Definition

Intrinsic factor is a protein produced by glands in the stomach lining. It is necessary for the absorption of vitamin B-12 by the intestines.

A deficiency in intrinsic factor can cause pernicious anemia. Such deficiencies can be caused by surgical removal of the stomach, inherited conditions, or other diseases.
