The Active Ingredient Is: N-acetylcysteine (NAC)

N-acetylcysteine, or NAC, is a reliable supplemental form of the conditionally essential amino acid L-cysteine. It serves as the sole active ingredient in this product and is used as a handy source of cysteine for the body.

This form is bioavailable and acts as a precursor to glutathione, supporting the body's antioxidant capacity and cellular defence mechanisms.

What Does N-acetylcysteine Do?

NAC contributes to the production of glutathione, a major intracellular antioxidant that helps maintain cellular redox balance. It also supports immune function and may aid in detoxification processes, with mucolytic properties noted in some respiratory contexts.

EFSA-informed understanding describes amino acids like NAC as supporting normal antioxidant function and physiological defence, aligned with general health maintenance.
