What Does A High B12 Level Mean?

- Why you might have high b12 levels, what does high b12 level mean, and is a high b12 level dangerous. There are three main scenarios that I'm going to discuss. I will briefly mention them here: number one is improper testing, number two is has to do with cell membranes and transportation and number three has to do with liver disease.
MY NEW B12 BOOK: geni.us/rTQTvd (Amazon)
Cell membranes Support geni.us/RhaqAz (affiliate link)
Cell membranes Support geni.us/64DQ5 (Affiliate link)
Omega 3 geni.us/eBDLI (Affiliate link)
If you want to find out a little bit more details on what each of these mean and why it could be contributing to your high b12 levels keep following. what does a high b12 level mean is it dangerous what's going on here we're gonna get into the details of all that but first off it's not really dangerous to have high b12 level in and of itself but you should be looking a little further into why it could be happening and in this video I'll discuss the three things that most likely are causing it and these are the most common that I see in my practice okay the scenario number one is testing when you’re doing a b12 test typically it's a serum b12 test and the ranges go from about three hundred or two to fifty two thousand or and if you are taking b12on a regular basis in any form and it’s absorbing into your body it's gonna raise that serum level when you're doing your draw if you took b12 when you’re close to the test you usually want to give a couple days washout period up to five days probably maximum would be well not maximum but that would usually be good timeframe you could wait longer it’s kind of see what's going on if you have like a really high b12level you may want to not take any for like three weeks and see what happens if you've been off of b12 for a really long time and you're still getting a spike then that's gonna you need to look at scenario number two and three a little bit more on testing the other is of course injections are gonna raise yours here and level a lot more than just an oral tablet also depends the dose of your tablet the dose of the injection etc. but for getting an injection you want to have off probably a little bit longer but washout period probably seven days at least and then how often you're getting that injection etc. will dictate you know what the likely rise or high end of that b12 would be I'm seeing them as high as six thousand I've seen them you know as low as like a hundred or less but in terms of testing you do want to have a washout period when you're testing your serum levels this is really the only test on a standard lab that there is available is this serumb12 level there's no intracellular b12level test through standard labs and then other vitamins too can interfere with the b12 assay specifically by it in you want to make sure you're not taking any biotin in close proximity to the Tuda test that's scenario one in proper testing can lead to IV 12 levels and in the case that it's that's the reason and there's really nothing else to worry about you can even the high level itself isn't really problematic it might not be helping as much as you think but it could be some people just need to run at higher b12 level to get it into the body into all the tissues that's a scenario number one. Reason number two for why your b12 is higher what does it mean is relating to cell membranes and transportation of b12 when your b12 level is really high it could be that you don't hear enough your body's not making proper transport mechanisms for your b12 and this is just a carrier protein all things in our bodies almost everything needs to be transported on carrier proteins and b12 is one of those in our genetic alterations that basically won't allow you to make sufficient amounts of these carrier proteins which will lead to basically it's not getting distributed throughout your body the way that it should and the same thing goes to once it arrives at the cell it has to get transported inside and that has to do more with cell membranes andor if your cell membranes are fragile or you're not repairing them properly that can also lead to higher b12 levels and serum because it's basically just floating in the serum and then it's not getting excreted out of the box or getting into the cells and then it will eventually get excreted out of the body but it's not actually kind of trading into the tissues the way that it should and there's also genetic alterations in both the carrier protein it's called TCN trans cobalamin and also the cell membranes which is of phosphatidyl ethanolamine methyl transferase enzyme can be altered which leads to instability and cell membranes or poor production of cell membranes both of those scenarios can lead to higher v12volts.
Just wanted to share that this may help someone not too panic if you get high b-12 results.
last week I was tested for b-12 and mine was above 2000. I was taking b-12 supplements, but didn’t think it should get that high.
I decided retest 2 days after i stopped taking supplements and the test came down and was within the range.
So if you take b-12 supplements and get high b-12 results, stop taking it and retake a test. Some suggest wait 2 weeks, but mine fell into range after two day. Hope it helps
Thank you for sharing that. That has been my experience with patients as well
MG, Glad to hear this. Mine was over 2000 last Monday when I did my bloodwork. My Dr said to be careful of the under the tongue B 12 which I was taking daily and go with only one per week. My pre test before the addition of B-12 was on the lower side but not severe so I'll follow my Dr's advice..
I don't take vitamins, or biotin, eat meat, or consume alcohol. For the last few years, my B12 was high. I was not warned of any potential danger. Unfortunately, today, I found out after suffering much pain in my stomach, and kidneys and having other symptoms such as fatigue that I suffer from leukemia and kidney and liver problems. I think this should be taken more seriously so that people could understand that there are potential dangers in having high B12 in the blood. I wish I had someone or a doctor tell me that I was running a risk of all this. I am not old and I feel like I have no life in me. Little by little this has destroyed my life and I fear for the lack of knowledge other patients facing the same situation may have. Maybe, you should make a video about the potential outcome of high B12 in the blood. It would save lives.
Thanks for sharing! I m working on a book dedicated to high B12 but could do a video on the dangers. I do go into this in some of the videos but may do another one on dangers.
