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 Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Quercetin at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
