I read years ago that the liver can store five years of vitamin b12. Unless you are having sex, as a man, you lose a lot of b12 in the sexual fluids. MH says a lot, that unwashed, raw fruits have plenty of beneficial vitamins on them. Have you tried that?
Also, MH what about naturally fermented fruits, does the natural alcohol/vinegars contain stuff that you wouldn't normally get? Does anybody have a guess what color vibration b12 would be?? Thanks.
