Glutathione is a sulphur-containing peptide made up of three amino acids: Glutamic acid, Cysteine and Glycine. It is an important water-soluble antioxidant. Amino acids are the building blocks of protein. Glutamine is produced in the muscles and is distributed by the blood to the organs that need it. Glutamine might help gut function, the immune system, and other essential processes in the body, especially in times of stress. Glutathione, also referred to as L-Glutathione, L-gammaglutamyl, L-cysteinylglycine or GSH, is a tripeptide naturally occurring in the body. Existing in almost every cell of the body, Glutathione is a small molecule made up of three amino acids: cysteine, glycine, and glutamic acid. Glutathione, however, must be generated within the cells before it can work effectively within the body.
