N-acetyl-cysteine

A glutathione precursor strengthening cellular antioxidant defenses.

Definition

A modified form of the amino acid cysteine acting as a precursor to glutathione, the body's master antioxidant.

How it works

N-Acetyl Cysteine (NAC) is a cysteine derivative that easily crosses cell membranes to provide the necessary substrate for glutathione synthesis. Glutathione is the primary antioxidant produced by the body and performs critical detoxification functions. NAC also directly contributes to free radical neutralization and may aid in breaking down biofilms.

Role

Boosts endogenous glutathione production and strengthens cellular antioxidant defenses.

Examples

  • Eggs
  • Garlic
  • Onions
  • Broccoli
  • Chicken

Recommendations

Include sulfur-rich food sources like garlic and crucifers in your diet. NAC supplements are generally used at 600-1200 mg daily, ideally in two doses. Wait at least 2 hours between NAC and mineral intake to avoid interactions.

Key takeaway

N-Acetyl Cysteine bolsters the body's natural antioxidant system by boosting glutathione production.
