N-Acetyl-L-cysteine Description:
N-Acetyl-L-cysteine is made from the amino acid cysteine joined to an acetyl group. This nutrient (sometimes abbreviated as N-A-C or NAC) is a strong antioxidant.
N-Acetyl-L-cysteine donates the amino acid cysteine to help form the antioxidant glutathione, a powerful natural antioxidant normally found in the body.
N-Acetyl-L-cysteine Effects:
N-acetylcysteine is an excellent source of sulfhydryl groups and is converted in the body into metabolites capable of stimulating glutathione synthesis, promoting detoxification, and acting directly as a free radical scavenger.
Administration has historically been as a mucolytic [mucus dissolving] agent in a variety of respiratory illnesses;
however, N-Acetyl-L-cysteine appears to also have beneficial effects in conditions characterized by decreased glutathione or oxidative stress, such as HIV infection, cancer, heart disease, and cigarette smoking.
