NAC, or N-acetylcysteine, contains sulfur and is a derivative of the naturally occurring amino acid L-cysteine. It serves as a precursor to glutathione-a key antioxidant that provides protection against free radicals and toxins in the body.
What is NAC good for?
- Counteracting Acetaminophen poisoning Large doses of acetaminophen, or chronic use at lower dosages, can destroy the liver’s ability to make glutathione, resulting in liver failure and death. NAC restores normal liver levels of glutathione and helps to heal the liver damage caused by acetaminophen.
- Cold and Flu protection According to an Italian study of seniors, NAC supplements can block influenza symptoms.
- Polycystic Ovary Syndrome (PCOS) In a recent study, doctors discovered that moderately high doses of NAC led to improvements in women with PCOS.
