I read this on the NIH website. Is it true that, by eating foods fortified with b12, one can overcome the problem of insufficient stomach acid? Is so, why would one need injections. In addition, does this mean that b12 in tablet form will also be absorbed?
‘Vitamin B12, bound to protein in food, is released by the activity of hydrochloric acid and gastric protease in the stomach . When synthetic vitamin B12 is added to fortified foods and dietary supplements, it is already in free form and, thus, does not require this separation step. ‘
