Vitamin B-12 (Cyanocobalamin) is a water soluble vitamin necessary for the maintenance of a healthy nervous system and for the metabolic utilization of 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 and Vitamin B6, supports healthy serum homocysteine levels already within the normal range thereby supporting cardiovascular health. Because Vitamin B-12 is found predominantly in animal products strict vegetarians are at resk of developing Vitamin B-12 deficiency and may benefit from supplementation.
