N-Acetyl-L-Cysteine (NAC) 600 mg, 60 capsules is listed by Life Extension under Item # 01534 with UPC 737870154365. The page describes NAC as an easily-absorbed nutrient with robust benefits for immune, bronchial, respiratory and liver health. Its overview states that N-acetyl-L-cysteine supports immune function, bronchial and respiratory health and liver health, and that it is a precursor to glutathione, a powerful antioxidant in the body that protects cells from free radical damage. The page lists three benefits: support for immune, bronchial and respiratory health; encouragement of liver health and function; and powerful antioxidant action that protects against oxidative stress. A section titled Fight Back Against Oxidizing Free-Radicals explains that N-acetyl-L-cysteine is a precursor to glutathione, which helps protect cells from oxidative stress, and that it offers support for immune function, lung and liver health and protects against insults from foreign compounds. The product details say N-acetyl-L-cysteine supports healthy respiratory function as well as bronchial health, encourages healthy liver function and promotes immune system health, and that numerous placebo-controlled studies suggest supplementation can favorably affect well-being and quality of life. The page cites references in journals including Antioxidants, Ann Palliat Med, Adv Ther, Free Radic Biol Med, Indian J Tuberc and Curr Opin Pharmacol.