This is exactly what my doctors think is going on with me! I’m having a liver scan soon also, i was never aware leukaemia could be with liver!! Not enough known about it
My doctor just called me and told me my b 12 is a bit high. I should lay off the engery drinks. However I do not drink those drinks. I don't eat any sugar nothing but eggs and meat with butter
Hi. I'm a 51 year old woman. My nurse practioner I see ordered blood work. My b 12 is over 2000. 2 years ago.it was 236. Since it was low the had me b 12 injections for 5 months. I have not been on any supplements. I'm having the test repeated but she said could be a liver problem or cancer. My liver function blood work was normal. So was my cbc
@@danajacobs9097 eggs are high in b12
Love your video! It is so informative and also unlike the articles I just read, does not jump to the conclusion that you have some horrible disease as the most likely cause. :D I do supplement-1000mcg. Maybe I shouldn't. I am reading about all the high b12 foods and I eat sardines 1X week, can of tuna plain 1X week, salmon 1 week, 2 eggs daily, cheese and greek yogurt daily, grass-fed beef 3X week. Whew. Didn't know I was actually getting so much in my diet. I do eat TONS of healthy veggies too! I did get several B12 shots about 3 months ago, but that should have worn off. I will try skipping the supplement and retest in a few weeks. THANK YOU for taking the time and explaining this.
One other note, my supplement says Methyl B complete. (featuring patented quatrefolic 5-MTHF. ) Includes 25mg Riboflavin, vit B6 15mg, Folate 2000mcg, B12 1000mcg, and trimethylglycine 650mg.
Hi Diane, I did not see a direct question but maybe you are wondering if you need to take b12 or b vitamins in general? While most people will benefit from periodic supplementation, not everyone needs to take a b vitamin supplement every day.
A few months ago my b12 levels was high 1200 this was because I was on multi vitamins with b12 250up with a ri 10,000% I was terrified cause I Googled what it could mean and what I found was not good. Got re tested and now my b12 level is at 600. So like he said in the video if u r taking any vitamins/ supplements with more than the daily recommended level this can make your b12 levels increase.
Thanks for sharing
what are the daily recommendations?
That's exactly what happened to me.
Same thing has happened to me because of supplements, I stopped it and proceeded to naturally taking it
Common sense
Hi Doc. I have b12 levels of 1190. I don't take supplements. In 2020, it was at 400. I also have low neutrophils at 1.2, Serum inorganic phosphate at 1.57 mmol and MCHC at 353 g/L.
RBC is a tiny bit out of range along with Creatinine and Potassium.
Is this normal?
This is a good video. I'm not finding a diagnosis online by any shot, but am openly looking for thoughts on my B12 levels. I've not yet been given the full results yet, but have had terrible head pains and went to the doctor. Had blood tests taken and I was told that my B12 levels were borderline. I'm a man in his mind twenties, healthy, walks regularly (sometimes 12k steps a day), pushes weights (usually 40 kg) and enjoy cooking healthily. My whole family are like me in terms of cooking and I've grown up eating lots of vegetables and have continued that in adulthood. I had been taking multivitamins whenever I had a full day ahead of me but stopped before going home for Xmas this year. I had thought that the B12 levels could be linked to the head pains, but I now don't think so after taking vertigo medication and now believe that the levels are due to multivitamins. Bit of a wake up call because if it is vitamin supplements there is clearly some danger in taking them daily in phases (intermittently basically). I really welcome some thoughts on this because I'm not a heavy drinker by any means and would usually only have one beer every couple of weeks or so.
Neither high or low b12 cause head pain. Sometimes taking b12 can give people headaches but the high levels of b12 in the blood does not cause this
my vit b12 level is elevated at 1177..i am thalassemia minor and taking folic acid 5mg tablets for past 4 months on doc recommendation.But ,for last few days, I am feeling tired, dizzy and brain foggy, also have a 3.5mm kidney stone.Complete blood counts are normal except eosinophils(6.2%) ..low urea ( 18mg/DL) and MILDLY ENLARGED LIVER on ultrasound..mild right abdominal discomfort for past few days and mild body itch. Liver function tests, creatinine are normal
Could it be because of LIVER DAMAGE, LEUKEMIA ,KIDNEY DISEASE or folic acid supplement for past 4 months...i am afraid..please reply
I had low levels of vitamin B12 I was given shots now my levels are at 2000 and something. I feel dizzy, I have a headache everyday, vomitong nausea, brain fog. I have hashimotos disease but my TSH levels are good now, all my bloods are ok except my B12. It was about a month ago I had a shot. When will my levels come down?
Another they will be lower
@@swintegrative another month you think? TIA
You are by far one of the best doctor! You seem kind and and helpful and with knowledge. Thanks for all the information 🙏🏼❤️
Thank you
Hi, I had delivered baby 3 months ago..During pregnancy it was on range around 600 but now its around 1400..I am breastfeeding my child so I am taking Iron and calcium only...What could be the reason of high b12
I know this is old but I came across this video doing some research on my high B12 readings I got today. You mentioned biotin and it clicked, I have been taking biotin chews. I’m a little less worried now. Thank you for this video.
No problem. Thanks for your comments.
Same with me! I read in the high 1,900 and I am also taking 30k mcg. I feel a lot better.
I am taking biotin too.
