It cleared up life long issues within a couple days, but it came with a few strange side effects. Here, the effects of NAC on virus replication, virus-induced pro-inflammatory responses and virus-induced apoptosis were investigated in H5N1-infected lung epithelial (A549) cells. Cysteine is an amino acid that is important for regenerating another vital antioxidant, glutathione. [7-9] These effects were originally attributed to the ability of NAC to reduce mucus viscosity and facilitate expectoration. A study published in Chest showed 1-year treatment with high-dose NAC resulted in significantly improved small airways function and decreased exacerbation frequency in patients with stable COPD. According to new research at the University of Virginia Health System, N-acetylcysteine (NAC), an anti-oxidant commonly used in nutritional and body-building supplements, can form a red blood cell NAC is a hydrophilic precursor of cysteine and GSH (24); Trolox is a soluble analog of vitamin E, a lipophilic peroxyl radical scavenger (25). NAC has been the subject of several studies on a number of viruses, going back decades. Those treated with NAC had significantly fewer exacerbations (~1. "NAC is a robust treatment for COPD that reduces phlegm and cough, thins mucus NAC works as anti-mucolytic to improve gas exchange in the lungs, as well as keep blood from coagulation and from developing thrombosis.
