Niacin is an organic compound. It is a derivative of pyridine, with a carboxyl group at the 3-position. Niacin is a precursor to NAD+/NADH and NADP+/NADPH, which play essential metabolic roles in living cells. It is involved in both DNA repair, and the production of steroid hormones in the adrenal gland.
