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.

Excellent Antioxidant! After reading an article in one of the women's magazines I subscribe to about NAC, I decided to try Andrew's NAC. The article indicates "This amino acid increases levels of glutathione, a powerful liver antioxidant that repairs damaged liver cells & stimulates the organ's detox processes to speed toxin removal & boost fat burning. Another plus, in a study in the Journal of Molecular Medicine, subjects who took NAC lost 5% of their body fat (about 10 lbs. for a 200-pound woman) over 8 weeks without making any other changes to your diet." Well, NAC coupled with Andrew's Liver Antioxidant Extract capsules have worked for me - I've lost 3 lbs. without any effort or changing my diet - great! In taking NAC and the Liver Antioxidant Extract capsules, they obviously stimulate the liver's detox processes as mentioned in the article.

Love this stuff! This is sort of a strange supplement. I had never heard of it, and when I read about it, it seemed important. I feel better since taking it, and notice a difference if I do not take it. I was happy to read the other review that mentioned being able to stop smoking using this product, because now I know where this sudden distaste for smoking might have come. I am not saying this is what did it, however shortly after I started taking this, I began to lose interest in smoking and no other variables were present. Wow. Thanks Andrew.

I have quit smoking Ok I know that a lot of you have quit smoking or do not I did !!!. for me . I was having so many problems and lighheadness and so forth . I started taking this product , and I kid-you-not .. it helped me feel better right away not a day later , I then did the 5 favorites that Lessman has to and the other produtcs later , but I have QUIT SMOKING AFTER 33 YEAR .... Ok !! I figured it was worth a try and I bought this one only taking this at the time ,, so and I do not take anything lightly when it come to what a lot of people sell out there and I do my homework and I really hope this will help someone like it helped me that smokes out there . it did help me more than you will ever guess . I tried everything till I found you can feel better , what freedom I have now ...
