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. Natural color variation may occur in this product. Review: Good - I start using this supplement for my hair and skin. It’s working fine. I haven’t finished it yet so I cannot leave a full review if it works or not I have to finish it and then I will be able to know if I will purchase more or no, but so far it’s not bad.
