N-Acetylcysteine, NAC, is a sulphur-rich amino acid derivative that functions as a precursor to the body's main antioxidant, glutathione.

This form delivers NAC as a readily absorbed source that supports antioxidant defences and detoxification processes in cells. This ingredient is usually supplied in supplement form for oral use.

What Does N-Acetylcysteine Do?

NAC is involved in replenishing glutathione levels, supporting the body's natural antioxidant system. It also contributes to replenishing intracellular cysteine, the rate-limiting precursor for glutathione synthesis, helping protect cells from oxidative stress. Its mucolytic action helps break disulfide bonds in mucus proteins, making secretions less viscous and easier to clear. This supports respiratory health in daily wellness contexts.

The primary benefits described reflect normal biological functions, emphasising antioxidant support and airway comfort within everyday health maintenance.