I took too much... been avoiding it since.. terrified of what it's doing to much.. been drinking a lot of water trying to flush it.. i hear it leaves in the urine.
@southwest Integrative Medicine Hi Doc, loved your video. Question, is it okay to inject my b12 in my stomach ? I’ve seen videos that say okay but someone said their doctor says not okay. What’s your opinion ?
Generally done IM. Some of my patients do it subQ without any issues.
Personally, it never increased my B12 levels when I injected it into the stomach.
My b12 levels have been over 2000 for 6 years, my active b12 is over 2000 as well. My b12 binding capacity is 364 which is low , I have all the symptoms of b12 deficiency, burning feet and hands,joint pain , weight loss , hyperpigmentation, muscle wasting and pain, headaches . My ferritin levels are also very high . My liver is mildly enlarged and I have biatrial enlargement too. Doctors have been of absolutely no help, I’m at a loss. I have autoimmune gastritis unfortunately. What can I do if anything?
I'm on a ketogenic diet, eating healthy foods, and exercising. My B-12 level is (968 pg/ml). Doctor, is that number harmful. I admire your composure and lack of hasty judgment. I wish every doctor was like you. Stranger still, my hemoglobin and iron levels are low. I appreciate your generosity and reassuring demeanor. New sub.
High B12 is not harmful. When it is high for no reason it can be a signal that something is wrong. Your level looks normal.
@@swintegrative thank you for your reply and assurance.
How are you doing now?
@@kellymcdonell9687 . fantastic, and I found that the good bacteria I'm taking is the source of my elevated B12. I discovered that the component had 700% vitamin B12. I changed how often I took my probiotics from once a day to once every four days.
My mom is suffering from sever anesthesia in her foot fingers. She had diabetes and treating with b comlex and b12 injections. Is it likely the cause of anesthesia is the increase of b12 level, because the numbness has increased after injections?
I’ve had 2 b12 tests done, the last one was 1 week after a b12 injection. Looking back at my blood work over the past 6 months, my bilirubin was very slightly elevated and my liver enzymes very slightly but my doctor considered them normal. All of the readings are connected correct? I’ve had 8 plus months of bodily symptoms with no answers. Any feedback would be great!
Hi Catherine, bilirubin is not always correlated with liver enzymes, sometimes it is. Vitamin B12 will not cause elevated liver or bilirubin.
thank you for the very interesting video, am looking forward for the next one, as i have high b12 >1476, and it seems the doctor here do not know about this case (blood test all normal except high b12, also live and kidney blood test was normal), i used to supplement multi with high b12 (methylcobalamine ) but i cut off 1 month before the test and followed a normal diet with low meat intake. any ideas what to do next? thanks from the Middle east
Hi Hadi, glad u liked it. Yes the next video will be out soon with ideas on what to do.
Hey , my case is the same as yours , what was your followup ...are the levels normal now?
Same as me, not sure what it shows
@@レモン-e2h
Same for me too! I have high b12 > 2000 right now. I checked one month ago while supplementing and it was ~1500 so i stopped supplements. Now, I don't take supplements, but I did take some nutritional yeast (only 750% RDA a couple hrs before the test I think)
I’m the same?
great video! how do you fix the cell membranes?
Thank you! Supporting cell membranes with fatty acids and phospholipids and the latter being more important. Something like this could help geni.us/RhaqAz (affiliate link)
@@swintegrative thanks! i do take PC already, but i think genetically i have issues accessing it - have you ever come across that issue before? i do eat eggs, but i dont think its enough and i find supplements dont typically help much this this issue- cell membranes are super imporatant, is there any other fatty acid you recommend?
My B12 was 200 my FP started giving me injections. And now it’s 1500 , and I am pre-diabetes. I’m not sure what to do she said in 3 months I’d need to go on meds. . Should I get a sec opinion? I changed my diet. I’m 60 and have never had sugar issues
Don’t see how b12 injections are related to blood sugar issues
Had my b12 tested and was 1245. Been supplementing 3000mcg for 5 months. Makes since!
Yes it does
Thanks for your explanation
I was taking biotin for months but I stopped since 2 months.
Today I was doing some blood test
And my vitamin b12 is 1046 and I’m taking magnesium supplement
Is this level 1046 considered as high??
Hello firstly I would like to say thx for ur responses. I got recent labs the other day my b12 is higher 2k my alt is 60. I’m going to ask for a Methylcobalamin test. Do you know of any correlation with b12 n alt
hi Donajor8, yes alt is liver function test. The liver cells store some B12, so the high B12 could be coming from the liver. It's always important to re-check and verify the lab values bc your body is always in a state of change. I think you mean get methylmalonic acid test not methylcobalmin.
@@swintegrative yes there the test my liver and b12 been high since my unknown chronic illness I had a liver us a few year back. It was ok . What test u suggest for mycotoxins
For internally generated great plains is a good one. For environmental testing www.mycometrics.com/index.html is a good company but don't have as much experience w them.
