2. What Is Glutathione?

Glutathione (GSH) is an endogenous antioxidant found in almost all living cells. It plays a central role in cellular redox balance, detoxification pathways, and maintenance of oxidative stability. In industrial applications, reduced L-glutathione is preferred due to its bioactive form and higher functional value.
