NAC (N-Acetyl-L-Cysteine)

NAC is a precursor to glutathione, an amino acid renowned for its powerful antioxidant properties. NAC supplements help maintain, support and enhance the immune system. NAC has positive effects on the mucosal membranes of the sinuses and the lungs. Taken during sinus infections or upper respiratory infections, NAC shows promise in making coughs more productive and lessening the severity of these illnesses. Research has also revealed that NAC may be able to reduce some of the cellular damage found in ex-smokers by acting as a targeted antioxidant.
