Take quercetin supplement with bromelain

What to Do

Take quercetin 500-1000mg daily in divided doses, combined with bromelain (pineapple enzyme) to improve absorption. Start several weeks before allergy season begins.

Why It Works

Quercetin is a plant flavonoid that stabilizes mast cells, preventing histamine release. A 2020 RCT found quercetin 500mg/day reduced symptom severity significantly compared to placebo over 8 weeks. It works as a preventive, not a rescue medication — chronic supplementation is needed.

Tips

• Take with fats or combine with bromelain to overcome poor bioavailability
• Interacts with roughly 60 medications including warfarin and aspirin — check with your pharmacist
• Not a substitute for conventional treatment in moderate-to-severe allergies
• Available in many combination allergy supplements
