Foster Regal N-Acetylcysteine (NAC) 600 mg 60 Capsules

Antioxidant Neutralizes Cell Damaging Free Radicals

Acetylcysteine is a derivative of cysteine; an acetyl group that 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.
It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.