TINGLING, NUMBNESS, BURNING AND SLIGHT PAIN PROBABLY DUE TO “overdose” of b12: I supplemented with b12 without checking my levels first and took more than I should have. My levels were afterwards at 2000 and i stopped taking it. About 20 days later i began experiencing tingling, itching, numbness and some burning sensation on my left foot. Now my levels have gone down to 850. The neurologist said, although not sure, that i might have been caused due to the “overdose” of b12. I have been feeling this for a month. Anyone out there with the same issue?
Yes!!! Though I'm not totally sure of my levels right now. Previously 1807 and being monitored, I'm getting a tingling/burning sensation tips of toes and tips of fingers, but didn't associate the 2, l thought it may be some kind of nerve thing? I'll definitely be looking it up... Do you have tummy issues by any chance?
@@baileysice2715 Hi. I apologize if my reply shows up twice, apparently youtube did not save it. No, I havent had any tummy issues. However, my symptoms have been active for around 5 weeks. I have a second appointment with the neurologist tomorrow and will let you know. Are you ok with us keeping in touch to help each other? All the best to you.
@@sergioduque9050 Yes, most definitely keep in touch, good luck for tomorrow.
I don't think high B12 causes numbness and tingling. There are other reasons B12 can do this (in some cases) but not from it being high.
@@swintegrative thanks for your reply. I cant find the link now but i found an article with a forum like option at the bottom where a few people complain about these symptoms and there is also info of this sort on the web once you dive in researching. I made a post here in case I find someone here with a similar issue and find out its outcome. Thanks for reading Southwest integrative medicine.
My B12 is high 1550 after one injection and take some B12 supplement, I'm so thin ...now i don't know should İ stopped eating food contains vitamin B12? İf yes so what should i eat...my main food is egg...? Thank you for a great info❤
Hello Dr, Im on keto, have been for years and feeling amazing but my last blood panel all was normal but my B12 was 1475. I am fit, weight lifter post menopausal. Should I be alarmed?
Hi Doctor, I’m glad I found your channel. I need help PLEASE. I did my blood tests yesterday but it was very strange. I had hight b12 like 1300, high ALT and AST and deficiency in vitamin D but everything else is normal. It got me worried because I workout 6 days a week and I usually eat healthy so I don’t know what’s happening? 🤷♂️
My latest B12 number is 1720. I do not take any supplements with B12 in them. I do eat beef, eggs, fish, chicken.
I used to have NAFLD but my liver panel is completely normal over the last 2 years.
Would 500mg of Choline supplement help lower the B12 level? But the 2-3 whole eggs I eat daily have choline already.
Thanks.
I’m healthy 63 years old female on ketogenic diet, my vitamin B12 is 1269 I’m not supplementing B12 vitamin , should I be worried of hi level of vitamin B12??
Hard to say for your specific situation each person has many different variables going on. For instance did u use to take b12 and now u stoped for 1 month? Do u have other chronic health issues? Do u just have one test showing high or multiple? These r just a few considerations.
I only take a multivitamin and my b12 is high. I cut back to taking it every other day but I feel so much better when I take it everyday. My Dr said to stop taking it all together but he wouldn’t do any other blood tests. Another Dr I have said don’t worry about high levels at all. So frustrating you have to take your health in your own hands!
I don’t think it’s harmful
Thank u so much for ur detailed video
My blood test showed 628
Is this low?or high?
I also have nausea and burning sensation and hard to digest the protein
Did 2 endoscopy
Ct scan
Barium test
They couldn’t find anything
It’s very frustrating
Is it related to b12 level ?
Ur respond is appropriated
Can taking B1 vitamin and eating lots of oatmeal and tuna cause your B12 to be elevated please? I have been taking B1 and Benfotiamine. I am trying to see if there’s a correlation between those 3.
No don’t think so
If the cause is scenario number 2, what do you advise?
do you mean from a cell membrane issue/poor absorption into the cell? That is tricky bc there are a few reasons that can happen. If it is strictly the cell membrane and nothing else phospholipids should help. My other videos and book maybe helpful for you.
Hi doc ..my mom was having b12 from past 18 to 20 days and now when we got tested it was 1980. So if there's something to worry about.or it can be cured by having plenty of water and by controlling diet.. please share the answer asap doc..
My vit b12 level was 1035, wbc all normal and folate and ferritin . I take vit b12 daily and n complex . I switched forms from methylcobalamin to cyanocobalamin in the past month . 1000mcg Daliy . Should I worry?
My B12 levels are over 2000 I don’t take supplements or anything why is this and what can I do?
Hi Chris there are a few more videos on high B12 that answer these questions. My new book goes into a lot of detail on this too amzn.to/3upWGnd
Thanks for this straight forward information.
Your welcome Cheryl!
Hello doctor my B12 is 958ng is it something to worry about please, .Been informed it is not something to be concerned about .please advise

Having a f/u with family physician soon.
could be the MTV
Thank you for your response. Much appreciated!
Does it reduce Now ?
Thank you for the information 🙏 💖 What about high b 12 for kids who never take vitamin supplements . Could it be sign of any sickness ?
I’m not as familiar with pediatric references ranges but I believe it is the same situation.

THANKS
Hey doctor. Using B12 1400 mg per day for 1 year. Tested B12 today with regular blood work was normal except B12 was about 200 elevated was 850 and normal range is maximum 650 pmol/l. If I stopped the supplement, will the level decrease by it self or I have to stop eating certain food though to lower it?
