How Quercetin and Bromelain Work for Nasal Inflammation

Struggling with chronic sinus congestion, pressure, or nasal polyps? You’re not alone—and two of the most powerful, research-backed natural compounds for nasal inflammation are quercetin and bromelain.

This dynamic duo works together to reduce swelling, block histamine reactions, and promote sinus healing—making them a top choice for anyone trying to shrink nasal polyps or relieve chronic sinus issues naturally.

What Is Quercetin?

Quercetin is a plant-derived flavonoid found in onions, apples, berries, and leafy greens. It has powerful antioxidant, antihistamine, and anti-inflammatory properties.

Quercetin helps nasal inflammation by:

  • Stabilizing mast cells (reducing histamine release)
  • Lowering cytokine levels that drive chronic inflammation
  • Protecting sinus tissue from oxidative stress

It’s especially helpful for people with allergy-induced nasal polyps, chronic sinusitis, or asthma-related congestion.


What Is Bromelain?

Bromelain is a natural enzyme found in pineapple stems. It’s best known for its anti-swelling, anti-inflammatory, and digestive benefits.

Bromelain supports sinus relief by:

  • Breaking down fibrin and mucus that block sinus drainage
  • Improving absorption of other nutrients like quercetin
  • Reducing swelling in nasal tissues and polyps

Why Quercetin + Bromelain Work Better Together

These two supplements complement each other beautifully:

  • Quercetin reduces immune overreaction and inflammation
  • Bromelain reduces tissue swelling and helps quercetin work more efficiently

When taken together, they create a synergistic effect that promotes faster sinus relief and natural nasal polyp reduction.

How to Take Them Safely

  • Quercetin dosage: 500–1,000 mg per day (preferably with meals)
  • Bromelain dosage: 100–200 mg per day (or as part of a combined formula)
  • Look for supplements that combine both for convenience and enhanced absorption

Tip: Always choose quercetin with bromelain or take them together for best results.


Who Should Consider This Combo?

  • People with nasal polyps or chronic sinus inflammation
  • Individuals with seasonal or year-round allergies
  • Those seeking a non-steroidal approach to sinus pressure, mucus, and swelling

Final Thoughts: A Natural Combo That Works

Quercetin and bromelain are a natural, non-invasive option to help calm the inflammation behind nasal polyps and chronic sinus congestion. Used consistently, they can offer real, noticeable relief.
