N-Acetylcysteine (NAC) is a compound with various health benefits. Firstly, it acts as a potent antioxidant, helping to combat oxidative stress and protecting cells from damage caused by free radicals. This antioxidant role is key to maintaining cellular health and preventing premature aging. Additionally, NAC has been shown to be beneficial for lung health. It is sometimes used as a supplement in the treatment of chronic respiratory diseases such as chronic bronchitis and cystic fibrosis. Its ability to break down and loosen mucus can facilitate breathing and improve lung function in certain conditions. Another notable aspect of NAC is its involvement in liver detoxification. It helps increase the synthesis of glutathione, an essential substance for the detoxification process in the liver. This function contributes to eliminating toxins and unwanted substances from the body, thus promoting health.
