NOW Supplements Niacin Vitamin B 3 500 mg Flush Free Double Strength Nutritional Health 90 Veg Capsules

Niacin (vitamin B-3) is an essential B-complex vitamin. Flush-free niacin contains inositol hexanicotinate, a form of niacin that consists of six molecules of niacin linked to a single inositol molecule. It is slowly broken down in the body to yield free niacin and inositol. This gradual release of niacin allows for true niacin activity without the characteristic niacin flush that many people cannot tolerate. Natural color variation may occur in this product.
