Vitamin B12 - How Often & The Dangers Of Taking Too Much
VloĆŸit
- Äas pĆidĂĄn 22. 08. 2024
- Dr. Klaper tells us about vitamin b12 benefits and the dangers of vitamin b12 deficiency. Due to modern sanitation, there is very little b12 vitamin in a plant based diet so we must take vitamin b12 vegan supplements. Both Methylcobalamin and Cyanocobalamin are about the same in terms of vitamin b12 absorption. Dr. Klaper warns that taking too much vitamin b12 has been shown to potentially increase the risk of certain cancers.
Question: Does our body store Vitamin B12? Do we need to take it daily?

this is CRAZY !!
why you are NOT TALKING about to do - BLOOD TEST !!??
like
seriously - W H Y !!!
Is the recommendation the same for people over 65 years of age? Thank you, Dr. Klaper.
I'm just one of many - which CANNOT absorb Vit B12
You HAVE TO do test - to find that out..
and with that kind of 'advice' - I would be - dead !
I need injections
the reason WHY you may not absorb are MANY..
- pernicious anemia !!
- many - autoimmune diseases /my case/
and you don't know about your ability to absorb it - UNLESS YOU test it
that's it
@@lauried4439 do blood test !
Vitamine D Supplement for winter country without much sun exposure and vegan?
often indoor and often cloudy
I thought a lot of doctors in CZcams were saying that Methylcobalamin is the best form, and to NEVER ever take Cyanocobalamin as it is not only hard to absorb but it also contains Cyanide which is really bad.
Correct cyanocobalamin is man made banned in Europe Australasia . If you high b12 and high homocysteine, that is an indication that you are b12 deficient
Exactly !
It can cause more damage having that fo if B12 if you have the MTHFR gene 𧏠mutation
Methyl B12 5mg dose twice a week for deficiency. Especially if you have anemia , low iron and take pharmaceutical medication, plus drink đșalcohol.
So it really depends on how much youâre abusing your body doesnât it!
And lots of humans are on full processed foods , Alcohol and medication so you should take it every day.
2:12 High homocysteine is not necessarily a sign of B12 deficiency. High homocysteine might be caused by fatty liver or folate deficiency, as well as choline deficiency (these things work together with betaine in the metabolism of fats).
( I personally had fatty liver disease, but it wasn't because any kind of deficiency; I just consumed too much oil and fats, in general, which my liver wasn't able to process and I ended up with fat being built up in the liver.)
If you're trying to know if you're B12 deficient, take a B12 test instead of checking your homocysteine, because high homocysteine levels are caused by many things.
Take B12 only if you're B12 deficient or insufficient and if you find that your B12 levels are low, not because of your high homocysteine. Sometimes B12 supplementation doesn't treat high homocysteine levels, because, as I've mentioned above, it is not the only cause of high homocysteine.
It could also be folate or vitamin B6 deficiency.
But recently it was discovered that zinc and vitamin B1 levels also have a connection with homocysteine.
But in the vast majority of cases if homocysteine is high there is a problem with B12... not in all cases but in most cases yes.
Could also be COMT gene mutation.
I've been taking a therapeutic dosage for neuropathy pain of 5mg/day since August. Pain relief has been dramatic - not total, but dramatic since starting these neurotropic B-Vitamines. I am NOT taking a commercial product like MetaNX - bei Alfasigma, NeuRx-TF - Bakodx, âThe Protocolâ, NerveReverse or Nuphoria, but rather a combination of B1, B6 (P5P), B7, B9 and B12 as well as R-LA. ALC, NAC, Mg and Omega 3. The last 5 I've been taking since around 2016 and I was first diagnosed with ideopathic peripheral polyneuropathy in 1999 and then again twice in 2012. In the studies I've read of neurotropic B Vitamins, with or without other substances or individually, the tested dosage was between 1.5mg/day and 100mg/day for up to 24 months. NONE mentioned any serious side effects, the only minor ones have been stomach queasiness, which I occassionally get. But R-LA, ACL, NAC and Omega 3 can also cause that.
Still waiting to hear the result findings on EPA /DHA supplements, is it still up in the air as to whether itâs safe to take it or not ?
Hi Jewels, yes I will do an update on this soon!
Great information, thank you!
What would you consider to be too high a level of B12? Mine was recently 1800 and I was taking 2000 mcg 3-4 times a week in a product called CerefolinNAC which a doctor recommended to prevent cognitive decline ( Iâm 74). I freaked out when I read that high B12 is associated with myeloproliferative disorders and solid tumors. Thank you.

Is marmite good b12 source?
You and Dr. Gregor have different suggestions on how much b12 to take. Dr. Gregor says 1,000 mcg a day for vegans over 65. He also, suggests using cyanocobalamin version of b12. As a layperson who respects both your opinions, help!

