ABOUT N-ACETYLCYSTEINE

N-acetylcysteine (NAC), an amino acid containing sulfur, is the acetylated form of L-cysteine. Cysteine is less bioavailable than acetylated cysteine.

 

The NAC increases body stores of L-cysteine, a molecule that is used in the production of glutathione, detoxification, and antioxidant molecule[1]. NAC's main mechanism of action[2] is its ability to support glutathione production. The availability of L-cysteine is thought to limit glutathione production (it is thought to be a rate-limiting[3] factor).

 

If the body is supplied with NAC, it can replenish glutathione levels in tissues throughout the body (including the brain, liver, and muscles) when the demand for glutathione has increased or when it is lowered (such as with older age or increased exposure to toxins). As both NAC and glycine are used in glutathione production, their combination makes sense[4,5].

 

This antioxidant promotes glutathione-related defenses, which lower the risk of free radical damage, metal, and toxic damage, as well as aging-related oxidative stress.
