One thing why do Vegans need B12 ….please add that to your videos so Meat eaters don't run with it . Btw meat eaters B12 used to come from drinking water but now that source is poisoned from man …Meat actually used to not be terrible for us especially fish but now it is ….anyways only true diet now is Vegan Reply l 800X says: July 15, 2015 at 11:34 am That explains why fern eaters are so looney : –B12, ++ homocysteine = shrunken brain. Reply Amir Amran says: July 15, 2015 at 11:35 am Conclusion: eat animals (no, i'm not talking about junk food way of making animal food), plenty of veggies – at least 4 a day, fruits nuts and seeds in moderation. sprouts and seaweeds here and there.

Thanks Reply dominicjan says: July 15, 2015 at 1:24 pm so now… whats the difference between suplementing with pills and injections. I sort of dont want to jab myself… Hope that pills are ok to use Reply nonchalantd says: July 15, 2015 at 1:47 pm We need to know at least one B-12 supplement that has been independently tested to be safe and to work because we know that many supplements don't even contain the ingredients listed on the bottle. Reply Loaded Mango says: July 15, 2015 at 1:52 pm time after time whole food plant based/vegan proves to be the healthiest way to go, I am so glad I saw the light!

Reply King Of Kings says: July 16, 2015 at 6:18 am Thats why I think many vegans are crazy. I thought it was because their estrogen was out of whack.. but this makes sense as well. Good job doc on the info. Reply viveutvivas says: July 17, 2015 at 4:47 am In other videos we've seen that fortified foods (i.e. fortified with cyanocobalamin) raises blood b12 levels in tests while failing to dependably reduce functional b12 deficiency, and failing to reduce uMMA. — We are then told we should just take more of the worthless Cyanocobalamin. I not convinced at all that cyanocobalamin can be effective for a majority of people. Why, if hydroxocobalamin scavenges cyanide, complexes with it, and is then eliminated with it … why would cyanocobalamin then be metabolized — where is the cyanide going? Why is it ineffective in many cases to reduce uMMA and homo-cysteine ? …. Couldn't then the hydroxo-changed-in-vitro to cyanocobalamin, then be again metabolized and the cyanide dealt with by other bodily means? – Please this is getting absurd! Which studies are high-priced lies/decoys and which are true? Unfortunately, it is so easy to promulgate crap studies… and everyone will run around buying things like chicken with the head cut off… and probably never realize it.(So many studies are also hiding what kind of b12 they are using…. worried all about which route of entry, they forget completely about what substance they are actually using)Conclusions:Cyanocobalamin is a dummy b12, designed to satisfy uncritical people and "newbs" … "yeah, the (fake)gold is in the pantry" she says, while she grabs the bag with the (real) gold and hops a flight out of town. Methylcobalamin? Some people can tolerate all those supplemented methyl groups.. but I could never stand it so far. … how much of these additional Methyl groups can the average consumer ingest without noticing how sickening it is and how it undermines basic mental comfort and ability? 2 trojan horses: methylcobalamin and cyanocobalamin —- methylcobalamin is primarily a methyl donor pretending to be just plain old cobalamin b12… (never mind that "methyl" thing — you need to get your b12 right away!) do we really want all those additional methyl groups in our diet… NO. Among other problems… note that methyl groups interfere with monoamine oxidase — which can then cause dopamine, nor-epinephrine, and serotonin to accumulate — Is this why people can no longer sleep as much after a few days of taking 2 mg a day of MethylCobalamin? "oh how wonderful… I have some methylB12 come and kick me in the head every morning at 5am, and them I'm WIDE awake! Isn't that wonderful? AND it's so cheap!" I might get Alzheimer's , so let me get brain damage NOW by ingesting tons of methyl groups. Dear Doctors…. please straighten out your understanding of and explanations of b12 and stop pretending about the effectiveness of non-hydroxocobalamin forms of this vitamin. So here's the hard pill to swallow for those who have a serious problem with homo-cysteine, uMMA, or functional b12 deficiency: The only form regarded as an actual medicine is Hydroxocobalamin — on the WHO list of most important medicines to have on hand. The other forms are at best useless for most people, but often harmful (methyl groups disturbing many body processes).

