N-Acetylcysteine Food supplement Liver/Detox Respiratory support Gluten free NSF-certified contents N-Acetylcysteine (NAC) is an amino acid that provides significant benefits by increasing the body’s production of glutathione and neutralising free radicals to support detoxification. NAC provides benefits throughout the body – from the lungs to the liver. This wide range of benefits is attributed to its direct antioxidant effects, its importance for replenishing glutathione, and its potential to break disulphide bonds. Why is this last point important? Because this is how it is able to break up mucus, thinning the secretions. NAC also binds toxic metabolites, increases blood flow to vital organs, and supports a balanced inflammatory response.
