L-Glutathione Reduced is a tripeptide composed of glutamine, cysteine, and glycine, present in cells as a vital antioxidant. It appears as a white to off-white crystalline powder and plays a key role in protecting cells from oxidative stress by neutralizing free radicals and reactive oxygen species. Reduced glutathione (GSH) is the active form that participates in cellular detoxification, immune support, and regeneration of other antioxidants. It is widely used in pharmaceutical, cosmetic, and food industries due to its potent antioxidant properties and skin-brightening effects.
