Overview

Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach that is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine. When vitamin B12 is provided in combination with intrinsic factor, intrinsic factor reduces protease degradation and increases absorption of Vitamin B12.

Intrinsic factor is not currently available in any FDA or Health Canada approved products. However, it is currently in the marketed (but unapproved) product Hematogen in combination with cyanocobalamin (synthetic Vitamin B12), ferrous fumarate, and ascorbic acid for the treatment of anemias responsive to oral iron therapy.
