Quercetin
A plant compound studied with dasatinib as part of one of the best-known experimental senolytic combinations.
Quercetin is a naturally occurring plant compound found in foods such as onions, apples, and berries. In longevity research it is often mentioned because it has been studied with the cancer drug dasatinib in the senolytic combination known as D+Q.
Its presence in foods does not mean normal diet levels produce the same effects studied in research trials. The senolytic discussion is about a specific experimental context, not a simple longevity shortcut.
Worth Knowing
Quercetin is often described as a flavonoid, which is a broader family of plant compounds. In senolytic research, the important distinction is not the nutrition label alone but the dose, context, and pairing with dasatinib.