Usually goes down on its own.
@Southwest Integrative Medicine thx I use high dose of B12 1500 mg per day since 1 year for nerve pain. Now stopped taking any B12 since one month but that doesn't help nerve pain Any safe dose to take without side effects and without increasing my level? My last time was 850 pmol/l. Normal range lab reference maxi 650 pmol/l
My vit b12 level is 909 and my Red cell distribution width is abnormal 15.2 what does that mean?
Hi. I have a serum B12 level of 745 ng/l and a monocyte count of 0.8 10*9/L I have been experiencing pain all over the body, arms, legs, chest (which feels like not enough blood/oxygen is being supplied) Based on my blood work, do you think that is something of concern? I would really appreciate the advice.
I don't think your b12 levels have anything to do with your symptoms, since it is in a normal range. I would need a lot more information to be able to help you find out what might be causing those symptoms. The "pain al over body" is a concern and should be evaluated with a face to face visit with a doctor. I can say that the b12 level you report seems normal.
I have high B12 Kobalamin i train and i eat a meat every day as cheese eggs and more of thoose nutrition is it something to do with it ?
Thank you for educating us
your welcome!
My B12 Level is 1159. Low HB though. I’m not sure why it’s so high. I take iron supplements twice a day with 1000 mcg. Can that be the reason? I’m worried for it to be something dangerous
Not likely from taking iron unless it has B12 in it. Sometimes it’s just genetic and not a real problem.
hi there, you mentioned no. 3 cause which is the liver.. i have high liver enzymes.. what should i do? please help. 😢
alanine aminotransferase 130
AST 65
GGT 125
B12 1058
🤔
Everything was good in my blood test but I have a 849 b12 level which is higher than my doctor would like so he called me in. I have been supplementing B12, but I’ve had other symptoms that predate that so I’m a bit worried.
Likely from supplementation
I am glad I found your Dr. I have not taken B-12 for over 9 months ( did not know Biotin,which will stop). It has increased during this time to 1383. I do not drink enough water to avoid interrupting sleep for a bathroom use. I have been watching my diet and do eat a high fat ( nuts, fruits, vegetables salmon cod meats pork) and hopefully not causing any liver damage. I walk 2-4 miles/ day and stay very active. Any suggestions?
Nothing stands out but you might want to get my book that goes into more details.
Hope you are doing well now facing same problem
I had bloodwork done during my physical this week and my B12 was elevated to 1383 pg/ml. It did freak me out a bit since my levels had always been normal. But listening to you made me realize I had taken a methylated Multivitamin and a methylated B complex when I got up that day so of course my serum levels would be elevated.
I have been searching in medical journals to find any studies done on dosage in B12 shots and how they correlate with blood B12 levels. Are you aware of any such studies? Mostly I am curious how one B12 injection could affect blood B12 levels, etc.
I have come across this information in medical journals. Look through the articles posted in the descriptions of the high b12 videos. It may be there.
I have seen this information in medical journals. Look through the articles posted in the descriptions of the high b12 videos.
If one only ever had two vitamin B12 injections with no multi-vitamin use and B12 levels of 1,400 pmol on a blood test taken about two weeks after one of these injections, how long could one expect these levels to come back down? Would one see these go down to, say, half after three months of no vitamin B12 intake?
maybe not half but they would come down for sure if everything else is normal.
Thanks so much! Your channel is definitely the most informative on this topic. Went through all the referenced journal articles in one of the links.
i was told my B12 is high because of nuts i did not hear u mention it
as i was reading other comments i realize my multivitamin has B12 100mg per caps and also biotin
any clarification here please
thanks ahead
No nuts are not a high source of b12. MTV can spike it though.
@@swintegrative i am so grateful thx for the quick reply
i will stop the MTV and retake the test in 3 month to compare the result
thx a again
Hi, doctor my b12 was 2800 before two months now I retest it and it gets normal 850 with out taking any drugs . I really worry if it decreases another time, and worry about the reason behind it.
Hi there, thanks for the questions. I think it is normal for vitamin levels to fluctuate. It could be something as simple as consuming something rich in b12 before the first test and not in the second. Most of the time when B12 levels are low it is from low consumption/ intake from food.
Hey doctor!! I mistakenly took around 1500mcg drops of methylcobalamin B12 2 weeks ago. I have really had bad symptoms since then, like liver pain, stomach pain, insomnia, shortness of breath, chest pain, severe diarrhea, weight loss... Yesterday I did my blood test and surprisingly it came low on B12. I still have severe insomnia, shortness of breath and some diarrhea. What should I do with this issue? Please advice. Thank you!!
Hi The Snugs, I can't give you specific advise or treatments. However it does not look like a very high dose of vitamin B12. If your symptoms are from taking B12, they should not last long. I would recommend you consult with a local doctor on these to make sure.
Thaking b12 supplement every day cause to lower the thyroid hormone? So u better to take iodine supplement with selenium and magnesium to help with your breath shortness...ps if u have young with no blood pressure took magnesium with b6 so they can't lower u bp and if not just magnesium alone ..
