NOW Foods NAC 1,000 mg Tablets in Pakistan NOW Foods NAC (N-acetylcysteine) 1,000 mg Tablets deliver a pharmaceutical-grade dose of the acetylated derivative of the amino acid L-cysteine, engineered to overcome the pharmacokinetic limitations of native cysteine. This formulation provides 1,000 mg of pure N-acetylcysteine per tablet—a therapeutic dosage established in both clinical medicine and nutritional biochemistry for its triple-action mechanism as a glutathione precursor, mucolytic agent, and redox modulator. NAC's molecular architecture features an acetyl group protecting the reactive thiol (-SH) during gastrointestinal transit, enabling efficient systemic delivery where deacetylation liberates bioactive cysteine. In addition to its detoxifying properties, NAC is known for its ability to replenish glutathione levels in the body, a vital antioxidant that helps combat oxidative stress. This makes NOW Foods NAC an excellent choice for individuals seeking to boost their antioxidant defenses and maintain cellular health. With 1,000 mg per tablet, you can easily incorporate this supplement into your routine for maximum benefits. NOW Foods is committed to quality, ensuring that each tablet is manufactured to the highest standards. With a focus on purity and potency, you can trust that you are getting a reliable product. Elevate your health today with NOW Foods NAC 1,000 mg Tablets and experience the difference in your well-being.

The tablet employs pharmaceutical excipients while maintaining NOW Foods' standards of purity, free from common allergens and artificial additives. NAC operates through three primary biochemical pathways: 1) Direct cysteine donation for glutathione synthesis (rate-limiting substrate), 2) Thiol-mediated disulfide bond reduction in mucoproteins, and 3) Scavenging of reactive oxygen and nitrogen species via its free thiol group. This multi-mechanistic profile makes 1,000 mg NAC particularly relevant for conditions involving glutathione depletion (toxin exposure, chronic disease), respiratory mucus viscosity (COPD, bronchiectasis), compulsive behaviors (trichotillomania, skin picking), and neuropsychiatric disorders where glutamate modulation and oxidative stress intersect.

BENEFITS:

Glutathione Synthesis & Redox Homeostasis

Rate-Limiting Substrate Provision:

• γ-Glutamylcysteine Synthetase (GCS): NAC provides cysteine, overcoming feedback inhibition by glutathione (Ki ~2.3 mM)
• Transport: NAC crosses membranes via sodium-dependent transporters, then is deacetylated intracellularly
• GSH Synthesis Rate: Increases hepatic GSH 50-100% within 2 hours (dose-dependent)
• Tissue Distribution: Preferentially increases GSH in mitochondria (30-40%) > cytosol > extracellular

Glutathione-Dependent Detoxification:

• Phase II Conjugation: GSH-S-transferase substrates (electrophiles, heavy metals, xenobiotics)
• Peroxidase Systems: GSH peroxidase (GPx) reduces H₂O₂ and lipid hydroperoxides
• Radical Scavenging: Direct reaction with •OH, O₂•⁻, ONOO⁻ (k ~10⁹-10¹⁰ M⁻¹s⁻¹)
• Redox Cycling: Regenerates ascorbate and α-tocopherol from oxidized forms

Mitochondrial Protection:

• Complex I-IV Preservation: Maintains electron transport chain integrity under oxidative stress
• MPTP Inhibition: Prevents mitochondrial permeability transition pore opening
• Cardiolipin Protection: Prevents peroxidation of inner mitochondrial membrane phospholipid
• Mitophagy Regulation: Modulates the PINK1/Parkin pathway for damaged organelle clearance
