Quercetin
Quercetin is a flavonoid. You find it in onions, apples, capers, and berries. It has antioxidant and anti-inflammatory activity. It is being studied as a senolytic. (A senolytic kills the worn-out 'zombie' cells that build up in you.) But on its own, that senolytic activity is inconsistent in human cell models. The version actually tested in early human trials is quercetin plus dasatinib (D+Q). As a standalone supplement, it has shown small, inconsistent blood-pressure effects, mainly in people with hypertension. And its absorption is low. The human anti-aging evidence is preliminary.
