Why Do We Need Liposomal Glutathione? Glutathione is a tripeptide made up of the amino acids: cysteine, glycine, and glutamic acid. It is known as the master antioxidant in the body. It has two forms: one is in an oxidized state, and the other is in a reduced state. The reduced form (GSH) is the active state and can neutralize free radicals in the body. Natural glutathione is primarily produced by our cells, though as we age, our bodies produce less and less. While a small amount of glutathione is available in certain foods, a high-quality, clinically researched liposomal glutathione supplement is the best way to increase glutathione within the body.
