• Is Too Much B12 Bad (...
"In the fifties, when chemo wasn’t yet widely used, high-dose B12 shots (10,000µg) were given to children with a neuroblastoma tumor, every two days, for 2-3 years. In most patients, the tumor disappeared either entirely or partially."

Exactly! Ones who are pushing a certain narrative appear to try and discredit or minimize the positive impact from vitamins/nutrients; they have no credibility in my book. Because they're subtlety and simultaneously undermining the dire consequences from man-made meds. And a typical omission entails the profound difference between synthetic vitamins (which are usually made by the same pharmaceutical companies as these meds) and organic ones, etc.
Yes, you are correct. Notice how they dont talk about that anymore? Cancer is caused by a parasite. A parasite! Not a vitamin. They lie to us about everything.
The most important thing this guy said in his video was in 4:17 timestamp. Correlation doesn't equal causation! The study he referred to showed people with high levels of B12 but that wasn't supplementing. It wasn't of people that got those high levels through supplementation. There's a big difference there. I think the way he said it was a bit misleading. The levels of those people with cancer was given for one unknown cause. Vitamin B12 is extremely safe even in large doses. There's was a experiment in Japan with astronomical high dosage of B12. And it actually helped the patients. Not a single negative side effect were find.
In this video a doctor talk about how much B12 is "too much"(spoiler: there's no such a thing):

@@Jesse47249 100% correct!
I don’t actually remember what caused me to start taking B12, when my doctor told me I should take iron, a few weeks ago. But, I learned that, being on a high dosage of Metformin, long term, makes a number of people deficient in B12. In addition, the hair loss I’ve been suffering, for about 20+ years, is starting to reverse. I don’t know how much will actually regrow. But, it’s a start. I will get that test done, because I’m pretty sure my GP, nor any other doctor I’ve seen in the past 20 years, knows anything about this.
Thank you for providing a clear and concise message. I really appreciate that you referenced multiple scientific studies. I also appreciate you’re down to earth attitude about the issue. Thank you for not behaving like a sensationalist or a provocateur.
Thank you for the kind words!
@@dustin.k.williams Can too much B12 or Folate or vegetable glycerin cause this?
I just re-started taking a sublingual Supplement that has those three ingredients (and water) ....
I have been taking oral B12 & B-complex supplements that also have intrinsic factor (due to Achlorhydria & yes taking Betaine HCL with pepsin and digestive enzymes for years..)
but this is the fourth time re-starting the sublingual and have tried two brands ... ?
What do you think is "most likely"?
I have tried both with and without all the oral supplements and still... the only difference is the first two times (4 months ago) were horrendous and took weeks to get over each time...
but the last two times have been "less intense" ...but still very bad...
Also the first two times were a B12 ONLY sublingual that only had glycerin and water and NO folate....
I have Achlorhydria and do take Betaine HCL with pepsin & digestive enzymes...
And have siblings that take B-12 shots and everyone on family that has ever been tested has tested low to deficiency level of B-12...
The oral supplements contain many times more B-12 and have intrinsic factor...
Also, would love to know if the "intrinsic factor" in supplements is known to "work" or if it isn't likely to help ?
Wow, super informative! Thanks Dustin. I actually did the blood test and do need the supplements. But loved how you explained that there is such a thing as too much b12.
i really wish you explained what a "high dose" was. there's no mention of levels of daily percentages. only vague terms of "too much" or "a lot"
Thanks for the comment that says no mention of AMOUNTS of B12 he’s talking about so I can write this off as unnecessary to watch. I take 2000mcg orally per my neurologist and seriously doubt he would say it’s too much. I was boarder line low and have MS.
You should never take supplements without first referring to your doctor. I have a problem with not being able to absorb B12 and my level is around 110. I have had symptoms for years and only recently started having injections with medical follow up to check my blood. So far I have had several injections over the past months and my level has not changed. Apparently it can take several months for the B12 to be absorbed in the liver to levels where it is the released into the blood. So it is very important to keep checking your blood.
Honestly the more I go to doctors the more I think they are morons who dont know a damn thing and simply just want to send you home get through their shift and get paid. They do not care about us at all these days. The day i stopped taking doctors advice was the day i started to get better
When I had bad eating habits I took the b12..now I have better eating habits but continued to supplement…I took 5000mcg every day….so Thank you again. I am thankful my DR asked for the test. My b12 is now in the cupboard and will dispose of it when I can
Do you take it after meals or before?