And maybe also ur supplement brand are bad has a bad fillers
Hi Doc. the recent year my B12 has gone up alot. i'm not using any B12 supliments. the suppliments i use is Liposomal vitamine c (1000mg a day) Omega 3 capsules (1-2 a day) melatonin at night (1-2mg)
The 5 bloodtests i did from 2010 to 2020 i was between 507 Pmol/l to 655 Pmol/l and in april 2022 i had 720. And in december 2022 i had 1010, and today i had 1319 Pmol/l
no other than the b12 values deviated outside the norm. My doctor doesn't seem that concerned. we was agreeing on trying to cut out all the supliments i take just in case some of them contains b12. the recent year i have adopted a little more unhealthy diet with more sugars and fast food than i had before. what is your tought behind this example? could it be the diet?
Thank you
It is unlikely that a supplement would contain B12 without listing it.
Hello. And thanks for the videos! Just wondering if while on B 12 injections my levels are high(as should be) but shouldn’t my MMA levels go down? It stays above 1,000. Could MTHFR be a cause? Waiting to get that test hopefully soon. Thanks!
yes MMA should go down but somtimes takes time 1-2 mo. No MTHFR will not affect MMA.
I take regular multivitamin for women 50+. 2016 result was 1000, yesterday, August 2022 test result show 1150. I don't take extra b12 supplement but eating high animal protein like fish, seafood, full fat dairy products and beef, because I exercise a lot and very active and thought the high fat diet is good for my lifestyle. I did not go overboard but should I limit or back to vegetarian diet? Doctor didn't mention anything about it.
Thank you for any advice. I concern about eating diets. The past couple months I experienced pulsing legs, especially when waking up in the morning.
Thank you
It could be from the mtv and in that case it’s not a problem.
My B12 serum level is 944 ng/L
I don’t take any supplements, I have swelling in one arm and had lymph nodes up in my elbow, feel so tired and weak, I’m being fast tracked to the breast clinic for suspected breast cancer? Does B12 being high have anything to do with breast cancer?
Hi Nicola, not typically. Any cancer can theoretically do this depending on which white blood cells are involved.

Hi , yesterday I received my bloodwork back. I have a slight elevation in B12. it read 1064. My doctor didn't seem concerned as the rest of my blood work came back completely fine. She did mention that if I am taking a supplement I should just take it every other day. I have been taking B complex for a few months that has 400mcg of b12. and before that for about three months my other B complex had 250mcg of vitamin B12... I never had low b12 before but just assumed we should all take it... Could the supplement with that amount be the reason for the elevation. I am a hypochondriac so google has not helped.
It's the supplement more than likely.
My b12 is high from taking more then I need just because your level is high does not mean its your liver
Hi Pammy, this is true. Simply consuming b12 supplements regularly is the most common reason for a blood test to show high.
Mine is high, just a bit over 2000. But I have a Myeloproliferative disorder. (Polycythemia Vera) But it’s never been high until after taking ‘chemo’ hydroxyurea & Jakafi.
I know this is in depth, but do you delve into these causes? Mainly out of curiosity for my peace of mind and understanding of my body.
Hi firetech700, There are two other videos on high B12 levels. I think these will help you. th-cam.com/video/71B9OJ81WaE/w-d-xo.html

Dr... I am 28...my platelet count 4.4, PDW 16.2, P _LCR 10.3, vit d 13.8, vit b12 1157........I am worried... Is this count a problem.. Pls reply
I realize this is an old video but I’m hoping you see my question. I just got my B12 labs and they are 1355. I have been taking 17,000mcg biotin daily. Would you suspect this is why?
No but hard to tell unless u avoid it for 2 day before the test
@@swintegrative then I’m confused! Did I misunderstand you mentioning that biotin can interfere with B12 labs?
@@rachelb357 no you did not. It can interfere with a lot of blood tests. It is just hard to quantify how much
Thanks so much for this video. Iv been taking 2 supplements daily which contain 200mg.
How much b12 gets eliminated and how much is being absorbed? How do we test that?
Iv read that too much b12 can cause cancer or cause autism in an unborn child, what is your opinion and do you have any additional resources to share perhaps?
Thank you.
"too much b12 can cause cancer or cause autism". This seems misleading or more likely just false. A blood test tells you how much you are absorbing from your digestive tract.
Hi doctor,
I have a question cz I couldn't find any information on the Internet, and my doctor didn't habe advice for me.
I've been practicing keto diet for a while and just recently did a blood test. Did fast for 15 hours before test. In my test it showed high b12. My question is, since everything else showed ok, is it because of Keto. Thank you
It's not from your body making ketones but could be from increased consumption of animal protein.
@@swintegrative thanks for that, thought so...here is a big steak lover haha
Hi, i took 2500 mcg b12 just .Now i found that daly take should be 2.4 mcg.Should i worry? Why they said that we need one tablet from 1000-2500 mcg per dey when this is too much? Thanks
Some people need a lot more than the rda
Does this mean b12 is a type of protein? Transportation to bring the b12 is poor, due to what? Sorry i m not a clever person. Just asking?
My levels of B12 levels are 337. What does that mean?
That is actually a big low.
Any time i take vitamin b supplements I get very anxious and jittery and can't sleep. It gives me to much energy.
When I take vitamin d I get headaches and get a fullness type sensation in my head.
