B12 absorption is a complicated process. The human body cannot synthesize vitamin B12 on its own. Here are the main steps in the absorption process: After ingestion, B12 is separated from its food source (proteins) by hydrochloric acid which is secreted in the digestive tract. B12 then binds itself to a molecule in the stomach known as the “intrinsic factor”. It is this union which allows B12 to be absorbed. The B12/intrinsic factor complex will then travel throughout the intestine before finally being absorbed in the ileum (the end of the small intestine). Who should take a supplement? Vegetarians: Vitamin B12 is mainly present in animal products. Certain vegetal sources (miso, spirulina) do contain some B12 but in a form that is only slightly absorbed by the body. People over age 50: 10 to 30 % of these people do not assimilate B12 due to low gastric acid levels. Persons affected by autoimmune diseases: self antigens will bond to the intrinsic factor rendering it unavailable for the B12.
