken, once per week? Thank you.
I'm neither a vegetarian or vegan 😮(and healthy) but my partner is a Vegan. With a daily supplement of B12, her lab values came back Higher than normal (a false positive?). She now takes a B12 tablet 3x a week (not everyday ). She seems healthy but I think she needs more of a "whole food" not processed Vegan diet. Maybe we'll repeat her lab values just to see the difference of a 3x a week B12 supplement.
I worry about those people on a processed vegan diet. Processed food is junk food, and that's going to lead to serious health consequences.
I would also recommend supplementing with potassium iodide if eating a pound of cruciferous vegetables a day.

I bought 10,000 iud b12 supplement, does anyone know why someone would want to take that much. I split it in quarters and took 2,500 yesterday. Should I do that then every week or should I take smaller doses everyday?
I’d like to understand if there is any difference between the sublingual dose recommendation and B12 injections. I’ve tried some popular sublinguals but they don’t seem to have the same absorption as the injections. I am currently on 1000mls per week and curious if I should double that to meet the 2000mcg standard recommendation…thanks for any insight.
Doctors usually only do injections if you are highly deficient.
If you take a hight quality oral B12 you absorb part of it already in the mounth (don't drink before and after so it will mix with your saliva and has time to absorb.
If you are not sure if you take enough get your levels checked
other that animal products aslo not low B12 dose supplements can be cancerogenic and WITHOUT show benefit for general popolation at risk

@NutritionFactsOrg thanks for the update I was just considering switching to daily doses this is great! Also is there a limit to how much B12 we should get? I was considering farming my own water lentils aka duckweed for my B12 instead of supplements which is segmenting into a VERY LARGE market of all sorts of applications so expect to get this question a lot soon because I had read that duckweed is actually a plant-based source of B12, is that true do you think or does the duckweed just not get cleaned off before it hits the market?

@@MdoubleHB "Cooking destroys the food and most nutrients in it" is not correct. Cooking, especially overcooking as my mother does, indeed destroys some nutrients. But cooking releases some nutrients so they can be bio-available. It it thought that the discovery of cooking and the resulting improvements to human health led to our larger brains and success as a species.

Very unfortunate for you.
He didn't state it, but if you read the Optimum Nutrition Recommendations at minute 10:05 in the video, it says, "Those over 65 years of age should take at least 1,000 mcg (ug) cyanocobalamin every day." That's a LOT different than taking 50 micrograms daily. I think that should have been stated and explained........That seems like a very high daily dose, especially considering the RDA of 2.4 micrograms per day. I was taking that dose and my primary care doc asked me to stop taking B12, because my serum B12 was very high, even though I did not take it for several days prior to the blood test.
good stop.

@MdoubleHB I see you've made this exact comment before, which begs the question: whom are you trying to convince, "humanity" or yourself?
And are you seriously able to say that you do not cook any food? I find that extremely hard to believe. If you're eating strictly fruit and most vegetables, okay, I can swallow that, but whole grains? Coffee? Beans and legumes? Come now, seriously?
@@Danuxsy Someone wasn't paying attention....you need 50 a day or 2000 a week.
The ones I have are 500 so 4 tablets once a week?!!! And im 60
Within months of treatment they made a remarkable recovery even though they showed they had proper levels in the first place -- then our tests are wrong or our idea of optimal levels are wrong or there was something else changed, right? I would not automatically assume throwing B12 at it was what made the improvement and would instead be asking questions to see what else changed

They wont because that would go against there " everyone should eat plant based" theory. Obviously as humans we need b12 from animals, cyano is the version in vegan supplements and it contains cyanide. Never have we, as humans, needed supplements until now. In a time where the amount of saturated fats in the American diet has gone down dramatically, and rates of chronic illness have gone up dramatically, how could anyone believe these studies?

