NAC + Glycine Powder ( 30 serv /159g) by Pure Encapsulations

Glutathione is one of the main endogenous antioxidants, acting in the body to recycle other antioxidants and protect the body from free radicals, as well as support detoxification. It is found in virtually every cell of the body and plays a critical role in cell function. Cysteine and glycine are necessary precursors for glutathione (GSH) synthesis, and co-supplementation of these nutrients promotes intracellular glutathione levels. The body requires amounts of cysteine and glycine that may not be met by dietary intake alone, particularly as we age. In a small study involving older individuals, two weeks of supplementation with N-acetyl-cysteine (NAC) and/or glycine indicated that the combination NAC + glycine raised red blood cell (RBC) glutathione levels more effectively than either amino acid alone. NAC and glycine have been shown to maintain healthy cytokine release during times of metabolic stress.‡
