Vitamin B12 Necessary for Arterial Health


45 Comments

  1. I watched a video of a girl who ate a vegan diet for 10 years and she started to get sick, after many doctor visits they found that she had depleated her micro nutrients down to a critical level, death would have occured next, she was critically close. She was eating an occasional egg and yogurt and that wasn't enough B12.

  2. this is why vegetarianism is not natural…

  3. The only person I know who is b12 deficient and needs injections is a 25 year old meat eater.

  4. Mechanized farming killed off most of the bacteria resp. for B12 in soil and the streams from which people used to drink. Studies have shown that produce grown in B12 enriched soil does not correct the deficit.
    Seriously. I don't understand the inability to comprehend this problem except.
    Hmm…
    …except that it shakes the faith too many have in the whole "Toxemia" religion and their rejection of medicine in general.
    Unfortunately no amount of science or personal suffering deters them.

  5. What foods are high in B12 if you're vegan, then? 🙁

  6. Most meat eaters take vitamins too

  7. I'm vegan. I take my B12. Why are so many vegans defensive about this?

    Meat eaters are at greatest risk if they have digestive tract problems. Vegans are at risk even if they have a perfect digestive tract. 

  8. I just don't believe it and think that B12 is much overrated. So I will move on with my vegan diet. Maybe it will kill me, maybe not. I know many more meat and/or dairy product eating people who need medical treatment than I know vegetarians or vegans. Thats all I need to know. Just my thoughts.

  9. Vitamins havnt changed much in all this time. Great way to make money though.

  10. So, how much B12 should I take then?

  11. Vitamin B12 deficiency in plant-based diets is a serious potential health hazard. If you missed this weeks video please watch and share: http://nutritionfacts.org/video/vitamin-b12-necessary-for-arterial-health/

  12. Have you did a study on Red Bull is this a good source of Vitamin B12 and do the other substances in it negate the B12 intake?

  13. I started taking B12 six months ago and felt mentally more alert but made several other dietary changes at the same time so I cannot be sure it was the B12 causing the positive effect

  14. Learn what b12 is, its made in our intestines, our food nowadays is too clean, FACT

  16. Stupendo video!

  17. Holy smoke!
    Dietary cholesterol does not directly relate serum cholesterol.
    This guy must work for the agricultural industry…

  18. Have there been any studies regarding delaying or reversing aortic stenosis. I am 64 years old and have been diagnosed with moderate stenosis and it seems surgery is the only solution

  19. If your a vegan then just take B12 supplements you need & be done with it. Then tell the meat promoters meat is not the ONLY way to get B12. You can get somewhere by riding a horse or by being dragged by a horse. You can get B12 by supplements or by who knows how many pounds or years of unnecessarily eating something that can harm you to get B12.

  20. I took b12 as a meat eater and I take it as a vegan. I train with many tour de france riders in Jan since 2003. Every single rider I have asked 'do you take b12 injections' they have all answered along the lines of 'yes of course, that is standard practice in any pro sport…'

    Good book to read is 'could it be b12?' by Sally Pacholok. She hates vegans but admits that eating meat for b12 sufficiency is 'extremely dangerous'.

  21. Love all your videos but these studies seem to be about post-menopausal women…so i was waiting to hear about how that fits into the mix. The video seems to take what is about a group of women and generalize it. Just asking.

  22. To those saying A) Dr Greger is bashing Veganism, or   B) Dr Greger doesn't think Veganism is healthy………..   Dr Greger IS a Vegan. He's a pretty clued up guy on nutrition, and he obviously believes Veganism to be the best. He's just pointing B12 out as one thing to watch out for.

  23. Just to be clear, B12 is a product of bacteria. High amounts of leafy greens will provide ample B12. Supplementation is just a more convenient option, since most people don't have a steady supply of quality greens, or the time to eat greens all day long. I just like to think about those big strong Gorillas in the wild eating a diet that consists of 80% leafy greens… no B12 deficiencies there… of course they probably eat termites and other insects (intentionally or otherwise) which are extremely high in B12.

