What Fisetin is
A plant flavonoid and leading natural senolytic that clears senescent cells in animal studies and is now in human frailty trials.
Fisetin is a flavonoid found in strawberries and other plants that acts as a senolytic, selectively clearing senescent 'zombie' cells that accumulate with age. Animal results have been striking, extending healthspan in mice, and it is now in human clinical trials for frailty and inflammation in older adults.
Mechanism: Selectively triggers death of senescent cells, reducing the inflammatory signals they release.

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.
