Used as a mucolytic agent to break down thick mucus in respiratory conditions such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis. It helps loosen and clear mucus from the airways, improving breathing and reducing infection risk. Also serves as an antioxidant, protecting cells from oxidative stress by boosting glutathione levels in the body. Due to its ability to cross cell membranes more effectively than N-acetylcysteine, it shows potential in neuroprotective applications, including research in Alzheimer's and Parkinson's diseases. Used in some detoxification protocols, especially for acetaminophen overdose, by replenishing glutathione and preventing liver damage. Investigated for its role in reducing inflammation and supporting mitochondrial function in various degenerative and metabolic conditions.
