N-Acetylcysteine (NAC) – Antioxidant, Liver, and Respiratory Support N-Acetylcysteine, commonly known as NAC, is a sulfur-containing amino acid that serves as a direct precursor to L-cysteine, one of the three amino acids required for the production of glutathione. Glutathione is the body’s primary antioxidant and plays a critical role in cellular protection and detoxification. In addition to its own antioxidant activity, NAC helps stimulate glutathione synthesis and supports the body’s natural detoxification processes, particularly in the liver. By supporting healthy liver function, NAC assists the body in managing oxidative stress and maintaining overall metabolic balance. NAC is also well known for its role in respiratory health. It helps thin and loosen mucus in the lungs, making it easier to clear through normal coughing. This action supports clear airways, healthy sinus function, and overall respiratory comfort. Research also suggests NAC plays a supportive role in immune function by helping the body maintain a balanced inflammatory response.
