Quercetin
PolyphenolsKey Benefits
How It Works
Quercetin inhibits senescent cell survival pathways (when combined with dasatinib in research, or fisetin). It stabilises mast cells reducing histamine release, inhibits inflammatory enzymes (COX, LOX), and has direct antiviral activity by inhibiting viral replication machinery.
Dosage & Timing
Recommended Dosage
500-1,000 mg daily
Best Time to Take
With fat-containing meals for absorption. Phytosome form improves bioavailability.

Generally safe. Rare headaches and GI discomfort. High doses may affect thyroid and kidney function.
Drug Interactions
Interacts with antibiotics (quinolones), cyclosporine, and blood thinners. May affect drug metabolism via CYP enzymes.
What Does The Research Say?
Emerging senolytic research is exciting (clearing zombie cells). Well-established antihistamine and anti-inflammatory effects. COVID-19 research showed potential antiviral benefits. Bioavailability is low; take with vitamin C or use phytosome form.
