 Glutathione, GSH, is a powerful antioxidant found in all living cells. It is essential for maintaining healthy cells and tissues, and plays a key role in the body's ability to fight off disease. GSH is produced in the liver and distributed throughout the body, where it helps neutralize harmful free radicals and other toxic substances. Additionally, GSH is involved in many other important cellular processes such as protein synthesis, DNA repair, and cell growth.
