If you’re dealing with nasal polyps, thick mucus, and sinus pressure that just won’t quit, N-Acetylcysteine (NAC) could be your natural secret weapon. NAC is a powerful antioxidant and mucolytic (mucus-thinning agent) that’s backed by research for improving respiratory health.
In this article, you’ll learn how NAC works, how it helps nasal polyps, and how to use it safely as part of a natural sinus relief protocol.
What Is NAC (N-Acetylcysteine)?
NAC is a supplement form of the amino acid cysteine. In the body, it helps produce glutathione, your master antioxidant. It’s commonly used to:
- Break up mucus in the lungs and sinuses
- Detoxify the liver and respiratory tract
- Reduce inflammation in chronic respiratory conditions
It’s widely used in functional medicine to treat bronchitis, sinus infections, asthma, and yes—nasal polyps.
How NAC Helps With Nasal Polyps
1. Thins Mucus and Improves Drainage
NAC breaks down disulfide bonds in mucus, making it thinner and easier to drain from the sinuses. This reduces pressure, stuffiness, and infection risk.
2. Supports Glutathione Production
Glutathione reduces oxidative stress and inflammation in nasal tissue—key factors in polyp formation and persistence.
3. Detoxifies Sinuses and Airways
NAC helps remove environmental toxins, allergens, and biofilm buildup that often trigger or worsen nasal polyps.

Best Dosage and How to Use NAC for Sinus Relief
- Typical dose: 600–1,200 mg daily (in divided doses)
- Take with food to avoid upset stomach
- Look for supplements that combine NAC with quercetin, bromelain, or turmeric for added anti-inflammatory benefits
Important: Always consult your healthcare provider if you’re taking medications (especially nitroglycerin or blood thinners)
Who Benefits Most From NAC?
- People with chronic sinusitis or nasal polyps
- Those prone to frequent sinus infections or postnasal drip
- Anyone seeking to support natural sinus detox and drainage
Real Experience: “NAC Was the Missing Piece”
Daniel, 42 – USA: “I used nasal sprays and rinses for years, but the congestion always came back. When I added NAC, my mucus thinned, and I could finally breathe clearly. My polyp symptoms have improved too.”
Final Thoughts: Mucus Relief Starts From Within
If thick mucus and recurring congestion are weighing you down, NAC offers a powerful, natural solution. It’s safe, research-supported, and even more effective when combined with other anti-inflammatory ingredients.
