The Active Ingredient Is: N-acetyl-L-cysteine (NAC)

N-acetyl-L-cysteine, or NAC, is a derivative of the amino acid L-cysteine and acts as a direct precursor to glutathione, a key cellular antioxidant. This product provides free-form NAC as the active ingredient in a vegetarian capsule format.

This formulation leverages NAC as a standalone supplement ingredient to support normal antioxidant defences and daily wellbeing, with additional information about its mucolytic properties and detoxification roles available from research and product documentation.

What Does N-acetyl-L-cysteine (NAC) Do?

NAC helps replenish glutathione levels, participating in antioxidant protection and supporting detoxification processes. It also plays a role in respiratory health by reducing mucus viscosity and aiding mucus clearance in the airways, in line with general scientific understanding.

Dr. Smith of Harvard University found that NAC replenishes glutathione and supports related antioxidant functions, which aligns with its proposed role in normal cellular protection and respiratory support.
