N-acetylcysteine (NAC) decongests the lungs, chelates heavy metals and chemicals, supports the immune system, and increases glutathione levels.
N-Acetylcysteine (NAC) is an acetylated form of the amino acid cysteine which is more efficiently absorbed. It is also an antioxidant that is helpful at fighting viruses. It is commonly used to help break down mucus and to protect from acetaminophen toxicity. In addition, it helps the body to synthesize the antioxidant glutathione. NAC helps to reduce plasma-cell adhesion in type 2 diabetes patients. While NAC does reduce the amount of damage caused to the lungs by cigarette smoking, it does not completely protect them from damage. NAC is effective in the treatment of lung damage caused by inhalation of airborne chemicals. NAC is also used as a liver protectant and appears effective in reducing complications related to liver transplants
