N-acetylcysteine is a derivative of the amino acid L-cysteine, and a precursor of the amino acid, Glutathione, a powerful antioxidant.
NAC is the acetylated form of L-cysteine rendering it more stable and absorbable than L-cysteine.
Antioxidants help the body get rid of harmful compounds (free radicals) that damage cell membranes and DNA, and researchers link free radicals to aging, heart disease and cancer.
NAC promotes healthier cell production and energy transfer, improves stamina and reduce recovery time. It supports normal immune system functioning and by restoring glutathione levels, protects the liver, especially from acetaminophen poisoning (Tylenol), hepatitis or HIV.
It may have a direct mineral chelating effect and proves to be beneficial in the treatment of lead poisoning.
NAC is useful as a mucolytic agent, (mucous-thinner) for the treatment of chronic bronchitis and other pulmonary diseases, the management of type 2 diabetis and insulin sensitivity. Multiple studies also demonstrated positive effects from long-term NAC supplementation, on psychiatric conditions.
How it works:
N-Acetyl-L-Cysteine is produced from the amino acid Cysteine, joined to an acetyl group and is rapidly absorbed following an oral dose.
As an excellent source of sulfhydryl groups, it is primarily used as mucolytic agent in acetaminophen poisoning and pulmonary diseases.
NAC is capable of stimulating gluthathione synthesis, a powerful antioxidant promoting detoxification, and have been shown to benefit conditions associated with oxidative stress or inflammation.
NAC is not naturally found in food sources, but cysteine is present in most high protein foods:
