The Active Ingredient Is: N-Acetyl Cysteine (NAC)

N-Acetyl Cysteine, or NAC, is a steady derivative of the amino acid cysteine and acts as a dietary supplement to help support body defences. This form is commonly supplied in vegetarian capsules to offer a handy NAC source for daily use.

NAC is valued for its knack to replenish intracellular glutathione, a key cellular antioxidant that helps shield cells from oxidative damage and environmental toxins.

What Does N-Acetyl Cysteine Do?

NAC helps replenish glutathione, the body’s master antioxidant, supporting normal antioxidant and detoxification processes. Scientific evidence suggests potential benefits for immune resilience and liver-related functions when used as part of a broader health approach, with clinical exploration at different intake levels.

Dr. Tse from University found that NAC at certain dosages can cut COPD flare-ups and help small-airway function, illustrating its role in supporting normal respiratory health mechanisms.
