NAC (N-Acetylcysteine) by Thorne – Glutathione and Antioxidant Support
NAC capsules by Thorne provide N-acetylcysteine, a cysteine source for glutathione support, in a single-active-ingredient formula. Each capsule supplies 500 mg, with the same formula available in 90- and 180-capsule bottles for people seeking focused antioxidant support.
Key NAC (N-Acetylcysteine) Benefits
- Supports glutathione production by supplying cysteine, one of the building blocks your body uses to make this important antioxidant.
- Helps maintain cellular antioxidant defenses that neutralize free radicals generated during normal metabolism and everyday environmental exposure.
- Supports respiratory wellness by helping loosen mucus, complementing the natural clearance processes that keep secretions moving through the respiratory tract.
How NAC (N-Acetylcysteine) Works
NAC supplies cysteine, which the body combines with two other amino acids to make glutathione. This supports glutathione production rather than supplying glutathione directly. Glutathione helps neutralize oxidants inside cells. NAC also helps break the bonds that make mucus thick, supporting its normal movement and clearance.
Key Functional Ingredients Include:
- N-Acetyl-L-Cysteine: Supplies cysteine for glutathione synthesis, helping the body maintain its own antioxidant defenses. Glutathione neutralizes oxidants and supports antioxidant enzymes within cells. NAC also loosens the bonds that hold mucus together, helping maintain normal respiratory clearance alongside its antioxidant role.
NAC (N-Acetylcysteine) Is Formulated For
- People seeking focused support for the body's glutathione-based antioxidant defenses.
- People who prefer a single-active-ingredient NAC formula rather than a multi-ingredient antioxidant blend.
