  • @daytonadudenheimer Listen again from 2:45 onward.

  • So why are 31% of Americans B12 deficient when 31% of Americans aren't vegan?

  • @asnoethias Correct. Most of the gut flora are within the colon but B12 is not very well absorbed, if at all, within the colon.

  • @benjorgensen1 - good question. The answer is to eat unwashed (i.e. bacteria-laden) fruits and veggies. But while some bacteria is good for us, other bacteria is bad for us. So supplementation is pragmatic: by reverting to 'advantages' of less purified foods, we then re-introduce the bigger risk of all manner of other diseases. (Which in fact are now elevated by the fact that many factory farmed veggies are further contaminated by animal waste).

  • B12 is made in the human body by bacteria as well. It's the absorption that is debated, and may vary by individual.

  • yes, well... what is a NATURAL fix for this problem? one shouldn't have to be dependant on any pills. i have constantly hunted for the truth behind b12 and all i ever get is "take a suplement", and now that we know that eating animal porducts is not a sure deal, we have an even bigger problem. i hear that eating enough meat to get b12 will be unhealthy amounts of animal protein and other things. talk about some acidity! catch 22!

  • And remember that 99% of cases of B12 deficiency are seen in meat eaters; also B12 deficiency was first discovered in meat eaters. See Could It Be B12: An Epidemic of Misdiagnoses by Sally Pacholok and Jeffrey Stuart MD

  • "Bacteria make B12!"

    I just love that quote.

  • The "you must eat animal products to prevent vitamin B12 deficiency" myth has been debunked by John A. McDougall, M.D.

    Thank you!

  • @redshiftexperiment There is no side affect, its water soluble so you pee it out. Its like taking too much vitamin c, doesn't happen. You need 250 mcg per day minimum. Visit nutritionfacts DAWT org and search b12, you will see science based recommendations based on the latest research.

  • @HrapovikPlush We create b12 in the lower part of our intestines and it does not get absorbed because it is too low. This is common nutritional knowledge

  • My husband eats meat fish and poultry heavily and was told he has a B12 deficiency , I am a vegan and my B12 is fine. I think it's just common sense to have your blood checked 1or2 times a year that way you can protect yourself. Each person needs to follow their own body signals. We are all individuals
