L-Glutathione (often referred to simply as glutathione, or GSH) is a naturally occurring tripeptide made from the amino acids glutamate, cysteine, and glycine.
It is one of the body’s most important antioxidants, protecting cells from oxidative stress, regulating detoxification, and supporting immune function.
In research settings, glutathione is widely studied for its role in redox biology, aging, cellular repair, and metabolic resilience.