For an incomprehensible reason my comment about vitamin B12 is only visible, when you order the comments by "Newest first".
So do that now and read it.
@@MdoubleHB I read that comment prior to my post. I need to supplement B12 (blood test results), hence my question about lab tested B12 supplements that are affordable and easy to order in Europe.
In all honesty,this doesn’t make much sense to me. Why 50mcg/d or 2000mcg/w?
The difference between 350mcg (7*50) and 2000 is huge. Can someone explain it please? 😅
Absorption rates diminish the higher you dose
Great video - but I'm still confused. My blood tests showed I had a huge amount of B-12 'stored in my liver." So I stopped supplementing for six months and restarted but "only" taking one 5000 mcg capsule each Monday. OK, so I can reduce that to 2,000 mcg, but what's the harm in too much B-12?
dont stop it for half a year wth bruh
@@dimitrisskar4174 As Dr. Greger said, it takes a while to show symptoms of insufficient B-12. Testing showed I had a huge amount stored in my liver - so I might have coasted without any B-12 supplementation for a year, or longer. But after six months I resumed supplementing B-12, but only once a week instead of daily (as I previously did.) It would be interesting to test again and learn my present B-12 level. My question is, "will excess B-12 cause any problems?"
It's a simple Google search to find side effects of taking too much B12 and how much is too much. All vitamins have harmful side effects if you take too much, but you also have to check how much is too much for each vitamin.
@@larrymaloney877
i was talking in the logic of better safe than sorry
@@trapezius77 not so "simple." A Google search also shows how harmful a whole food, plant-based diet is. Another simple search shows the benefits of KETO. I prefer to learn here, from Dr. Greger.
Why is a singe higher dose per week good enough? Why wouldn't we need some B12 daily? Also, this talks mainly about "single daily dose". Why not multiple smaller doses per day? Finally, why does the recommendation suddenly shoot up to 1000 mcg daily at age 65? I'm 60 and "only" get 100 mcg cyanoco- + 80 mcg methylco- , in two separate supplements roughly 6 hours apart.
What are the foods again that can be eaten on a regular basis to get those recommended levels. Thanks
You could have about 1 ounce or around 40 calories of clams per week and you would get about 1000% RDA of B12.
@@MdoubleHB humans are omnivores. This means that we can eat and digest both plant and animal matter. We have the anatomical features of both herbivores and carnivores, such as flat molars for grinding plants and sharp canines for tearing meat. We also have a digestive system that is capable of breaking down both plant and animal proteins. We thrive best by eating what our ancestors ate that includes meat.
@christianthomsen7046 our ancestors died by 30-50 from what are now known as preventable diseases, usually the form of different cardiovascular and degenerative diseases. Old ways aren't always superior. And no, we don't have sharp canines.

Interesting video on a very important subject. I have one observation to make: it seems that doctors believe we're all exactly the same, with bodies that behave in precisely the same manner. This is not true. My wife was told she needed 2.4 mcg B12 daily until she hit age 65. Suddenly, on her birthday, her doctor told her that her body now needed 1000 mcg per day! Something had happened overnight, apparently, that dramatically reduced her body's ability to absorb this vitamin (no, no lab tests had been done). I'm sure you see the nonsensical nature of this belief that the human body behaves like this in a clockwork manner. My wife did up her daily intake, but only to 250 mcg, because high doses taken without clear medical indication can lead to blood clots.
You could have 1 ounce of clams per week for 40 calories and get 1000% RDA of B12 that is absorbable in the proper way. This way you do not have to rely on an unknown unregulated supplement in a bottle made in a factory you never visited, that the body may view as an unknown foreign enemy that it does not recognize or welcome.
i'll stick with the 2500mcg, l have, per week.

This is called species-specific diet.
It is the most important thing to understand for humanity right now.
Cooking destroys the food and most nutrients in it.
This should be common knowledge by now.
But the masses are still very ignorant and they are constantly distracted by nonsense.
It is the reason, why we still live in the dark ages.
To have paradise on Earth, humanity must adopt the species-specific diet.

I absolutely love, love, love Indian food!!!!!
Indian diet is very unhealthy
My husband's blood test results showed his B-12 to be over 7,000, so the doctor has taken him off of the supplement for now. He is experiencing balance issues, numbness in his legs, and dizziness, so the testing was to try to determine what might be causing these things. She doesn't think that the high B-12 is the issue. Does anyone know what the effects of way too much B-12 can be?
Well, my wife once had deep vein thromboses (blood clots) after minor foot surgery. We were warned that excess B12 can lead to blood clots, so more is not better. How much is too much? I'm not sure anyone can say.
Excess B12 is just peed out..
My doctor put me on 1000 daily 1 y after blood test showed 14000 , meaning 20x more than normal level he took me off and I am worried I am supposed to take a blood test in 3 m
50 a day... So the leading b12 supplement (veg-1) is not enough? Odd.
@@MdoubleHBjust like that poor fruigivore who died last week of malnutrition? Why dont you go look up how it takes 12 grams of vitamin k1 (plants only), to make 1 gram of k2 (animal foods only) in the human body. You know nothing about nutrition and are a danger to yourself and others

Imagine confusing your opinion with reality.
Intelligent people do not have opinions.
You are obviously not one of them.
Very unfortunate for you.