Can someone please explain to me what the crap is going on? I don't eat amazing or bad.

My b12 is 1150. I don’t take suplements. Is it possible that this is causing me acne?
not likely
I had a Sadi Bypass last year and have all of a sudden had a high level result of 1200 for b12. This is apparently uncommon as low b12 is the common factor after bariatric surgery. I’m meeting with my surgeon today to follow up but I’m quietly panicking because I’ve been feeling unwell with a wide range of symptoms that have been brushed off for some time by medical professionals, which in turn has made my anxiety worse and amplifies my symptoms. I need some reassurance lol p.s. my liver results were perfect, cholesterol was slightly elevated but Dr said it wasn’t a fasting test so disregard that result. Thankyou for sharing this!
pls update how it went.
Hi.Thanks for sharing.I would like to ask you -what symptoms you experienced apart of high B12?
Mine was high back in May ,never checked after.
But since August I have lots different symptoms such as back pain, bowel disorder (diarrhea/constipation),difficult breathing, tiredness. All this make me anxious aswell.Have you sort it out what it caused??Many thanks
1200 is a perfect level for B12...there is no problem with having high levels.....
@@halad2864 same plus dizziness and headaches, got my shots over a month ago. I was nearly passing out and vomiting, exhaustion. Ppl saying that high levels are ok haven't read up on the symptoms, I have 2000 and have being feeling terrible. How are you feeling now?
@@artsylady3187 except nausea, vomiting, headaches, dizziness, exhaustion, brain fog, achy bones, diarrhea dialy. I had my shot over a month ago and all my bloods are fine except b12 at 2000 and they match the symptoms, I wish I felt fine 😥
Hi, I'm vegan and I'm starting to monitor my B12 level. I went to a private laboratory and the b12 level came out very low. I took 1000 units a day. And every 2 months I went to the same laboratory, and the results were low. After a year of taking 1000 units a day, I realized that those in the laboratory were probably wrong and I did b12 tests at 3 different laboratories (same day) and the assumption came true. The question is whether this excess B12 has affected me and what other tests I should do.
Hi Daniel, no I would not worry about it. If you stop taking the B12, you will see the levels coming down each month you test it.
I wouldn't be so sure about that. I took it 8 years ago and got a terrible insomnia and since then I'm not the same and recently I stop eating meat and I'm getting better. So I think this thing can be there for a long time stored in your liver and there are studies that back this up. There's too litter info on high b12, but now people are starting to release information and sharing their experiences on this real problem@@swintegrative
A person taking Coumadin May have higher levels of b12?
No I don't see why that would make B12 level higher.
How long would 600mcg in a shot be detectable in your blood? Would it leave bloodwork elevated for weeks?
Yes typically shots will leave elevated levels for weeks maybe months if there have been many shots.
So if you don't have a liver problem then maybe it's cell membranes not transporting things very well due to genetic stuff. So what can be done about this? My b12 level is 934. Also heard it's a sign you may have some cancer issues. What other blood related tests are worth looking at on B12 ? In an issue in addition to the red blood cell count which for me is normal.
Hello, I have done several blood test in the past where the doctor told me am deficient in B12 ,he told me I should be eating food that contain b12 to boost it, I started eating more eggs and chicken and a lot of fish, recently I did test and I was told my b12 is high and the doctor said I should see heamotologist for more test. Kindly explain further please.
Hi Derick, this sounds odd to me and not sure I can explain. I would have to know more about the situation, like how low it was and how high it is now. A single test being high is not typically concerning but the details do matter. If your doctor made this recommendation, they had a reason. I can't say why.
Mi B12 is
Hi Subba, sorry to hear this there is no way I know of the reduce it but it should gradually get better within a few days or week.
@@swintegrative thank you doctor
so does having 1900 b12 or high b12 with supplement ever cause any problem? cuz i get anemic if i stop b12.
Nope, all good there.
@@swintegrative thanku Doc
I had a blood test in February and my v12 level was 1150 , i am so concerned now. But up until Christmas i was taking b12 supplements 1000 is it ug ? Per day . Could that be the reason ???? My GP didn't seem too concerned.
statistically speaking it is likely from taking b12
@swintegrative thank you so much for replying 😊😊. It's reassuring.
Thankyou so much for this video. I just found out I have a high B12 levels through a doctor phone call today. I don't take injections or supplements and also don't have a high B12 diet. Recently I have had raised liver enzymes levels also. So could that have something to do with why mine is high?
Hi Urban Hawk. Yes this could be a clue but would depend if the liver numbers are always like this and how high they are. It is best to get as many data points as possible before coming to a conclusion.
Your liver numbers can stay normal and u can actually have liver cancer ,cirrhosis or sever liver disease,, My b12 is sky high 1st time in my life ,,was always low actually anemic,, Ive had thyroid cancer n my tumor maker also came back sky high after years of normal,,, Liver cancer?
Same with me what to do
thank you very much for your clear explanations on B12 !
You are welcome!
My b12 level was >1475..i dont have any signs or symp..cbc..lft..kft..blood film all within normal levels..hepatitis negative..abd pelv chest CT normal..thoughts?
Get it re-checked and make sure you don't take any for 3 days or more.
