How Fisetin Reverses Frailty: The 2025 Senolytic Trial

Oral intermittent supplementation with the natural flavonoid fisetin mitigates age-associated increases in frailty and declines in grip strength. A 2025 study by Murray et al. evaluated fisetin against two well-established senolytic approaches: genetic-based clearance of p16+ senescent cells and the synthetic pharmacological senolytic ABT-263. The results provide a striking signal for longevity science. Fisetin improved frailty and grip strength in old mice to a similar extent as both the genetic clearance model and the synthetic drug ABT-263. Here is what the trial data actually showed: - Old mice were given fisetin at 50 mg/kg/day on an intermittent dosing schedule of 1 week on, 2 weeks off, and 1 week on. - The fisetin group demonstrated a 15% lower frailty index score compared to the vehicle-treated old mice. - The fisetin group also exhibited a 14% higher grip strength compared to the vehicle-treated old mice. - Transcriptomic analysis of the quadriceps muscle showed that fisetin favorably altered cellular senescence-related gene expression. - Specifically, fisetin ameliorated the age-related increase in Cdkn1a (the gene encoding p21) by approximately 46%. - Fisetin also lowered the expression of Ddit4, a DNA damage-inducible transcript that inhibits the mTORC1 pathway. - Fisetin treatment had no effects on physical function in young mice. As a physician, seeing a food-derived flavonoid match the physical functional improvements of targeted synthetic senolytics—without disrupting basal physiological processes—is a critical benchmark for cellular bioenergetics and healthy aging protocols.
