N-Acetylcysteine (NAC) is a high-performance pharmaceutical-grade derivative of the amino acid L-cysteine, widely recognized in veterinary medicine for its critical role in detoxification, respiratory support, and antioxidant defense. By serving as a primary precursor to Glutathione (GSH), NAC provides a powerful biochemical shield that protects livestock and pets from hepatic necrosis, oxidative stress, and chronic pulmonary inflammation.
Our premium NAC is engineered for maximum bioavailability and stability, making it an essential additive for animal health. From mitigating heat stress in poultry to treating acute acetaminophen poisoning in companion animals and combating respiratory infections in swine, N-Acetylcysteine delivers precise therapeutic outcomes that improve survival rates, enhance vaccine efficacy, and optimize overall livestock productivity.

Frequently Asked Questions
NAC replenishes intracellular glutathione (GSH), which neutralizes toxic metabolites like NAPQI in acetaminophen poisoning and binds to heavy metals via its sulfhydryl groups, protecting the liver from necrosis.
NAC breaks the disulfide bonds in mucus glycoproteins, reducing the viscosity of secretions and making it easier for animals to clear their airways during pneumonia or bronchitis.
Yes, it is used as a feed additive (typically 200-500 mg/kg) to reduce oxidative damage and stress during transport or in high-density farming environments.
NAC should not be used concurrently with strong oxidizers (e.g., potassium permanganate) or certain antibiotics like penicillin. It is recommended to administer these treatments at least 2 hours apart.
For poultry, use a concentration of 100-200 mg/L for 3-5 days. Because NAC oxidizes rapidly in water, solutions must be prepared fresh daily for maximum efficacy.
Recent research indicates that NAC can serve as an antiviral adjunct, showing an ability to inhibit PRRSV (Porcine Reproductive and Respiratory Syndrome Virus) replication in vitro.
