Allergy Research Group No-Flush Niacin is a dietary supplement providing niacin for many functions in the body. No-Flush Niacin supports the use of proteins, carbohydrates and fats in the body; is important to nervous system functioning; supports sex and stress related hormone production; and is important for healthy liver, eyes, circulation, skin, and hair. The body is unable to store niacin so it must be obtained from diet or supplementation. This formulation provides niacin with inositol which, when taken orally, causes the niacin to release slowly minimizing the "niacin flush" common in regular niacin supplements.