@@MyPlanet123 before meals, I no longer take that dose. I’m on a low carb diet and eat mainly meat. Will get tested again in April.
did you have any symptoms before taking b12 and did they get better when taking it?
@@wakeupp563 No symptoms..had blood test done and levels were really high. Was told to reduce to 1000 mcg. On ketovere diet now, so I take only 500mcg.
Through trial and error, I found I need 25000 mcg to drink wine or eat anything with Sulfites, or I have a deadly reaction being alergic to Sulfites. I learned this from a Doctor years ago, though, I begain taking about 2000, but over the years, I found I needed more. However, I don't take B-12 unless I am consuming something with Sulfites. It works.
Thanks
WOW ... this is wonderful and startling at the same time. Wonderful because there is a remedy for excessive use of B12 but startling because it is not commonly shared. Thanks for this
Please what’s the remedy for excessive usage.. am tingling in my feet non stop been taking B12 in the last 3 months.. supplements with 1500mcg daily in last 3months don’t know

@@serkigiwa7706hey are doing well now?
I was having issues with shortness of breath, jitters, anxiety, all sort of weird stuff. Had a physical... My B12 was WAY elevated at my last physical. Everything else was fine. I was taking a daily B vitamin complex, and my doctor told me to stop it. I have since stopped and I feel much better. My doctor said she sees it all the time. Most people don't need B12.
Glad you’re feeling better!
What form of b12 were you taking?
Omg yes a lot of anxiety which led me to blood work. And everything was good but my b12 was through the roof. I’ve been supplementing daily. Just stopped. Hope the anxiety goes away sooner than later
I don't think that's true. I think a lot of people have low levels of B vitamins. But you have to balance it out with B1.
How long did it take for you B12 to stabilize after stopping the supplements
I have had an unexplained rash on my arm for months. My vitamin B12 level was extremely high . Yes I was taking supplements. I discontinued the supplements and the rash is finally subsiding after months.
Wow I started taking it two weeks ago and I have a rash on both arms at the folds of my inner elbows 🤦♀️. Time to stop!
I don't have a rash but the flushing haven't stopped
for how long were you taking it and how much daily?
What about insomnia, hight doses of vit B12 can cause anxiety, insomnia and depression
@@imeono5955 dont take high doses, if you want to be on the safe side, start with half of the recommended dose
I’m taking B12 1200mcg. Without it my legs go numb. I also have hypothyroid. My b12 levels came out low so my dr told me to supplement with b12
I hope I’m going to be okay after listening to this video 😱
I take 5000 mcg everyday...and i feel great...people over 50 needs that.
hey how are you doing now?
Thank you. It would also have been helpful if you provided some information about the problems that could occur with taking too much vitamin B12.
Great message here ! Be also careful of not taking too much of vitamin B6. At high levels, it can easily become toxic to nerves and cause peripheral neuropathy for instance (tingling or numbness in your feet and less frequently hands). Definitely don't take a supplement unless you're 100% sure you need it.
Yup! I did a video on B6 and mentioned a few of those :)
I have a vitamin B12 overdose. I got tingling in my legs. What can I do? does it have any connection?
@@TeddyB-gk9lc Mine is high as well and my ears are ringing I also have vertigo which comes and goes from time to time, I knew someone years ago her b12 was too high after she drank too much milk and next thing u know her ears were ringing so she had to stop drinking it and eventually it subsided, she had vertigo as well and missed a few weeks of school
@@TeddyB-gk9lc Yes it is linked, avoid b12 or cutback on it and drink lots of fluids so the excess is excreted from the body via urine
@@TeddyB-gk9lc how do you feel now?
I appreciate the research that you state, and I know that they are true, but you should have definitely referenced, and linked them in the description or even shown them throughout the video
Thanks for your feedback. You're right and I meant to get those added into the description. I will definitely be doing that for any videos going forward!

Does it have a affect on my system? Any advice is helpful.
Thank You☺️
Great info & sarcasm! Always keeping it real & interesting!
Very informative video. Thank you. Just had my vit b12 test. No Dr ever told me to get tested after Intold them I took a supplement. My vit b 12 test was at 2000. Needless to say I will no y taking them again. I always monitored my Vit D test never thought to monitor my B12.
