What’s the science of Vitamin B12?

Vitamin B12 is a water-soluble vitamin with a key role in the normal functioning of metabolism, as well as in the formation of red blood cells.

Vitamin B12 is naturally present only in animal products, where it’s bound to the protein in those foods. During digestion, the hydrochloric acid in your stomach releases Vitamin B12 from food, allowing the body to absorb it. People who do not eat animal foods and who don’t consume the suggested amount of Vitamin B12 from fortified foods and dietary supplements could have lower levels of Vitamin B12. As you age, the risk of inadequate Vitamin B12 intake may rise due to mal-absorption of the vitamin in the intestinal tract.
