Antioxidant effects of melatonin

Melatonin supplementation is commonly recognized for its role in promoting sleep, but a growing body of research explores its broader impact on health, particularly through its potent antioxidant effects.
Early in-vitro studies (conducted outside living organisms) even suggest melatonin may be about twice as effective as α-tocopherol (vitamin E) in neutralizing free radicals under certain conditions. Its antioxidant function hinges directly upon the aromatic indole ring structure, which effectively neutralizes reactive oxygen species (ROS) and reactive nitrogen species (RNS). Through these direct interactions, melatonin generates metabolites that themselves participate in a cascade of antioxidative reactions, greatly amplifying its protective benefits.[1]
