Vitamin B-12 - Dietary Sources
The vitamin can be supplied to the human body through diet that includes
- 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.