Low b12 is extremely dangerous, and it is common to find elevated blood levels after taking supplements, but actual reading will show only testing after 2 months of stopping supplements.
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?
Check if you are taking in too much sugar.
@@roryivey thanks. I will do. Symptoms have gone down a bit. I am being checked by a neurologist and reumatologist. None has mentioned high b12 as a cause, however I have read some people’s testimonies saying b12 was definitely the cause. Anyway, thanks again. Take care
B12 will help you with your symptoms...i would think 🤔
I've been on a b12 5000 supplement for many many months. Lab work came back at 2900!!! I stopped today. I'll let you know if I have any reactions. I was totally surprised and had no idea! I took it for the "energy" it was suppose to give.
@M oh lord! The neurologists I went to said that b12 has none of this side effects, instead they checked amongst many things my b6 levels, which odd enough came back above the healthy levels. This might be the reason why I have those symptoms. Also the huge level of stress I am going under might be the issue. I really hope you feel better soon.
I took it for years while dealing with Chronic Fatigue and found out I had way too much in my blood when I was tested.They told me too stop taking it at the Mayo. A couple weeks ago I was given a bottle free multivitamins for men over 50 while buying some of my usual supplements.I forgot to look at the label and started taking them thinking this will probably be good for me.I have been experiencing numbness,stiffness and dangerously low energy,nausea.Are these symptoms sometimes experienced with too high of B6-12?
I too have been experiencing numbness in my extremities along with my hands and feet. Although my doctor never told me this could be the reason for my numbness, she did tell me to stop taking the B12 because my levels were too high. I stopped taking the B12 and after two months, I am still experiencing the numbness and getting quite concerned as I am thinking this could possibly be nerve damage...:(
I wonder if he actually did more research than just the one study he talks about, but DOESN'T SITE so others could check his references for accuracy, and for research methods used in the study (e.g. controls for variables, number in cohort study, b12 serum vs. homocysteine levels, etc.) Dustin may want to learn these before making further statements regarding B12
While you are pointing to a good point on balance and identification of deficiency, you are need to point to the B12 that was used. Was it the Cyanocobalamin: This is a synthetic form of B12 often used in supplements and fortified foods.
Please link your research reviewed.
B12, B9 and cofactors B6 and the other Bs are necessary. Please review the data if you
Hello! Mr. Williams, that you! for this GREAT! information. But how much is too much? Everyday for a year or more. And if you don't have a good diet of eating, is it okay to supplement for just a little while.
Too much depends on the individual. Some people need extra supplementation.
@@dustin.k.williams THANK YOU! DUSTIN, I'm taking liquid B12 of 5000mcg per serving, only once a day. So, is that safe enough and how long should I take it? I'm 65, 5'11 and 280lbs.
Ive been spraying many times sublingual last 2 weeks and yesterday I had a really bad reaction. Pulse changes, arritmia, wheezing, vertigo, I thought I was done. Very thirsty-GM drank tons of water. Lost 5 pounds in 48 hours (diarrhea and nausea).
You don’t actually list any negative side effects of taking B12, or optimum/ deficient values.
I have b12 Defenicy 2 years ago i took b12 1500mcg per day for 8 months and i was feeling so good but now im b12 defiency again because i dont get b12 daily from diet is it safe to take b12 5000mcg per day or one in 2 days or 3 days?
I’m curious as well. For some reason I just bought 5000mcg & took it this morning. I noticed I had serious dizziness this morning when walking. Almost like I was drunk. But I also noticed I felt so much more energy and felt very natural today more than ever other than the dizziness. I’m going to go check at my doctor and see what my bloodwork says.
Very informative, thank you for posting this!
Hi , i did bloodtest and i have a high B12-Kolabamin around 100 more .. i train regulary and eat a LOT of meat, eggs, cheeses and so . I dont know if its dangerous to have s high B12 ?
B12 serum test is completely unreliable mine were off the charts and I wasn't taking enough of it to make it at that level serum B12 test not reliable don't do it
This week I started supplementing with iron that contained 1,250% RDA Cyanocobalamin. I started feeling unwell and digestive issues - lots of stinky gas and excessive bowel movements and heart palpitations. I suspect I’m having toxicity response. I also suspect that I have a methylation problem or some other issue - either genetic or pernicious anemia (autoimmune). I’ve been mildly anemic and low ALP my whole life and anemia unresponsive to supplementation. I have a whole slough of mild to moderate health issues that may be explained by pernicious anemia or methylation issue (MTFHR issue perhaps).
