NAC ​​90 Caps Thorne

NAC 500mg for Cellular Detoxification and Antioxidant Defense – NAC Thorne

Thorne's N-Acetylcysteine provides 500 mg of N-acetyl-L-cysteine per capsule — the direct precursor to intracellular glutathione — which can support hepatic and renal detoxification pathways, respiratory well-being, and overall antioxidant balance. With a composition of only four ingredients (active + three excipients), gluten-free, lactose-free, and soy-free, and certified NSF Certified for Sport®, this supplement embodies Thorne's philosophy of quality and transparency.

Thorne's NAC is an amino acid supplement with 500 mg of N-acetyl-L-cysteine per capsule, designed for those who want to support glutathione production, liver detoxification, respiratory well-being, and immune balance. It may be beneficial for active adults, people with high environmental exposure, athletes, or anyone looking to consistently support the body's antioxidant defenses.

Thorne's NAC contains only N-Acetyl-L-Cysteine (NAC) (500 mg per capsule) as its active ingredient — an acetylated derivative of the amino acid L-cysteine. Acetylation improves the stability and bioavailability of cysteine, making it more effective as a glutathione precursor compared to simple L-cysteine.

Glutathione is a tripeptide (glutamate + cysteine + glycine) naturally produced in all cells of the body, where it functions as the main intracellular antioxidant, a cofactor for detoxification enzymes (glutathione S-transferases), and a regulator of cellular redox balance. Glutathione levels can decrease with age, exposure to environmental toxins, intense physical or emotional stress, and certain liver pathologies. NAC supplementation can be an effective way to replenish the substrate needed for intracellular glutathione synthesis.

In addition to its role as a glutathione precursor, NAC also has mucolytic properties — it can act on the disulfide bonds in mucus glycoproteins, reducing their viscosity and promoting their elimination through the airways. This characteristic makes it an amino acid of interest for those who want to support respiratory health.

The excipients — leucine, silicon dioxide, and hypromellose (vegetable capsule) — are commonly used in pharmaceutical-grade formulations.

To consider

• Intended for adults; consult a healthcare professional if pregnant, breastfeeding, or taking regular medication (especially nitroglycerin, anticoagulants, or blood pressure medication) before starting.
• NAC may have a characteristic sulfur odor — this is normal and inherent to the amino acid's composition.
• At high doses, nausea or gastrointestinal discomfort may occur — start with lower doses and adjust gradually.
