> What do vegans do for vitamin B12? Huge can of worms you're opening up there, Jerry. It never seems to get settled, but basically, there are some who say that B12 is in some fermented vegan products and/or algae, while others say that those are just B12 analogs (or analogues) that don't do the job. If they're smart, IMHO, vegans take B12 supplements. If I were you, I'd do some research instead of asking about it here. Below are two links that discuss B12 analogs and one that's just plain interesting. :) Carol http://www.vnv.org.au/Nutrients/VitaminB12.htm http://www.scienzavegetariana.it/rubriche/cong2002/vegcon_B12_en.html http://www.lifelinknet.com/siteResources/ArchivePages/Methylcobalamin. asp