I’m wondering what I can do to support my system to detox from cyanocobalamin. I haven’t found information for that.
this is great brother! really enjoyed watching your video, cant wait to see more from you! keep them coming :) thanks for sharing
I was taking 5000 mcg was only supposed to be taking 500 and now my red blood cells are enlarged and I have high b12 how long will it take for my b12 levels to go down since I’ve stopped taking them
Hi, How are feeling now? I had high b12 after a test 3 weeks ago, so I completely stopped the supplement. Uncomfortable sypmtoms as well. I feel a bit better now but not normal. I hear it can take several weeks/ months for excess b12 to clear.
I heard the same thing. I have only been off of my B12 now for two months and hope symptoms go away soon!@@robertz7753
@@robertz77532 year 😅 atleast
The research studies mentioned in this video had dosages in the astronomical range. No normal human being swallows that amount. Peripheral neuropathy actually requires up to 3,000 mcg of B12.
Also, there are various forms of B12 and B6. Methylcobalamin B12 and Pyridoxal 5-Phospate B6 are the safe forms to consume in large reasonable dosages.
Cool video! I took 1000 micrograms after two antibiotic treatments from having lyme disease, I got super tired from just being awake. My doctor said I could try B12, due to my stomach flora might have been compromises. It is better for sure now. Took one tablet a day for 3 weeks. I'm not on it now. I did not test my levels though.
I have a serious question for you. My Doctor told me I have to much vitamin B12 in my body. But he didn't tell me how to get rid of B12 can you help me deplete my body of B12 I have a over active nervous system. And it's driving me crazy.
I would like to know as well! My doctor never told me either. She just told me to stop taking my supplments.
I have mthfr gene defect. Blood test showed very low b12. Took 3500mcg for a while, now 2500mcg. Dr. hasnt followed up on blood tests in 17 months. Should i get it tested myself?
wow, doc told me to take vitamin b12 methylcobalamin 5000 mcg in 2015 and still taking it because not 1 doctor since then has told me to take less of a dosage. Why? I fear they're not being truthful with me. I'd appreciate your advice. Thank You.
Every day? For most people prescribed this much B12, that is, at most, a weekly dose. (That's a once per week dose for vegans over 65, as far as I know!)
This is good to know because they will tell you anything to sell!
Is b12 messing the liver?
I took b12 for a few weeks and now my liver is acting up. Also i am getting a severe case of depression.
Are you taking the methyl form?
Me too, I have insomnia, depression, anxiety, my doctor told me stop taken B12
Anyone experienced tinnitus from taking a b12 supplement and being above the desired range? If yes, how long after you stopped taking the b12 supplement did the tinnitus go away? Thanks
This is very informative. I had my B12 tested and it was on the highest side of the normal range. I have been supplementing most days for a long time. Was was getting shots a few years ago. My doctor said to stop taking the supplements. I have taken many different brands. Most recently Nature Made.
gummy 1000 mcg . Have stopped. How long does it take for blood levels to drop?
The amount of time varies. I personally would wait at least 90 days before testing again.
I have very high too 1006 , the border 894
I'm worry , how can I low the b12? Please hlep
Could you post links for the research you're presenting please?
Great video, thanks for the bloodwork recommends.
You’re welcome!
I have had breast cancer now or two years. My last bloodwork showed that my levels were too high so my doctor told me to stop taking the supplements.
I read somewhere that too much B12 can cause numbness and tingling in the extremeties, which is what lead me to receive an MRI to make sure there was no metastasis to the spine. The MRI showed none, but after two months of being off of the B12 supplements, I am still experiencing the numbness in extremeties.
Have you heard of this before? This is leading me to believe perhaps the overdose could have created some kind of neuropathy condition/nerve damage? Thanks!
Do you supplement with B6, if so perhaps this could be possible cause
Same thing same shit
@@zaneex9562 it took a while, but no longer have the numbness and tingling in my legs.
I didn’t hear from you, what is the “too much” level? I am taking 1000mcg supplement. Is that too much? It was prescribed for me.
