Because stomach acid is required for the release of vitamin B 12 from the proteins in food, vitamin B 12 absorption is diminished. Decreased stomach acid production also provides an environment conducive to the overgrowth of anaerobic bacteria in the stomach, which further interferes with vitamin B 12 absorption . Because vitamin B 12 in supplements is not bound to protein, and because intrinsic factor (IF) is still available, the absorption of supplemental vitamin B 12 is not reduced as it is in pernicious anemia.
