Vitamin B-12 is a water soluble vitamin necessary for the maintenance of a healthy nervous system and for the metabolic utilization of fats and proteins.&ampnbsp; 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.&ampnbsp; In addition, adequate intake of Vitamin B-12, along with Folic Acid and Vitamin B-6, encourages healthy serum homocysteine levels, thereby supporting cardiovascular health.&ampnbsp; Because Vitamin B-12 is found predominantly in animal products, strict vegetarians are at risk of developing Vitamin B-12 deficiency and may benefit from supplementation.*&ampnbsp; NOW&ampreg; Vitamin B-12 is vegetarian/vegan (non-animal derived).