Ive been taking vit b12, ive been feeling unwell and only getting worse so doc had me do blood test, i had very high levels of b12, so im laying off the supplements
Hopefully that will help you out!
I have been told I needed to do Hydroxycobalamine injections. I tried doing 1 ml twice a week in 2020, but started having headaches and was convinced the injections were the culprit. Now I am not so sure. It could be something else causing the headaches.
Now in 2023 I decided to give it another try. This time 1 mL twice a month. I started on January 23. Yesterday I got the second shot, and I feel like I had a reaction again, and this time was more serious. I felt confused about what day is tomorrow and what appointments I have. I thought that today was Friday, but today is Thursday.
Also I did not feel like driving in the evening after 4:30 PM. I felt helpless in a way & felt as if I was getting sick like from CoVID when I start running a fever with feeling of needles all over my body.
What was that? Can you explain please?
Thank You for your video!
I can lay down all my day full of anxiety and depression and mood swing should u take mecobalamin
Great video, I've just started taking B12 1000ug methalamine?? Type, I am just presuming I'm low as I suffer with fatigue a lot, 60 no health issues and fit. Maybe this is too much ??
My son takes 1,000 micrograms of B12 a day prescribed by his doctor because of a B12 deficiency.
Hello! I have had bad b12 deficiency symptoms for two years and then one day I took it and they were relieved. For two months I felt better finally then the shortness of breath, Chest pain, lethargy, nerve pain and slight disorientation returned even though I'm still taking b12 liquid. Do you know why this would occur? I'm getting labs done but I think he only checked blood levels of b12.
Yes! I just had a gastric bleed of the stomach. Hospitals found I had 7 bleeding ulcers. Had proceeded endoscopy . They gave me a medication through it to stop bleed. Ulcers from aspirin culprit. Eats holes in stomach. Bled a maroon color from stomach. Had your symptoms and more. See your Dr soon. Wish I had.
Blood work showed I was low tried getting through diet didn't seem to work..
This wk started injections..
Mon,weds,fri..first 2 were fine and 3rd till tonight I'm getting itchy all over and skin is hot.. can antihistamines help? Could I of over dosed?
As a vegan, how much should I take? 1000 mcg daily? More? Less? Thanks. :)
I started taking b12 after a doctor said it could help my energy levels. My b12 was never tested though. I’m going to have it tested before taking any more. Thank you for the info!
and how did it go? were you deficient?
Hi, I have had anaemia for 4 years but my B12 is above high level on my blood tests. I do not take supplements and haven't eaten red meat in over 30 years. My dr cannot understand. Lots of info about b12 deficiency but nothing about too much b12. Any suggedtions please?
test iron and folic acid levels, also how does your vitamin d levels look?
I have been taking too high levels of liquid B complex unknowingly for many years and now have elevated B12 levels as well as creatinine, Alkaline Phosphatase and ALT levels. Can this be due to the high B12 levels and can it be reversed by reducing or eliminating B vitamins? I have an organic vegan diet and concerned about these high liver levels. I am a runner and benefit from the B vitamins though deeply concerned about cancer and early mortality due to these years of high levels of B vitamins! Thank you!! I am grateful for your videos!!!
Thank you for the kind words! Elevated liver enzymes can be caused by multiple different reasons, so it would be really hard to say that's due to excess B vitamins consumption. Most B complex supplements do have too much of the B vitamins (in my opinion) for long term consumption.
Your videos somehow always relate to me. I dont eat meat so I take one b12 everyday
I do test low on Vitamin B12 so I was given 1000mcg tablets. Then, my B12 came back high. Nothing was said to me that this could cause any problems whatsoever. However, I began only taking a tablet every other day.
I didn't feel it was helping me either way.
Then I discovered through some study because I have a condition called CMT1A and my body doesn't rebuild Myelin I probably had a different need for something with L-5-MTHF and I
should probably take something else that I could more readily absorb so now I take Methyl Folate +. This has 500mcg B12 instead of 1000mcg I was prescribed.
I seem to be having more energy on the new different supplement after a month or more.
Hi thank you for your video! I'm nervous because I first did my own B12 injection into the butt area, following the correct method, and I now have a sore lump not visible, but intermuscular. Its been a month...Then I went to have a doctor do the next one on the other side, and after a week, I now have another lump on the other side underneath the skin😢
Has anyone had something similar?
