Reduced L-glutathione, most commonly called glutathione or GSH, is often referred to as the body’s “master antioxidant”. Composed of glutamic acid, cysteine and glycine, this tripeptide helps to detoxify the body and neutralize free radicals while supporting the immune system. It is known for its role in providing antioxidant protection for the body’s tissues, including the arteries, brain, heart, liver, lungs, and skin. Glutathione levels decrease as the body ages.
All cells in the human body are capable of synthesizing glutathione. But the highest concentration of glutathione is found in the liver, making it critically important in the detoxification and elimination of free radicals. Free radicals are highly reactive compounds created in the body during normal metabolic functions; they can also enter the body through the environment. Accumulation of these 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.
