For the most part, the B vitamins are absorbed directly into the bloodstream in your stomach or small intestines. The exception is vitamin B-12, which must be bound to something called intrinsic factor for absorption.
Absorption of most of the B vitamins happens further down in the small intestine, in the ileum. The other type of vitamin, the fat-soluble ones such as A, D, E and K, need to dissolve in fat before they can make it into the body.The process requires fat-digesting bile acids that come from the liver and live in the small intestine.hen the bile acids break down the fat the vitamins are dissolved in, the vitamins move with the fat through the intestinal wall, into the body, and finally end up in the liver and in body fat, where they're stored until they're needed (much like fat).
