Supports formation of the key antioxidant compound glutathione Provides antioxidant support Provides the three precursors needed to form glutathione within the body: N-acetyl-L-cysteine (NAC), glutamic acid and glycine Includes a-lipoic acid Glutathione Precursors provides antioxidant support and supports glutathione formation. Glutathione, or (GSH), is the primary intracellular antioxidant involved in preventing lipid and protein oxidation, and is a critical component in the enzymatic process used to detoxify hydroxide peroxide (H2O2). Cysteine, glutamic acid and glycine are the three essential precursors for endogenous glutathione production. Supplementation with NAC, cysteine, and glycine has been shown to increase GSH levels.Serving Size:1 Vegetable CapsuleServings Per Container:30Amount Per ServingN-acetyl-L-cysteine (NAC)200 mgL-glutamic acid200 mgDL-alpha lipoic acid200 mgL-glycine100 mgOther IngredientsHypromellose, magnesium stearateSuggested UseTake 1 capsule daily with a meal or as recommended by your health professional.WarningIf you are pregnant or lactating, have any health condition or are taking any medication, consult your health professional before use.
