Vitamin B12 (cobalamin) is an important nutrient for animal health because of its role in metabolizing nucleic acids (e.g., DNA) and forming proteins from amino acids. It also helps the body process fats and carbohydrates, and is used by the liver to make glucose.

Cobalamin interacts with folic acid in several interesting ways:

Vitamin B12 modifies folic acid so that the cells can use it.
The two vitamins work together to produce certain essential amino acids.
Both vitamins play a role in manufacturing red blood cells.