I'm not taking any b-12 supplements and I have high b-12 (962 pg/ml). I'm on the keto diet.
Wow! My B12 is 1200 and I am having muscle weakness and tingling in my legs and feet. I have been supplementing with a B Complex every day. I thought it would help me stay mentally sharp. I will stop my supplements.
HI, have you gotten better?
Could be a Vitamin D deficiency - has the same symptoms of tingling in hands and feet plus weakness
I have been taking the mega food blood builder for almost a year now, because my doctor said I’m anemic I need to take iron… But I just had a follow up test and I’m still deficient in iron, but now I have too much B12…
B vitamins are water sociable drinking water would flush the vitamins out. My neurologist told me to take B12 B6 and B9. I was deficient
I use 1 every other day because of numbness in my feet.
One pill 12000 (twelve
Thousand) I feel aweosme !
I've been suffering from anxiety for about 6 months and I have fought it all naturally but I just discovered that it was Vit. B that are creating my anxiety, anything that contains B Vit. will give me anxiety after much testing and trying different brands and tipes it seams that give me axiety....could you give me un idea why?
Same here
It may not be anxiety. My vitamin B12 levels were high because I was taking too much and I was having shortness of breath and a “nervous” feeling. However and antianxiety did not help. I did not realize my blood levels were that high until this week. Stopped the B12 immediately
That is definitely a thought, something to look into...
@@redbarron1010 I'm having the same! How is it going now? I got chronic insomnia from it, which escalated into panic attacks and later into psychosis with hallucinations etc.
CSE much better since I stopped taking the supplement. I have occasional shortness of breath but that’s it. Be careful of any supplement. Some of the ginseng type stuff will really mess you up.
WoW I'm T.B.I and B12 helps me Big time. I take 20,000mg of B12 and I feel Great plus my workouts got better.
Glad to hear it’s working for you. Every persons needs can be different.
I think my b12 supplements are causing my current bout of insomnia. One tablet contains 100ug, and the DRI is 2.4ug. Meaning that I'm having 25x the recommended daily intake. Last week I slept an average of 1-2 hours a night, only one good night of sleep. Weirdly though I don't crash during the day, I just feel wired all the time, no urge to nap.
Interesting as I'm not familiar with any research on that dosage impacting sleep. Are you still taking the b12 currently?
@@dustin.k.williams I’m going to stop taking them from today. I told my GP and she said she hasn’t heard of these side effects either. To be honest maybe I’m using motivated reasoning to think of something immediately obvious that’s causing it as I want to find the problem and for it to be over 😫
@@RapidBlindfolds Understandable. I've done a video on sleep. Maybe you can check it out, if you haven't already, and it may give you a few new things to look into. Hope this helps! ua-cam.com/video/ud0_JEx4jHw/v-deo.html
@@RapidBlindfolds thanks for that. I'm lying here trying to figure out why I can't sleep and why my energy during its like CBF. I felt that B12 might have something to do with lack of energy. I slept well last night but had CBF today. I recently had my blood done and by B12 was good, 500. So I am going to stop the B12 as of tomorrow as well. Wish me luck.
It was coffee. I had one too late in the day. Ugh!
Doctor has me on b12 plus shot every month should I worry since doctor makes me take
I would not disagree with what your doctor recommends. They should know your specific needs. But, I would make sure they’re testing your B12 levels in your blood
I take Vitamin B12 because I started metformin and that depletes your B12
Thank you for explaining this. I was diagnosed with a B12 deficiency in 1999, so for the last 23 years I’ve been injected 6 weekly with B12. I’ve now been told my B12 levels are elevated and far too high. This has caused me much concern and health wise I’ve suffered as I didn’t realise it’s just as dangerous for levels to be too high as been too low. I feel very let down as I was obviously mis diagnosed and have received injections for 23 years that I didn’t need. Thank you for informing people about this as it’s not really a very well known condition. I was told I had pernicious anaemia and would require life long injections as however much B12 I had in my diet my body due to my intrinsic factor would not absorb it!!! Still in disbelief how let down I’ve been by my GP at the initial diagnosis. 😢
Wow...i have breast cancer and I am on a whole foods plant-based diet so I was taking way too much B12 unbeknownst to me! My blood work showed it was off the charts and my doctor told me to stop taking it immediately! I was having numbness and tingling of the extremities so I got an MRI which turned out to be ok. Then i decided to google too much b12 symptoms and it said it can cause numbness and tingling and even pain to the extremities, which I was experiencing! It's been one week since I have ceased taking it. Let's see what happens. Good luck to you.
