Vitamin B3 (Niacinamide) promotes proper circulation and healthy skin. In the body, it forms a co-enzyme which is essential for the metabolism of carbohydrates, fats and proteins in all cells. Niacinamide is involved in the synthesis of bile salts required for the digestion of fats and the absorption of fat-soluble nutrients, as well as regulates the synthesis of hormones, insulin and thyroxine. Trophic's Niacinamide does not produce the characteristic niacin flush.
