Glutathione is a tripeptide composed of the amino acids glycine, cysteine, and glutamic acid. It is produced by the liver and nerve cells in the central nervous system and is found in every cell in the body. Glutathione is an antioxidant that helps prevent damage to important cellular components caused by sources such as reactive oxygen species, free radicals, peroxides, lipid peroxides, and heavy metals. It is involved in many body processes, including tissue building and repair, making chemicals and proteins needed in the body, and immune system function.
