Vitamin B-12 - Dietary Sources

The vitamin can be supplied to the human body through diet that includes egg, fish, chicken, beef, fortified cereals and shell fish. There are some factors that play a major role in the absorption of this vitamin.

  • Stomach acid (and pancreatic enzyme) digests the food and thereby liberates the bound vitamin B-12.
  • A protein, called intrinsic factor (IF), binds to vitamin B-12, before it can be absorbed by the body through the small intestine.