@@missbs1 Dr. Burg isnât a medical doctor however. So Iâd suggest to follow advice from experts in the field.
Did you get an answer?
Not yet.
@@Stargazer9900Berg used to teach nutrition at a college. He knows FAR MORE about nutrition than the vast majority of doctors who know next to nothing about it. My nephew is a doctor and heâs very disappointed that the taught them nothing about nutrition other than going over four basic food groups in med school. Youâre dreaming if you imagine that just because someone earns and MD degree that this alone makes them nutritional experts.
We love you, Dr. Klaper! Do you ever come speak at the medical schools in Omaha, NE?
Hi Miranda, once we are all able to travel again I will resume my visits to medical schools. You can email me at www.doctorklaper.com/contact if you have a specific school that is interested. Thank you!
What if you have low stomach acid, lack intrinsic factor or donât have the proper gut bacteria? Any of these can make it impossible to absorb B12. You didnât mention it might be best to take a sublingual form of the vitamin, preferably Methylcobalamin so your body wonât have to convert it to Methylcobalamin like it must do with the synthetic Cynaocobalamin.
Remember though that back then when people were drinking water out of steams everyone had a belly full of worms! Or worse. Dysentery, Cholera, Giardia and many other dreadful diseases were very common back then. Abraham Lincolnâs first love, the âLove of His Lifeâ, died that way, from drinking tainted water. No antibiotics back then⊠General Robert E. Lee said that the main reason the South lost the war was because most of his army had WORMS! And the worms robbed his men of their vitality.
good informations
is not - you NEED blood test !
fist thing
Dr Klaper - your thoughts on the book âcould it be B12â? It recommends serum b12 injections and getting your b12 around 600-800 due to research.
Nobody had any thoughts on it in two years?? I hope someone comes along and answers some day.
Could high serum test levels be a result of B12 analogues and not an actual accurate level? Thank you.
Great help thanks dr k .when you have a blood test is there a number that you should try to be at with your b12 so you know whether your too high or too low just roughly ta
Hi doctor I am new there. I was diagnosed with reactive hypoglikemia. It is safe for me to do some juicing detox or eating only fruit for like 2 weeks? I want do some detox

