I was recently at Summerfest. I heard a lot of nutrition lectures from Dr. Michael Klapper, Dr. Michael Gregor ( veganmd.com ), Brenda Davis RD, and George Eisman RD.
Dr. Klapper has been running a vegan health study. He warned us that he has been seeing a lot of vegans with cardiovascular disease, neurological damage, and compromised cognition due to b-12 deficiencies( vegetarians have also been victims ).
The other experts noted similar experiences.
They all agreed that unless you live in Israel ( foods are fortified with b-12 by law ) there are only two reliable sources of vitamin b -12:
1. Foods that are labeled as being fortified with b-12
( may not have enough per serving )
2. Vitamin B-12 supplements
Dr. Gregor recommended that if you have been a vegan for over a year
( even if you have been eating fortified soy or nutritional yeast ) that you take a 2000 mcg sublingual b-12 pill everyday for two weeks and then once a week indefinately.
All of the experts added that getting b-12 in multivitamins may not work as well as sublingual pills as proper utilization of b-12 starts in the mouth and continues in the stomach. Most large vitamin pills do not break up until they reach the gut.
They recomended holding a b-12 pill under your tounge until it dissolves and taking it with no other supplements.
