Life Extension ~ Glutathione, Cysteine & C

NEW YORK–Life Extension® introduced Glutathione, Cysteine & C, formulated with 50 mg of Setria® Glutathione from Kyowa Hakko USA. 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. Glutathione is an antioxidant that helps detoxify xenobiotics. A major function of vitamin C is to keep glutathione in its reduced form so it can continue to provide free radical-quenching effects. L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids. 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, one of the body’s most important natural detoxifiers.
