What is NAC N-Acetyl-L-Cysteine?
N-acetyl-l-cysteine, also known as N-acetylcysteine or Acetylcysteine (NAC), is a pharmaceutical drug and nutritional supplement used primarily as a mucolytic agent and in the management of paracetamol (acetaminophen) overdose. Other uses include sulfate repletion in conditions, such as autism, where cysteine and related sulfur amino acids may be depleted.
N-acetyl-l-cysteine is a derivative of cysteine where an acetyl group is attached to the nitrogen atom. This compound is sold as a dietary supplement commonly claiming antioxidant and liver protecting effects. It is used as a cough medicine because it breaks disulfide bonds in mucus and liquefies it, making it easier to cough up. It is also this action of breaking disulfide bonds that makes it useful in thinning the abnormally thick mucus in cystic and pulmonary fibrosis patients.

Antioxidant effect: N-acetyl-L-cysteine has antioxidant effect, which can help scavenge free radicals and reduce the damage of oxidative stress to the body. It can increase the production of glutathione by providing glutathione precursors, thus improving the antioxidant capacity of cells.
Detoxification: NAC is often used as a detoxifier in medicine. It can combine with some toxic substances, such as acetaminophen overdose, alcohol poisoning or heavy metal poisoning, to help reduce toxicity and protect organs.
Bronchial disease treatment: N-acetyl-L-cysteine is also used in the treatment of bronchial diseases, such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis. It can help thin and clear mucus, reduce inflammation, and improve respiratory function.
Mental health support: NAC has also been studied for use in mental health areas such as depression, anxiety, and obsessive-compulsive disorder. It may work by improving neurotransmitter balance, reducing oxidative stress and inflammatory responses, among other mechanisms.
