Glutathione, Cysteine & C

Life Extension, Ft. Lauderdale, FL, has introduced Glutathione, Cysteine & C, a dietary supplement formula that contains 50 mg of Setria glutathione, along with vitamin C. Glutathione (gamma-L-glutamyl-L-cysteinyl-glycine) is a peptide-like (short-protein) molecule synthesized in the body from the three amino acids: L-glutamic acid, L-cysteine and glycine. Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione.
