The Glutathione Experts
Reduced L-glutathione, most commonly called glutathione or GSH, is the most powerful naturally occurring antioxidant in all human cells. We have developed this site to deliver information about this powerful antioxidant to consumers that are considering Glutathione.
It is a tripeptide composed of the amino acids glutamic acid, cysteine and glycine. Glutathione is found in all cells in the body, including the bile, the epithelial lining fluid of the lungs, and—at much smaller concentrations—in the blood.
The highest concentration of glutathione is found in the liver, making it critically important in the detoxification and elimination of free radicals. Accumulation of these dangerous compounds can result in oxidative stress, which occurs when the generation of free radicals in the body exceeds the body’s ability to neutralize and eliminate them. Free radicals are highly reactive compounds created in the body during normal metabolic functions; they can also enter the body through the environment.
Metabolically, glutathione has many functions. For example, glutathione plays a substantial role in the functioning of the body’s immune system. Its antioxidant property makes it vital to white blood cells (lymphocytes)—as it allows them to reach their full potential during the oxygen-requiring activity of the body’s immune response.
