Reduced Glutathione is an ubiquitous antioxidant involved in many cellular functions such as detoxification, amino acid transport, production of coenzymes and recycling of vitamins E and C. By serving as a critical nucleophilic scavenger, glutathione blocks free radical damage to all types of tissues. Glutathione is the most abundant intracellular thiol (sulfur-containing compound) and low molecular weight tripeptide found in living cells. Thiols such as glutathione, alpha lipoic acid and NAC are powerful sulfur-bearing antioxidants