Go to the nearest wood chipper.
Then jump into it.
Vitamin B12 is produced by bacteria in the body.
People only have to supplement vitamin B12 in very rare cases, when something is wrong in their body.
Watch Douglas Graham and Loren Lockman for proper information about vitamin B12 and about health and nutrition in general.
@@MdoubleHB you are the one that's confused. What you just said proves that you are totally incapable of seeing any perspective other than your own. Totally closed minded and dogmatic, when you get confronted with evidence that goes against your belief you ignore it and become more steadfast in that belief. no one should give any credit to what you're saying because you are unable to prove anyone wrong who goes against it. You simply call it their opinion and assume it's wrong. Ironically this is all based off of your own personal opinions. Its actually pretty interesting!
Do you think it would be nice if at the end there would be a one minute summary and tell us exactly and specifically what we should do?
Too much b12 breaks me out. How do I know how much to spray in the mouth😢
I switched to a supplement that doesn't have cyanocobalamin. Mine has methylcobalamin & hydroxocobalamin. You could do methycobalamin + adenosylcobalamin. Or you could do hydroxocobalamin alone. Cyanocobalamin turns into cyanide in your body and gives you acne. The others are natural and don't have this problem, thus they don't cause acne.
adenosylcobalamin makes me jittery and nervous, so I don't like it personally. Anyway, that's my experience, I'm not a doctor or making medical advice, but I hope the info I provided can be helpful in your research :)
Red meat, dairy, eggs, fish, all what we need to survive, no one ever got enough b12 from water that is ridiculous if you measure b12 amounts in fresh water steams you would need so many gallons you'd die
@@mountainstream8351 even if you eat nothing but dirty potatoes your still only eating like and ounce of dirt day. I doubt that's enough and unless you cultivate potatoes, that's not even possible to do. So what did humans eat dirty fruit? Did they rub dirt on the fruit? No they ate primarily red meat and were healthier than your avarage person today by far

@@oraziohall2969 Damn I must be dead after 30 years of no flesh (meat was a word that meant all food), dairy, eggs (chicken menstruation, ewww). doc and folks think I present about 10 years younger than I am. Kid has been vegan from birth and is not dead and is not unhealthy (according to doc and bloodwork).
There are also thousands upon thousands, over 20,000 - of edible plants and currently we consume very little of the number. Recently it has been found that duck weed has b-12.
The b-12 is a bacteria it was in the ground and in the water.
Can a single dose of 5000 be taken every other week or should it be weekly or daily?
Gorillas are smart to know they can get B12 from poop.
If y'all don't want to become irritated or see bullying, I suggest y'all don't read the comments today. 😢
FACT!!! They definitely got me on my soap box! I think I must quit now. LOL
@@marygatdula2744 There's at least one insane person on there. 🤣😅🤣😅🤣😅🤣 Geeeeeeeesh. How funny. I understand the soap box, but it doesn't seem we can all be civil on her... for Dr. Greger, I mean, can ya get any nicer? Lolol wowzer.
The subject is confusing. More and more videos krep coming out on it: i thought 50mcg per day or 2500/2000 per week, or 1000mcg per day over age 65. I am in that age bracket: should i take 2500 per week or 1000 per day?
I do 2400 ug a day better you oral spray
Since people who aren't on a plant-based diet are also found "in the wild" to be deficient in B-12, why only recommend the supplement for people on a plant-based diet?
do not think he replies to comments.
but i would say that why waste stuff on the problem people. they have to quit eating animals product first and foremost.
50mcg/day? The Bragg nutritional yeast label says 1 serving (2 Tbs) contains 15mcg B12, which is supposedly 630% of the Daily Value. To get 50mcg I would need to eat over 6 Tbs per day. That doesn't seem right.
Is there anyway you could explain this without the annoying hammy overacting
Another TH-camr who puts up a description and then makes you listen to him talk because he likes to hear himself talk before he will ever tell you what The answer is to the description.. Do you enjoy the sound of your own voice? I ended up clickng him off I never got the answer.
Lol.same here. Trying to hard to be funny to give the pill.
You click off, and YOU are the loser. Dr Michael Greger's expertise and efforts on many levels helped millions of people improve their health and quality of life. . . including mine. He has my utmost respect and gratitude.
GOD PUT ADAM AND EVE
on a plant based diet
Religion has no place in science, especially in nutrition. If you want to eat like Adam and Eve, go see how that works out for you, maybe you’ll learn your lesson the hard way.
@@Yasqo sorry I'm not religious
Sometimes the history lessons and pontification insights are fun but sometimes they get in the way of people seeing the relevant data and actual recommendations. 🤦
I solved it, I eat tuna & sardines.
animal products are harmfull and devaste enviromental other that full mercury
All this did was change me from vegan to vegetarian. Too much math, when I can eat an egg.
