Acetylcysteine or N-Acetylcysteine (NAC) is a supplement that is not naturally occuring in food sources. It’s an altered form of the amino acid cycsteine. When NAC is consumed it is metabolized into it’s bioactive form of L-cysteine. L-cysteine serves as a precursor to the powerful antioxidant glutathione..

Healing Properties

  • Antioxidant
    • ‘N-acetylcysteine (NAC) directly scavenges free radicals.’
    • ‘N-acetylcysteine is also a precursor for glutathione synthesis.’
  • Blood Flow (Improves)
    • ‘Promotes increased blood flow through nitric oxide-mediated pathways.’
  • Kidney Health
    • ‘Has been shown to help maintain proper kidney function through antioxidant effects.’
  • Liver Health’
    • ‘Glutathione mediated mechanisms are among the most important defense mechanisms of the liver; N-acetylcysteine (NAC) provides cysteine for glutathione defense mechanisms.’
    • ‘It helps improve serum levels of aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and bilirubin.’
  • ‘Nephroprotective’
    • ‘Has been shown to help prevent or treat some forms of acute kidney failure.’

Disease & Symptom Treatment

  • ‘Glutathione Deficiency’
    • ‘N-acetylcysteine is a precursor for glutathione synthesis.’
    • ‘N-acetylcysteine (NAC) provides cysteine for glutathione defense mechanisms.’
  • ‘Nephropathy’
    • ‘Acetylcysteine has shown potential for benefit as a nephroprotective agent’