Your levels aren't too high your body is not absorbing at a cellular level the B12 and that's why it looks like you have high B12 serum levels
when you get b12 injected - you can't check your B12 levels because of the injections. you should check the celluar levels. the most study cases shows that overtaking B12 is not easy to do. but why overdo, I agree - the right dose is the right dose.
Wow thanks for this video so I do two B12 injections twice a month I did my bloodwork yesterday and I have 2000 B 12 so I had gastric bypass seven years ago so my body does not get B12 through food so now I have too much and I’ve been feeling very lethargic now I have too much B12 in my body how do I get rid of it
Chill your fine
Wow.this video was a big help But my question us this.Can a high b12 level make you overweight and make it hard to loose weight? Last 3 times had blood work done my B12 levels were 2600,2400,And 2300..So I can't figure out what's going on.
No, high B12 shouldn’t impact your ability to lose fat.
I rotate supplements to once a week and still feel it’s too much as I broke out. I was trying to not overdo it in case they help but in case they hurt won’t be bad and I still got screwed.
I started taking a B complex about 3 weeks ago and I seem to be packing fat on my tummy and thighs. Could this be the reason? My diet has not changed whatsoever.
Nope. Excess b12 won’t cause you to retain fat.
i took up and up target brand vitamin b12 2500, every day for a week and i started having face flushing.
2.4 mcg recommended daily for adults. stop taking anything if new systoms appear and if not done by blood test.
Thank you! Very informative!
More than welcome!
PEOPLE HE IS WRITE
My story
Few years ago I was deficient my old MD put me on 150 mcg
I was doing fine
New MD put me on 1000mcg
The next blood test , he called me and said stop taking it
My level 14000 mcg and normal level is 700 mcg I am 20x over
I am scared please help
All my tests results was ok
I've been taking b12 for a few years, and last week I got lab work and my b12 is 1500. I have stopped taking it.
Love to see people taking charge and getting blood work to learn on their own what they need!
Be careful there can be side effects for most people
@@Markboyy1984 i heard too much bad for kidneys or liver?
@@sharonallison8991 yes I heard it can be toxic for the liver
Did your level go down?
Once a day. 2,500 mcg
I've always suffered from dizziness after standing, even from when I was a teenager. I must have been low on this for ever.
The type of B12 makes a huge difference. Hydroxocobalamin grabs heavy metals and takes them out of the body.
If taking methylcobalamin, people often find they need to balance this with adenosylcobalamin. Unfortunately, methylcobalamin is cheap and stable, adenosylcobalamin expensive and unstable...you see where this is going?
Nutrition geeks sells a years supply of vitamin b12 with both those forms of b12 you mentioned. £8.99 for the years supply and is good quality
I had a very high B12 level on a blood test but they never said to stop taking it before the test and I took over 1000ug sublingual for years.
Please im trying to get b12 but i don't know how and when to get it please tell me how
My Vitamin B12 levels are in the 300-400 pmol/L range. I took 2 injections of methylcobalamin 1 week apart. After the second dose, I experienced a headache, terrible anxiety and insomnia lasting for days. 9 days later I've just started to sleep a little better (4 hrs last night!) and the anxiety has started to calm a little but my B12 serum level is currently at 1132 pmol/L (normal range in Canada is considered at 138-652).
Any idea how long this will take to get back to a normal level and any tips on how I can actually LOWER my B12 level 😞
Thanks all.
(My 1132 pmol/L B12 level blood test was taken 8 days after the 2nd shot... I'm very scared that I'm going to have elevated B12 for a long time..)
There is no need to worry. B vitamins are water soluble. Just drink plenty of water and the body will excrete the excess b vitamins in the urine.
@@jimdoukis7496 Did you get B12 levels tested again? Wondering if you learnt how long before B12 serum levels returned to normal range.
The following from the MSD Manual (& not on B12 injections or oral supplements, nor B12 on serum levels).
"Unlike most other vitamins, B12 is stored in substantial amounts, mainly in the liver, until it is needed by the body. If a person stops consuming the vitamin, the body's stores of this vitamin usually take about 3 to 5 years to exhaust."
