Product Information


Andrew Lessman's NAC 500 delivers 500 mg of N-Acetyl Cysteine (NAC), an essential glutathione precursor and detoxifying antioxidant that is a uniquely active form of the conditionally essential amino acid cysteine. It is the sulfur in cysteine's “thiol” (sulfhydryl) group that imparts NAC's unique properties, including its critical role as a building block of Glutathione – our body's most powerful, internally-produced protective compound. NAC offers important protection to the brain, heart and lungs, but because of its unique detoxifying role, NAC provides targeted protection to the hardworking cells of the liver and kidneys making it a sensible part of any internal cleanse or detoxification program. Unfortunately, NAC is not readily available from the diet and it cannot be readily produced by the body, so supplementation is a straightforward way of promoting its protective benefits. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
