Glutathione is a powerful tripeptide antioxidant composed of glutamine, cysteine, and glycine. It is naturally produced in every cell of the body and plays a critical role in neutralizing free radicals, supporting immune function, and facilitating detoxification. Glutathione is essential for maintaining cellular health and has been studied for its role in reducing oxidative stress, supporting liver function, and promoting skin health. Research suggests that supplemental glutathione may help brighten skin tone, reduce the appearance of dark spots, and support overall radiance by modulating melanin production. It also works synergistically with Vitamin C to enhance antioxidant defense.
