Frequently Asked Questions

  • Yes. Quercetin stabilizes mast cells, preventing them from releasing histamine in response to allergens. Clinical studies show 500-1000mg/day reduces allergy symptoms (sneezing, itching, congestion) comparably to some antihistamine drugs. Start 2-4 weeks before allergy season for preventive benefit.

  • For allergies: 500mg 2x/day starting 2-4 weeks before allergy season. For immune support: 500-1000mg/day. For longevity/senolytic effect: 500mg with dasatinib (under practitioner guidance). Standard quercetin has low bioavailability — choose quercetin phytosome or EMIQ (enzymatically modified isoquercitrin) for 20x better absorption.

  • Yes — quercetin is one of the most studied senolytic compounds (agents that clear senescent 'zombie' cells). In combination with dasatinib, it's been shown to reduce senescent cell burden in human trials. As a standalone supplement at 500-1000mg/day, it has milder senolytic activity but still contributes to healthy aging through reduced inflammation and oxidative stress.
