Source Naturals L-Cysteine Powder (3.53 Oz) #10080392

L-Cysteine is a crystalline free-form amino acid that is active in many body processes. L-Cysteine works in the liver to protect the body from harmful substances and may help to prevent oxidation of tissues. L-Cysteine, along with L-Glutamic Acid and Glycine, is the rate-limiting precursor in the synthesis of glutathione peroxidase (one of the body’s main antioxidant enzymes), which minimizes lipid peroxidation (fats turning rancid).
