Glutathione is an antioxidant formed from the amino acid cysteine, glutamate and glycine. Virtually all your cells have glutathione, but this antioxidant is most highly concentrated in your liver, pancreas, spleen and eyes. Your glutathione levels dwindle as you age. Taking glutathione supplements may offset the reduced glutathione levels caused by age. Glutathione supplements may be administered intravenously. You can also take glutathione supplements in oral form or via nebulizer. No known side effects are associated with injections of glutathione. Glutathione is primarily responsible for reducing the levels of cysteine on the surface of proteins and helps protect your body from free-radical damage.
