L-CYSTEINE Overview Information
L-cysteine is a type of amino acid, which are the building blocks of proteins. The body makes L-cysteine from another amino acid called methionine.
L-cysteine is naturally found in foods, but because it's made in the body it doesn't need to be consumed in the diet. L-cysteine has antioxidant effects and is used to make up antioxidants such as glutathione.
People use L-cysteine for cancer, diabetes, hangover, stroke, and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse L-cysteine with N-Acetyl Cysteine (NAC). These are not the same.
