N-ACETYL-CYSTEINE (NAC) is an amino acid that is a precursor to glutathione, the body’s most powerful antioxidant, which helps promote optimal detoxification. NAC is heavily researched for its role in optimising lung health, and is also used for rapid recovery after workouts. It may also beneficial for protection against normal exposure to heavy metals.

Designs for Health offers N-Acetyl-L-Cysteine in 900 mg per one capsule serving. N-Acetyl-L-Cysteine (NAC) is a potent amino acid precursor to glutathione (GSH), one of the body’s most powerful intracellular antioxidants, which supports optimal phase II liver detoxification. It is the most stable nutritional supplement form of the amino acid L-cysteine. NAC also plays a critical role in supporting lung health for respiration, is used for rapid muscle recovery post-workout, and protects against a vast array of pro-oxidative insults and inflammation.

Furthermore, due to the presence of a sulfhydryl group (-SH), NAC is beneficial for protection against exposure to heavy metals and other harmful toxicants. NAC is prominently found in Allium plant species, especially onions, and is more bioavailable than supplemental glutathione (GSH) itself.
