Glutathione is called a tripeptide as it consists of three amino acids, glutamic acid, cysteine and glycine. Since it can be formed from these three amino acids in the body, it is deemed non-essential, in that it does not have to be obtained from food. As cysteine is relatively rare in foodstuffs, it is this amino acid that is the rate-limiting factor in glutathione synthesis by the body. Lamberts® Glutathione Complex contains good levels of each amino acid as well as complete glutathione. Glutathione is found in all cells in the body, with the highest concentration being found in the liver. It forms the enzyme glutathione peroxidise which is one of the body’s most powerful antioxidants. Daily Intake: 1 to 3 capsules
