SISU NAC 600mg Details

To help relieve symptoms of chronic bronchitis. To help reduce symptoms of respiratory infection and support the immune system for those over 65 or suffering from chronic degenerative diseases.

The familiar symptoms of cold and flu including head and body aches, sinus and chest congestion, and coughing and sneezing, are all indications that the cold or flu virus has significantly multiplied and your body is working to expel it and destroy affected cells. Over-the-counter drugs are only partly effective at suppressing only some of the symptoms and are associated with negative side effects. You can prevent respiratory infections from starting by boosting your immune system with NAC (N-acetyl-L-cysteine). Research shows that even if you do get a cold or the flu, NAC significantly decreases the severity of symptoms. NAC helps to increase levels of glutathione, which is considered the “master antioxidant” in the body and an important part of your cold defense system. Boosted by NAC, glutathione helps to protect your lungs against respiratory illness. NAC also decreases the frequency of flare-ups and symptoms of chronic bronchitis.
