Glutathione

Glutathione is a vital antioxidant produced naturally in the liver from amino acids (glycine, cysteine, glutamate), crucial for tissue repair, immune function, and detoxification. It combats oxidative stress, potentially aiding conditions like liver disease and neurodegenerative disorders. Administered orally, intravenously, or topically, it is used for skin lightening and health optimization, though high-quality evidence for many uses is limited.
