Methionine, an essential sulfur amino acid, is involved in the synthesis of Cysteine, Glutathione, Carnitine, Taurine, Creatine, Nucleic Acids, Polyamines, Catecholamines and Protein. Low levels are noted in Glutathione deficiencies and alcohol-induced fatty livers. It may be beneficial to women with chronic urinary tract infections, and since Methionine is involved in protein synthesis, it is beneficial to trauma and burn patients, to increase nitrogen and assist in tissue repair.
