Niacinamide (Vitamin B-3) is a form of niacin, a water soluble B-Vitamin. It is a derivative of niacin that does not cause the "flush" normally associated with taking high doses of niacin. Niacinamide is readily converted into the bioactive forms of Niacin, NAD+, NADH, NADP, and NADPH, which are vital cofactors in cellular energy production and are critical for the maintenance of DNA stability.*

Niacinamide and niacin are two different forms of vitamin B-3. Niacinamide does not cause a niacin flush.
