Vitamin B-12 (Cyanocobalamin) is a water soluble vitamin necessary for the maintenance of a healthy nervous system and for the production of energy from fats and proteins. Vitamin B-12 is also essential for the synthesis of DNA during cell division and therefore is especially important for rapidly multiplying cells, such as blood cells. In addition, adequate intake of Vitamin B-12, along with Folic Acid is critical for the conversion of homocysteine to methionine, thereby supporting a healthy cardiovascular system. Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body. While B-12 is stored in the liver, dietary sources are of animal origin only (meat and dairy). Therefore, supplementation with B-12 may be especially important for strict vegetarians.
