Reduced Glutathione: glutathione acts as one of the major detoxifiers in the body, but it must be in the reduced form to work properly. Sometimes glutathione will be listed on the label of a product, however it wont be specifically listed as being reduced. The unreduced form is much cheaper and isn’t metabolically active. Riboflavin, niacinamide, selenium, lipoic acid and glutathione reductase are all essential cofactors for generating reduced glutathione. Once the cysteine moieties become oxidized, they combine to form cystine. Cystine taken by itself is poorly absorbed.

Glutathione (GSH) is a tripeptide. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side chain. Glutathione, an antioxidant, protects cells from toxins such as free radicals.
