Here is the science, and the senolytic supplements you can actually buy — graded on the research.* ## What senolytics do As we age, some cells stop dividing but refuse to die — “senescent” cells that secrete inflammatory signals (the SASP) and accelerate tissue aging. **Senolytics** are compounds that selectively push these cells to clear. The most studied natural senolytics are the flavonoids [fisetin](https://magellanlongevity.com/p/101.md) and [quercetin](https://magellanlongevity.com/p/105.md), both under active human investigation. See the broader [senolytics & senescence research](https://magellanlongevity.com/longevity-research-map.html). ## Evidence-graded senolytic supplements Linked to their mechanisms and PubMed studies. | Product | Evidence grade | Citations | Typical price | Why it is on this list | | --- | --- | --- | --- | --- | | [Fisetin Senolytic Capsules](https://magellanlongevity.com/p/101.md) | Emerging evidence | 25 | $36.45 | Because senescent cells accumulate with age and contribute to frailty, vascular dysfunction, inflammation, and… | | [Quercetin Capsules](https://magellanlongevity.com/p/105.md) | Moderate evidence | 25 | $21.42 | Meta-analyses of randomized trials indicate quercetin produces a small blood-pressure reduction—on the order of 2–3… | ## Evidence detail ### Fisetin Senolytic Capsules - **Evidence grade:** Emerging evidence - **What the grade does not say:** Nearly all senolytic evidence is preclinical, and the 2018 mouse lifespan finding was not replicated by the NIA Interventions Testing Program in 2024. Small human RCTs show anti-inflammatory effects (for example 100 mg/day for 7 weeks in cancer patients), but no published trial has shown senescent-cell clearance or aging benefits in healthy people. Anti-aging use remains speculative pending larger trials. ### Quercetin Capsules - **Evidence grade:** Moderate evidence - **Dose used in studies:** ≥500 mg/day (blood-pressure effects appear mainly at 500 mg/day and above) - **What the grade does not say:** Meta-analyses show a small (~2–3 mmHg) blood-pressure reduction, mostly in people with hypertension; lipids and glucose show no meaningful effect, and oral bioavailability is poor. The headline 'senolytic' claims come from the dasatinib+quercetin drug combination in early trials — the biggest 2024 trial was negative overall — not from quercetin capsules alone. ## Frequently asked questions ### What are senolytics? Senolytics are compounds that selectively clear senescent “zombie” cells — cells that have stopped dividing but secrete inflammatory signals that drive aging. ### Is fisetin a senolytic? Fisetin is the most-studied natural senolytic flavonoid, found in strawberries, and is under active clinical investigation for clearing senescent cells. ### Do senolytics work in humans? Early human trials are underway and mechanistic and animal data are strong, but large long-term human outcome trials are still limited. Each product page links to the current evidence. ### How are senolytics usually taken? Many protocols use intermittent (“hit-and-run”) dosing rather than daily use. Discuss any senolytic regimen with your physician. ## The research behind these picks Primary peer-reviewed sources for the products above.
