Supports formation of the key antioxidant compound glutathione. Provides the three precursors needed to form glutathione within the body: N-acetyl-L-cysteine (NAC), glutamic acid and glycine. Includes alpha-lipoic acid. Helps to protect against oxidative stress and supports glutathione formation. Glutathione, or -glutamyl-cysteinyl glycine (GSH), is the primary intracellular antioxidant involved in preventing lipid and protein oxidation, and is a critical component in the enzymatic processes. 1,2 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.
