Structure: Fisetin, PubChem CID 5281614

Food or supplementMeasured in people, not heightBy mouthNutrient

A plant compound from fruit, sold both as a sirtuin booster and as something that clears out worn-out cells.

A flavonol found in strawberries and other fruit, sold as a supplement, with a dual reputation: a sirtuin activator and a senolytic, meaning a compound that kills worn-out cells rather than repairing them.

Risks. A supplement, not an approved medicine. Clearing out old cells is not obviously a good idea in a skeleton that is still growing.
