What is l-glutathione reduced?

L-glutathione reduced (GSH) is a tripeptide molecule composed of three amino acids: glutamic acid, cysteine, and glycine. It is the reduced form of glutathione and serves an important role as an antioxidant in the body, protecting cells from oxidative damage caused by free radicals. GSH is also involved in detoxification processes, aiding the liver in breaking down and eliminating harmful substances from the body. Additionally, GSH plays a critical role in immune function, as well as protein synthesis and repair. It is available in supplement form and is commonly used for skin brightening and anti-aging purposes. However, its effectiveness in these areas is still a topic of debate, and more research is needed to fully understand its potential benefits.