I've just been tested and have an excess of B12, and don't use supplements but I have recently been treated for breast cancer! I don't understand why I have got an excess as my diet is reasonable but it is a concern.
I am diabetes type II and start having peripheral neuropathy about two weeks ago. How much B12 would you recommend?
Are you on metformin? It blocks the absorption of b12. You might have to take a sublingual but they’re high amounts. My forehead has broken out so I don’t know what it is.
@@mem1701movies I was on metformin for a while. I watched many videos from Dr. Eric Berg, Dr. Ken Berry and Dr. Jason Fung. About a month ago, I started Intermittent Fasting and Keto diet. Now my A1C down to 5.5 and stopped Metformin. However, the numbness and tingling still on my both feet. I start taking Benfotiamine, B-12, B-complex, alpha lipoic acid..along with my other vitamins. I take about 7500mcg of B-12. Maybe I just need to wait for the nerves to regrow?
Think I'll drop a quick dissolve 10000 tablet into a 32 oz drink and just sip it slowly during the day
If I have super high B12 serum levels how do I determine if it’s because of malabsorption or something else and how does one lower their B12 without eliminating completely animal food
In the majority of cases it’s uncommon to have super high serum b12 just from food.
Hello Dustin....I drink a cup of vitamin infused coffee daily. It has huge amounts of B6 and super huge amounts of B12. Also has MCT oil, cinnamon and tumeric. B6 = 5mg and B12 = 240 mcg along with large amount of Thiamin and D3. My thought was that since B12 is soluable it could not be too much. After watching your video I am not so sure of that!
With your B12 numbers at 240 mcg it's not a high enough number I would worry about and 5mg of B6 is a perfect amount to supplement with!
@@dustin.k.williams THANKS!
I am eating a carnivore diet and my B12 is at 800. What do I do? I do not take any supplements.
You get a lot b12 from meat and dairy sources. Some tests will show as high as 950 still being in the normal range.
Do some research on optimal range and you will find that 800 is fine, mine is 165 which is real bad and I lack energy big time. Will be getting shots to build it up. Around the world many countries 500 to 1300 is now their standard range
I took a b12 capsule daily for a month, and I got my periods again just after 2 weeks of the end of the period.
Can b12 be the reason for period irregularities in women?
Maybe not, these are water soluble vitamins
Great info!
I’m just taking it every other day so it won’t build too much in my system.
What about taking 1500mcg daily.is that safe?27 yrs old.
A while back I was supplementing with b12 liquid but stopped. But now I'm taking nutritional yeast by Braggs specifically for the benefit of B1 and B6 but noticed it has b12 of 563%...that sounds like a lot so I'm skeptical how much should I even be consuming
563% is at least less B12 than what you get from most basic B12 supplements. There are several factors that play into the absorption and utilization of B12, but it's a cheap and easy blood test to get during a yearly check up just to know where you're at on average.
@@dustin.k.williams very interesting...Since I also eat meat especially salmon and consuming the nutritional yeast. I've wondered if all of that is too much so yeah I'll look into that blood test. Thanks for answering btw!
The standard range for b12 is 2.4 mcg and my multivitamins is 6mcg which is almost tripe the standard and i assume its causing my b12 to be high
I'm checking the dosage info on my super B complex bottle. It says 100mcg. Is One Hundred mcg enough for a 47 year old daily? I would appreciate your advice and response. Thank you
Impossible to answer without knowing how much you get from food, blood work, etc. There’s ALWAYS more to it than just supplementation.
My B12 tested quite low a few years after a R hemicolectomy + a resection of the terminal ileum (secondary to an intussusception). I ate well of meat, fish, eggs & dairy in the years before & after this, but I guess I was just using up my stores. Thankfully I was able to build it up with oral supplements (50mcg a day). So it seems I have just enough distal ileum to absorb it orally, but I do need the supplements. At least I think I still do.... lol. It's been several years since I last had a B12 test. I don't take a complex, just B12 in cyanocobalamin form, as the methyl form is only available where I live as part of a MEGA B complex dose, which contains quantities of the other B vitamins that are between 2000% & 6000% of the RDI. No thanks.
What I'm not sure about though is if serum results from oral supplementation can be very high like in someone who has been supplementing parenterally. I know of several people who become highly symptomatic of low B12 when they're late for their injections, even though their levels are well above normal by blood test.
