Vitamin B-12 (Cyanocobalamin) is a water soluble vitamin necessary for the maintenance of a healthy nervous system as well as for energy production from fats and protein. 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 and Vitamin B-6, supports healthy serum homocysteine levels, thereby sustaining a healthy cardiovascular system.*
