Glutathione (GSH) is a tripeptide composed of glutamic acid, cysteine and glycine, containing sulfhydryl group, which has antioxidant and integrated detoxification effects. Glutathione can participate in biological transformation, thereby transforming harmful poisons into harmless substances in the body and excreting them out of the body. Glutathione also helps maintain normal immune system function.
