NAC donates cysteine for glutathione synthesis, a master intracellular antioxidant. It breaks disulfide bonds in mucus, thinning secretions, and protects tissues from oxidative damage. Also modulates inflammatory pathways and detoxifies heavy metals and environmental toxins.
Used for chronic obstructive pulmonary disease (COPD), asthma, bronchitis, liver support (e.g., acetaminophen toxicity), psychiatric disorders (OCD, bipolar), fertility, and protection against heavy metal toxicity.
No traditional use — NAC is a modern nutraceutical developed to enhance glutathione production and detoxification pathways.
Available as capsules, powders, or effervescent tablets. Often combined with selenium, glycine, or vitamin C for synergistic antioxidant support.
Use cautiously in individuals with active peptic ulcers or severe asthma without supervision.
May enhance effects of nitroglycerin and blood pressure-lowering medications. May interfere with some chemotherapy drugs.
