N-Acetyl-L-Cysteine, or N-A-C, is an acetylated form of the amino acid cysteine. Cysteine is the most important precursor to glutathione (GSH), the most critical antioxidant produced in the body. Glutathione helps chelate toxins and heavy metals from the body. N-A-C is approved as a drug in some European jurisdictions for use in preventing liver damage from acetaminophen overdose. It has been used for over 30 years for respiratory health, providing some relief to those suffering from chronic respiratory conditions such as the annoying post-nasal drip, sinusitis, chronic bronchitis, the congenital disease cystic fibrosis, and even life-threatening conditions such as COPD. N-A-C also promotes cardiovascular health due to its unique ability to inhibit levels of a specific lipoprotein called Lp(a), a marker of heart disease.
Acetylated cysteine is better absorbed than regular cysteine. AOR’s N-A-C is an excellent choice for those looking for a single supplement to promote overall health including cellular protection and cardiovascular health. People suffering from chronic respiratory conditions may also benefit from regular use of N-A-C.
