What is the recommended dosage for N-Acetylcysteine?

General: 600-1,200 mg/day; Respiratory Support: 600 mg 2-3x/day

What are the side effects of N-Acetylcysteine?

Potential side effects include: Gastrointestinal discomfort (nausea, diarrhea), Unpleasant sulfur taste/smell, Headache, Rare: bronchospasm (in asthma patients, inhaled form).

What is NAC and how does it support the immune system?

N-acetylcysteine (NAC) is a precursor to glutathione, the body's primary intracellular antioxidant. Studies have examined NAC for its potential to support respiratory health, reduce oxidative stress, and maintain immune cell function during illness.

What dosage of NAC has been studied for immune support?

Clinical trials have used NAC at doses of 600–1,800 mg per day, typically divided into two or three doses. For respiratory health outcomes, 600 mg twice daily is a commonly studied regimen over periods of 3 to 6 months.

What are the potential side effects of NAC?

Common side effects include nausea, vomiting, diarrhea, and an unpleasant sulfur taste. NAC may interact with nitroglycerin and certain blood pressure medications. Individuals with asthma should use caution, as inhaled NAC can trigger bronchospasm.

About

N-Acetylcysteine (NAC) is a direct precursor of glutathione, the body's master antioxidant. It replenishes intracellular glutathione to protect immune cells from oxidative damage, exhibits mucolytic activity to reduce respiratory mucus, and may modulate NF-kB signaling and inflammatory cascades.

How It Works

Direct precursor of glutathione; replenishes intracellular glutathione to protect immune cells from oxidative damage; exhibits mucolytic activity; may modulate NF-kB signaling and inflammatory cascades.
