Intrinsic factor facts for kids
Intrinsic factor (IF), or gastric intrinsic factor (GIF), is a glycoprotein. It is produced by the parietal cells of the stomach.
IF is necessary for the absorption of vitamin B12 (cobalamin) later on in the ileum of the small intestine. In humans, the gastric intrinsic factor protein is encoded by the GIF gene.
