Love this product

My husband and I have been taking NAC 500 for many years. During Covid we got Covid but did not know it because we had no symptoms. We found out when we had lab work done. We give NAC all the credit for us staying healthy during Covid. One of the Doctors on a popular news channel recommended taking this product. We were very happy to hear this as we had been taking it for years and will continue to do so.

Product Description


Andrew Lessman NAC-500 N-Acetyl Cysteine
Andrew Lessman's NAC-500 delivers 500 mg of N-Acetyl Cysteine (NAC), a unique detoxifying antioxidant that is a special active form of the amino acid cysteine.
It is the sulfur in cysteine's "thiol" (sulfhydryl) group that imparts NAC's unique properties, including its vital role as one of the three critical building blocks of glutathione, which is our body's most powerful, protective and predominant internal antioxidant. Since glutathione cannot cross cell membranes and cannot enter cells from the outside, it is NAC's ability to easily enter cells that permits cells to create the high concentrations of glutathione they require.

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 produced by the body, so if increased levels of NAC are desired, Andrew's NAC-500 is a simple and affordable way of doing so.
