N-Acetyl-L-Cysteine by Seeking Health provides 500 mg of N-Acetyl-L-Cysteine (NAC) to support the health of the liver, brain, lungs, and other body tissues.* Supplement NAC may also help support the production of glutathione, one of the body's most important antioxidants.*

NAC may help support and maintain healthy brain and nerve cells. NAC's relation to the body's antioxidant system suggests that it may play a role in protecting against oxidative damage to neurons, the specialized cells found in the nervous system that are vital to maintaining memory and cognitive function. NAC supports antioxidant activity by helping to produce intracellular glutathione, and adequate levels of glutathione are crucial for healthy function of the liver, nerve cells, brain, pancreas, and lungs. NAC is normally present in high amounts in lung and liver tissues. It provides immune and respiratory system support by helping to disrupt disulfide bonds of proteins found in mucus, allowing it to be more easily expelled from the lungs. The antioxidant action of NAC may also help protect the lungs and support the immune system.*