Quick question: Would you recommend combining methyl folate with b12 2x per week? I can't seem to find enough information about this online.
Unless you have bad kidneys it is hard to impossible to get to much B vitamin... But if you manage to get overdose it is horrible and can take months to recover.
Is 500-1000 mg ok for my kids as well? Ages 9,12 &13. Or should I lower their doses?
I have to much B12. I drink alot of milk and take supplements. I try to take them every other day now. I dont eat much meat and rarely eggs
Is it okay to take a liquid form of b12 cyanocobalamin once a week 2000 mcg? Or it has to be 1000 mcg twice a week?
TINGLING, NUMBNESS, BURNING AND SLIGHT PAIN PROBABLY DUE TO âoverdoseâ 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 âoverdoseâ of b12. I have been feeling this for a month. Anyone out there with the same issue?
It's possible. I actually got chronic insomnia which escalated into psychosis after not sleeping for 4 nights in a row. This all happened after a B12 shot. I found some abstracts on pubmed speaking about hypervitaminosis from B12. So it might not be as harmless as some think. Did you notice increased agitation, anxiety and insomnia too?
Iâm feeling this way too. I was taking 5mg of Vit B12 w/o checking my levels.. last October, been having numbness, tingling sensation, feeling like I have tight socks and burning on my feet. I got checked and my vit b12 was around 3000. I stopped taking it for a month and somehow my symptoms are still there but mild compared before. Iâve seen a neurologist and more labs were drawn. I did the nerve conduction study and itâs negative and vit b12 lowered to 1000+. Itâs been 2 months and I still have the symptoms but itâs mild. Iâm frustrated coz I want to be back to normal. How long it took for you to feeling normal again?
@@marucruz3141 get checked you nerve small fibres which is a different test to the electricity conduction test. All neurologists have told me B12 has nothing to do, however my b6 levels were high. Check those, perhaps the supplement also had b6. I ended up in psychiatrist because of anxiety and depression and they gave me duloxetine, it helped a lot, at some point I was nearly back to normal, but lately I have been feeling the burning/tingling symptoms again. The conclusion to this moment of two neurologists is that it is a âmindâ related issue. Thatâs my story, if you want any more information I am available to answer. I really hope you feel better.
@@sergioduque9050 yes The B6 level was normal. Iâm for another set of blood works then I have to ff up w my Neurologist again. She wasnât worried about my b12 anymore but she is trying to rule out celiac dse coz my copper is low and B12 is still high. She also requested for my zinc level. Idk what to do, I feel itâs not doing away. The numbness is less but the pins and needles are now back again.
@sergio duque , how did you get your b6 levels checked
What if my b12 is super low and i have pernicious anemia? I was told 1000mcg (methyl) a day for a month. Please advise!
Hi Atomic Poppy, for individual cases such as yours that require a deeper understanding of the issue, please consider booking a consultation at plantbasedtelehealth.com You can work directly with me or one of the other plant-based doctors.
A small dose of B 12 me and my daughter take it as a supplement everyday and it gives me a light feeling.
I'm confused. Different Doctors saying Different things. I heard Vitamin b12 is water soluble and it's hard to over dose, cause the body takes in what you need and you pee out the extra. Also was told it's not stored in the body, so you need to take it everyday.
I was a stupid stupid man.. i took 2 2500 MCG tablets of B12 once.... been avoiding it since.. i'm terrified i'm gonna lose my eyesight or worse..
Can a WFPB diet cause a low white blood cell count?
So I have noted that my white blood cell count is lower since I adopted a wfpb diet and dr greger states that. It had to do with not needing a whole reactive white cell count. Makes sense to meâŠâŠI feel good though. My non wfpb docs worry all the time
I take Dr. fuhrman's womens multivitamin every day and I know there is B12 in that. Do I need any more? Also, I'm not too sure about the omegas. I have heard so many different things. Any resources for a solid list of what exactly is needed and how often and if the multivitamin covers it?
All I know is, these vitamin C gummies with B6 and B12 taste so good I can never stop until the bottle is gone.
Anyone experience tinnitus from taking too much B12 supplement?
No but Iâve experienced it due to a deficiency in B12.
Yes I have tinnitus and have taken b12 for years. For the last 5 years I've been having terrible migraines and nerve pain in my face. Had scans which showed up nothing wrong. Then I had a blood test and my b12 was so high it was almost off the scale. Doc said to stop taking it which I have and I haven't had a migraine or nerve pain since. I'm hoping the tinnitus will dissappear also or at the least calm down.
@@janetmarsden8199I wonder if itâs the high b12 or the lowering of other b vitamins like b1, b6, etc. Because Iâve heard taking just one b vitamin will out-balance the others.
My WFPB doctor suggested that I take B12 Cyanocobalamin 100 mcg a month! Do you think that is sufficient?
Look Sir, everybody wants to know how much of VB12 they should consume. Many of us have the 5000mcg I take it once a week but you said 1000 mcg is more than sufficient, especially now as cancer is being linked to the excess. So here is my simple question yet I can't find an answer to it anywhere..is it ok to take VB12 once a month or once every 3 weeks or once every 2 weeks. I think many would benefit from a straight answer or is there no real information because nobody knows. Once a month seems a long time but what if I said once every 2 months..3, 4 5, 6 etc. I need an answer. Thank you
If b12 high, then what need to do?
Hello, I have 2,500 sublingual methylcobalamin tablets I take once a week. Is it safe to cut the it in half so I can get the dose recommended by Dr. klaper? I see here that 2500 is too high.
Iâm staying far away from B12, it was an ingredient in the almond milk I used every morning. After a year my anxiety was so bad, head pressure ringing in ears, awful spasms and nausea all day beginning after breakfast., I thought for sure I had brain tumor. Stopped the milk and instantly felt normal again. Been vegetarian with no eggs for 32 yrs and my B12 level is normal anyway.
Strange. There's not enough b12 in almond milk to do that. Glad you're better though!
Definitely wasn't the b12
Whereâs your scientific evidence that your anxiety was linked to vitamin B12? Weâd like to review it. Vitamin B12 is water soluble. You simply pee out any you donât need; Thanks.
almonds have the MOST toxic herbicide sprayed on them vs any other nut; so i stopped using almond milk and have been using cashew milk ever since. and wheat is drenched in glyphosate toxic herbicide just before harvest, I get aching swollen joints when i eat it.
@@Lauren-vd4qe Cashews are grown in other countries, like the Middle Eastern countries, India, Vietnam and other Southeast Asian countries. Brazil also. Why would you imagine they donât use highly toxic pesticides? They are totally unregulated. They use pesticides that are banned in the U.S. and Europe. These countries, and China, use tons of toxic pesticides in their tea plantations. Thatâs why you should only buy Organically grown black and green teas from reputable companies.
I have 5000 mcg B12 tablets should I take once a week or every other day ??
I personally take this same dose every day
The Nerve Doctors on yt, address up to date relevance on these topics.
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.
HI, are you feeling better?

This does not make any sense. 5-10mkg daily is 35-70mkg weekly. But 500-1000mkg once or twice a week is 500-2000mkg weekly.
Thanks for the information. Have you ever explained the ratio of colestral is ratio significantl many thanks
Some green algee have b12
I read that too much vitamin b12 intake depletes your potassium levels and vise versa, anybody heard of this?
Hm Ive had low potassium symptoms so that makes sense.
nice exactly what i take. 500mg twice a week.
How about Vitamine D suplement for vegan that live in dark winter country? i heard its kinda good for winter without much sun right?
I take 2500 micrograms once per week.
take both just incase i say, 1000 twice a week, one on one day and the other 3 or 4 days later, cant lose that way, grow some carrots and radishes aswel, probiotics
Let me tell you about those vitamins you whayst you're money on those things they're all are junk special those gummies one when you try to get some out the can they don't come out you have to put a dinamite to ge out of the things
But even too little vitamin B12 can increase the risk of cancer.

too high B12 may cause liver cancer
this is CRAZY !!
why you are NOT TALKING about to do - BLOOD TEST !!??

Not necessary
The reason why is because of the test shows you are low in b12 you need to take a b12 daily. And if you are not low in B12. Take a b12 daily.
