What Quercetin is
A common dietary flavonoid used as a senolytic, most notably paired with the drug dasatinib in human senescence trials.
Quercetin is a widely consumed plant flavonoid with antioxidant and anti-inflammatory properties that also acts as a senolytic. It is best known in longevity research as the partner to the drug dasatinib in the 'D+Q' combination, which reduced senescent cell burden in early human trials in conditions like diabetic kidney disease.
Mechanism: Helps trigger death of senescent cells, particularly in combination with dasatinib, and reduces inflammatory signaling.
Regulatory history: Sold as a supplement; used in senolytic research
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