I had a hemogram 5 days ago and my b12 count came off as 1440. I’ve been supplementing with multivitamins every day for more than a year now and have a protein oriented diet (around 150 grams daily) since I lift. I don’t feel bad at all, except the tinnitus I had in my right ear for two months now. It began suddenly and I only hear it when it’s silent, my auidogram’s came out fine so no hearing loss and I’m not dizzy even a bit. Might these two be connected? Should I be worried? Apart from b12 my blood work was completely normal including alt/ast and creatinine.
I would be as grateful as a person could be for anything if you could help me out. I’ve been freaking out like crazy since I got my test results...
Hi Bruh, I would not be too worried but you do want to find out why it is high if you can. You should probably just stop the multivitamin for a few weeks and re-check your B12 levels. More than likely it will come down.
How are things with the tinnitus
Same, nothing's changed. I've lost all hope now though, and got used to living with this thing.@@kwesidarkwa5443
How long does it take for B12 supplements to clear the system? I used to take a B12 1200mcg supplement daily up until 2.5 weeks ago and had blood drawn yesterday and now my blood test results today are showing B12 at 1300 pmol/L.
probably 2-4 more weeks.
Same here used for 1 year 1400mg and today tested 850 pmol/ l. Should we stop also certain food to lower?
My son aged 10 years is having B12 levels 855 pg/ml. This value is consistent from many months. Is it alarming? Does going vegan help reduce B12 levels in blood ?
Seems a little high but really need to check w your doctor. It’s not the b12 itself that is the issue. It is what’s causing it to be high that can be a problem for some.
Subbed and liked, thank you!
Awesome, thank you!
My b12 was 2000. My doctor told me to stop. What do you think?
my B12 is 768 pmol/L and the normal range is 145 - 569pmol/L. Should i be concerned about this?
Many thanks
Hi Mike so this looks like a different reference range than I am use to seeing which is probably because the units are different. So to answer your question. I would only be concerned if you are not taking b12.
Hi Mike, did you find out the cause for your high b12?
Hi, im in the uk, I have blood test regularly, the last few have shown vitamin d deficiency and lft levels were high, unfortunately this was missed, I was feeling ill, bloods re dine my b12 too high, folate too low and lft again 2 high, gp told me to repeat in 3months, if same I will be reffered to liver, could blood transfusion cause this, I have sps so had polyps removed but hemorrhage be 2yrs this June, thank you
Hmmm, not sure what your question is here. Transfusions would not cause these things generally but would look at why u need the transfusion to begin with. Vit d is not directly related to liver function.
My recent b 12 is over 4000.. what should I do? I don’t supplement.. i ha e chronic health issues that are not specific -pains , night sweats, breathlessness, periodic rectal bleeding etc
Mine is like that
This is the best content on the internet on this topic. Thank you for the information. I previously had really low B-12 and low white blood cells so was sent to a hematologist. I am how showing really high B-12 after weekly injections + supplementation. How quickly can I dilute the B-12 out of my body. I started drinking loads of water but hoping to figure out timelines.
Hi Athar, I would expect 3-6 weeks just by not taking it. High B12 is not a problem if it is high from taking it.
i have the same high b12 low whoite blood. Also chronic fatigue syndrome and ehlers danlos. Did you find out the cause of your high b12?

How can we bring down the Vitamin B12 level by diet
Hi Janet, you don't need to bring the level down only find out why it is high.
I have very bad stomach pain. I have B12 injections every 3 months. I was also taking 1000mg of B12 vitamins a day. I don’t know if this is the cause of the tummy pain. I had an ultrasound scan on my stomach, came back clear. I don’t know why I am in pain day & night?
Hi James, I have never seen B12 cause stomach pain.
I’m being referred to a hematologist because my GP thinks I have idiopathic high B12. I’m not taking any supplements or Biotin.
I also apparently have anemia/low blood iron.
What could this mean?
Sounds like a good reason to see hematologist… hard to say but your b12 may not be getting into the cell or u could just have low iron anemia.
I keep asking doctors why my B-12 levels are always high. 1200-1500. It is in some vitamins I take. They all keep telling me it’s not a concern. I am concerned. Should I be?
Not is u are taking B12.
I was taking b complex for more than a year and I just got my blood works showing my vit. B12 is high at 662pmol/L should I need to be concerned about it dr.? I stopped my bcomplex for a month before my blood test. I am low on vitamin D too.
probably need re-test in a month or so.

She complains of sever lower limb pain , distributed pain over her sole . Her whole body MRI shows mild L4-5 bulge and ankylosing spondylosis. what could be the cause of her pain and raised b12??
Hi there, I have a patient who is my uncle having exact same symptoms and same report as that of your mother's. Kindly share some inputs to tell what is this problem. My uncle having vit b 12 of >2000 levels.
Boo B12 does not cause pain like this.
Just got my reports today. My b12 is 1846. I don't take any supplements now. Used to take an year ago. Suffering from Central sensitisation syndrome, dysautonomia, autoimmune. Irony is when i was on supplementation, it was 1200. But now it's 1800. I am on a keto diet, and eat chicken 600g a day. That's all. Very confusing. Idk what my body is telling me. 😢
High protein diet can also raise b12 levels. Please check out my other videos on this topic to get more details
