The Active Ingredient Is: N-Acetylcysteine (NAC)

N-Acetylcysteine is a stable form of the amino acid cysteine and functions as a precursor to the body’s master antioxidant, glutathione.

This form is commonly used to support cellular defence and detoxification processes, with NAC acting to promote glutathione production in the body.

What Does N-Acetylcysteine Do?

NAC participates in supporting antioxidant defence and detoxification pathways, contributing to normal cellular protection and redox balance. It plays a role in glutathione synthesis, aligning with EFSA and NHS guidance on antioxidant nutrients.

Studies indicate NAC can help maintain glutathione levels within the normal range, contributing to overall cellular resilience. This interpretation is aligned with expert reviews from researchers at recognised universities.
