About





            

                
NAC is a precursor to glutathione that provides cysteine for glutathione synthesis and directly scavenges reactive oxygen species. A controlled trial found NAC (1,200 mg/day) reduced melanin index. NAC is sometimes used as an alternative to direct glutathione supplementation, which has questionable oral bioavailability.

            

        

        

        
        
        

            

  
How It Works





            

                
Precursor to glutathione (the body's master antioxidant); provides cysteine for glutathione synthesis; directly scavenges reactive oxygen species; mucolytic properties; may modulate NF-kB signaling and reduce inflammatory mediators implicated in acne, eczema, and skin aging.
