What is Cysteine?



Cysteine is a sulfur-based amino acid found in the body and most high-protein foods. It is central to forming glutathione, a natural and potent antioxidant enzyme produced in the body.  As a result, cysteine has protective effects against free radical damage, along with immune boosting properties. When taken as a supplement, it is usually in the more stable and absorbable form of N-acetyl-L-cysteine (NAC). Other purported benefits have yet to be fully substantiated but there is no doubt that NAC is a valuable component for overall health, thanks to its ability to help reduce the levels of homocysteine and its powerful antioxidant properties.
