N-Acetyl-Cysteine (NAC) is a source of the conditionally essential amino acid L-cysteine and a precursor to the tripeptide glutathione. NAC and glutathione support antioxidant and detoxification activity in the body.*

NAC (N-acetyl cysteine) supports the body's antioxidant defenses by boosting glutathione levels, which helps protect cells from oxidative stress and damage. It promotes respiratory health by thinning mucus, making it easier to clear the airways in conditions like bronchitis or COPD. NAC also supports liver detoxification and has shown potential benefits for brain health, mood regulation, and immune function.