Reply TheStewieGriffinShow says: July 17, 2015 at 7:04 pm Coffee drinkers can have significantly higher levels of homocysteine. People who have higher levels of homocysteine also have an increased risk of heart problems. http://ajcn.nutrition.org/content/76/6/1244.full Reply TheStewieGriffinShow says: July 17, 2015 at 8:03 pm I wonder if anyone here is aware of all the toxic substances that are used in the making of vitamins and particularly B vitamins and/or what the formulas are? I will give you a little hint. It is NOT good. It always helps to know what you are putting in your body and especially if it's on a daily basis. Reply Dwight E Howell says: July 18, 2015 at 3:20 am Went to the local Kroger store Thursday night 7/17/2015. They didn't even have a can of peas on the shelves. Legumes are good and good for you but they are taking up less and less shelf space. Reply Daisy Cypress Tulipgarden says: July 18, 2015 at 4:32 am Methylcobalamin, B12 is probably the most nutritious form of B12.

Great video! Reply J Hancock says: July 23, 2015 at 7:59 am Dr. Greger, thanks for your videos, they are insightful and important for us concerned and curious about health. I've been a vegetarian for 22 years and recently turned vegan. In accordance with this video vitamin B12 was mentioned as an important supplement in preventing this harmful disease. However, it made me curious as to how often a vegan should take this vitamin (daily, once a week, etc) to receive it's minimal (or maximum) benefit. If you have any suggested literature or advice in relation to this that would be most helpful. Thank you. Reply Scotbot says: July 28, 2015 at 9:53 pm Interesting video. Did you also know that Methylsulfonylmethane (MSM) reduces Homocysteine levels? http://www.sciencedirect.com/science/article/pii/S1063458405002852 Reply pbunyon100 says: March 5, 2016 at 7:43 pm great video Reply johnny102marvin says: March 10, 2016 at 6:13 pm The more I listen to this channel the more raw vegetables I eat and the less meat I eat. I am down to eating just a few bites of meat every other day. But, I will start taking a B complex vitamin after listening to this video + sublingual vitamin B12 spray sold by NOW vitamin company. Reply Matt Bryan says: August 1, 2016 at 10:15 pm Wonderful video! Also if a person has genetic methylation issues they may need 5-MTHF (activated B9) to help reduce homocysteine. Reply Cookie Cutter says: May 25, 2017 at 10:51 am Anyone here got opinions on the best sources for B vitamins in general? They don't really seem to be present in a lot of the foods I eat :s Reply Redpill Progressive says: June 13, 2017 at 5:03 pm redo this video and stick to the facts. cut out cut out of them maybe this maybe that. if vegans have high homocysteine levels that means they had high methionine levels so this crap about just getting the methionine from animal products is just rubbish Reply John Paradise says: June 15, 2017 at 12:56 am "…and come out with the best levels of all!" Reply NICK COIN says: August 23, 2017 at 11:48 pm The Ohio State University Comprehensive Cancer CenterSummary:B vitamins are among the most popular supplements on the market in the United States. Some, like B6 and B12, are marketed and sold as products that can boost your energy. But a new study shows that using too much vitamin B6 and B12 dramatically increases lung cancer in men, particularly those who smoke.https://www.sciencedaily.com/releases/2017/08/170822175515.htmPS. If you are vegan as i am … take care… Reply yup says: January 13, 2018 at 7:17 am B12 comes With meat.. It's not From meat. It's from bacteria that lives in meat.. and pond water, dirt, etc. All vegans have to do is take a supplement to boost their chances against Alzheimers far beyond what meat eaters can get to.

Reply 58gennaro says: October 25, 2018 at 1:14 pm had a young lady respond to a post on a fb page that she is vegan for the animals health, not hers. i wonder if the stereotype of the unhealthy vegan is their own fault. zeal without knowledge. no thought to supplement what they may be missing. also goes for the keto group. i see many complaining about hair loss on keto. bottom line… do your research.

But what did humans eat, before they began living such artificial lives? Dr. Barry Groves 'What We Are Designed to Eat' provides some clues: https://www.youtube.com/watch?v=TlHz4T8JUyQ BTW, meat is an excellent source of the B vitamins, and vegetarians and vegans are often deficient. Is this a clue? Reply Debi tucker says: March 6, 2019 at 3:27 pm Hi , I was just wondering if you can get too much B12? I was taking a B Complex and an additional B12 and my levels were around 1300, so my Naturopath told me to stop taking the B12. I am over 60 and vegetarian so I was wondering if it is really a good idea to discontinue the B12, since age can be a factor in absorption.
