Frequently Asked Questions
What is quercetin?
Quercetin is a powerful plant-based antioxidant, known as a flavonoid, found in foods like onions, apples, and capers. It is widely used to support a healthy immune response, reduce inflammation, and manage seasonal allergy symptoms.
How much quercetin is safe to take daily?
A typical daily dose of quercetin is 500-1000 mg, often split into two servings. While generally safe, high doses may cause headaches or stomach upset. It's best to consult a healthcare professional, especially if you have kidney issues or take other medications.
How does quercetin help with allergies?
Quercetin acts as a natural antihistamine by stabilizing mast cells, which prevents them from releasing histamine—the compound that causes allergy symptoms like sneezing and itching. This helps calm the body's overactive response to allergens like pollen.
