Product Details


L-cysteine HCL monohydrate (commonly known as cysteine) is an amino acid the body uses to make proteins. Although it is produced naturally, most cysteine comes from dietary sources. Cysteine is one of the main building blocks of glutathione, a powerful antioxidant the body produces to fight off free radicals and prevent cellular damage. Without enough dietary cysteine, glutathione levels drop (x).

In addition to its antioxidant boosting effects, research shows that cysteine may have a number of other health benefits. Studies suggest that it may reduce inflammation and improve digestion (x). Cysteine may also be able to improve immune function in patients with conditions such as HIV by stimulating infection-fighting cells in the body.