  24. If eating a particular diet requires artificial supplements, then doesn't that indicate it isn't natural? I don't like to take any supplements if I can avoid it. Might it not be better to be a "mostly vegan" and eat a big serving of oysters for B12 and zinc once a week? Can animal products once a week meet our B12 needs for the rest of the time?

  25. Doesn't B-12 come from bacteria? Are there any other organisms that derive B-12 from other sources? I've read that this B-12 producing bacteria can be found on some organically grown plant foods, especially ones grown close to the ground such as carrots or lettuce, and with the modern way of growing crop the bacteria cannot live on conventionally grown foods. What's your opinion on this?

  26. you talk , like you are whining !!

  27. How then did humans survive in the wild (without supplementation)?

  28. what about Sea buckthorn?

  29. so where or how do we get B12 from?

  30. just take your b-12.

  31. human body makes B12. Doc please get on it.

  33. Dear Dr. Greger,
    Do Night Shade Plants contain molecules that block the absorbtion of B Vitamins?
    Thank you, David Larkin

  34. Dr. Greger my name is Sherrick Duncan I am a husband and a father of four.

    I worked hard and saved up and made payment for years and now own two acres in Oklahoma and am starting to grow my own food so that I can get off of food stamps and section8 welfare.

    I did all this so we can afford to eat a mostly plant based diet (I would do all plant based but it conflicts with my 100% self sufficiency self reliance prepper goals) so I have a question.

    If I eat like 98% plant based but only eat as much animal products as absolutely necessary to get a self sufficienct b12 source off of eithet eggs or whatever the best animal product b12 source is how much and how often maximum/minimum would one person need to ingest of animal product a week, month, year to get there necessary b12?

    I am absolutely 100% unwilling to do b12 injections or sublingual drops or foods or drinks that are fortified because (UNLESS I can grow or produce the b12 supplements myself) which from my studies I cant, then it violates my self sufficiency goal.

    So my question is what is the maximum/minimum amount of whatever the animal product highest in b12 would I need to eat how much and how often only to get my b12 needs from our farm raised animals?

    In other words I want to know how much of and what animal product that i can produce myself to eat to get all my b12 but little enough of this animal product to get the absolute minimum to no damage to my body or health?

    this paper shows that vitamin B12 deficiency is a lot more dangerous than we thought: it may create a new desease.

    Dr. Greger, don't you think that a partial consumption a type of meat with less satured fat as turkey would be good since it could avoid vitamin B12 deficiency?

  37. The Dead Sea contains 26 minerals, among which is COBALT (High in Vitamin B12).
    Could bathing in Dead Sea Salts be a more natural way to absorb vitamin B12?

  38. B12 deficiency is a silent epidemic with serious consequences to your health. Of all vitamin deficiencies, vitamin B12 deficiency is one of the most dangerous.This is the ONLY way to get B12 directly into your cells without injections->.https://dl.dropboxusercontent.com/u/591026868/VitaminB12/BestB12.html

  39. This study published in the Journal of Clinical Oncology suggests that B12 supplements may be harmful to men and particularly to male smokers. My husband and I are both vegan and taking supplements so I would like to hear what Dr Gregor has to say about it. http://ascopubs.org/doi/abs/10.1200/JCO.2017.72.7735

  40. I got my B12 from milk before going vegan and I get it from milk now… Nothing has changed, just the sugar and saturated fat content of the type of milk I drink.

  41. Will 2500 mcg once weekly be enough?  How will I know when its actually working?

  42. What about vegans who smoked taking high does of B12 and B6? https://cancer.osu.edu/news-and-media/news/long-term-high-dose-vitamin-b6-b12-use-associated-with-increased-lung-cancer-risk-among-men

  43. I've obtained a vegan diet for several months, take vegan vitamin supplement, exercise six days a week, drink plenty of water and green tea. However, I have an increase of spider veins in my legs and one vercrose vein in the back of my right leg. Every time, not just often, but every time I stand up I feel light headed. Also, I feel tired and fatigued.(Im not over weight either)What can I do to improve my blood circulation? Thank you!

  44. This is natures way of showing that an omnivore diet is more natural than one that excludes a certain food group.

  45. What is the BEST FOOD SOURCE for Vitamin B12 and the whole B-Complex ?
