Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in the metabolism of every cell of the human body.
It is one of eight B vitamins. It is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the maturation of developing red blood cells in the bone marrow.
