NAC — Vendor Pricing & Purity Guide
Research Overview
NAC (N-Acetyl Cysteine) is a derivative of the amino acid L-cysteine and a precursor to glutathione, the body's most important intracellular antioxidant. It is not a peptide but is widely available through peptide vendors. NAC has been used clinically for over 50 years — it is FDA-approved as Mucomyst for acetaminophen overdose and as a mucolytic agent.
NAC's primary mechanism is replenishing intracellular glutathione levels. Glutathione depletion is implicated in numerous conditions including liver disease, respiratory illness, neurodegeneration, and aging. NAC also directly scavenges free radicals and modulates glutamate neurotransmission.
Key Research Findings
- •FDA-approved for acetaminophen overdose treatment (Mucomyst) for over 50 years
- •Primary precursor for glutathione synthesis — the body's master antioxidant
- •Reduced symptom severity in respiratory infections in clinical meta-analyses
- •Demonstrated benefits for psychiatric conditions including OCD and addiction in clinical trials
- •Modulated glutamate neurotransmission via the cystine-glutamate antiporter
Research Dosage Protocols
NAC is orally bioavailable and available as capsules (600-1200 mg), tablets, and powder. IV NAC is used in hospitals for acetaminophen overdose (140 mg/kg loading dose). It is also available through peptide vendors as bulk powder.
