Nicotinamide
Nicotinamide is an amide form of vitamin B3 that is incorporated into NAD and NADP as oxidation-reduction coenzymes. Nicotinamide exhibits anti-inflammatory and anxiolytic activities; it is clinically used to treat acne vulgaris and rosacea. Commercially, nicotinamide is used in skin whitening treatments as it decreases skin pigmentation. Nicotinamide also binds GABA receptors, decreasing aggressive behavior.
