What This Page Explains
This page explains the science of senolytics — compounds that selectively clear zombie cells — including fisetin, quercetin, and spermidine.
Could Senolytics Help You?
Discover if your symptoms align with senescent cell accumulation.
Detailed Evidence
Mayo Clinic human trials are ongoing. Observational data shows people with higher intake of senolytic-rich foods have better health outcomes. ReCellence™ contains fisetin, quercetin, and spermidine at researched doses.
Evidence Hierarchy
Systematic Reviews & Meta-Analyses
Multiple high-quality trials combined
Randomized Controlled Trials (RCTs)
Gold standard for treatment efficacy
Observational Studies
Can show associations, not causation
Case Reports & Expert Opinion
Hypothesis-generating only
Preclinical (Lab/Animal) Studies
Should NOT be extrapolated to humans
Get Clinically-Studied Ingredients
ReCellence™ combines fisetin, quercetin, spermidine, and other senolytic-supporting compounds.
Study Quality Indicators
Higher Quality Indicators
- Large sample size (hundreds to thousands)
- Randomized and blinded design
- Placebo-controlled comparison
- Published in peer-reviewed journals
- Replicated in multiple studies
- Registered trial protocol before starting
Lower Quality Indicators
- Small sample size (under 100)
- No control group or blinding
- Manufacturer-funded with conflicts
- Only animal/cell studies
- Never replicated
- Published in predatory journals
Important Limitations
- • Supplement research often has methodological limitations
- • Results from one study may not generalize to all people
- • Marketing claims often exceed what research supports
- • Absence of evidence is not evidence of absence
- • Individual response to supplements varies widely
Quick Answers
What are senolytics?
Senolytics are compounds that selectively induce death in senescent (zombie) cells while leaving healthy cells unharmed. The term combines "senescent" + "lytic" (to destroy).
What is fisetin?
Fisetin is a natural flavonoid found in strawberries and cucumbers. Mayo Clinic research identified it as the most effective natural senolytic compound discovered to date.
What is autophagy?
Autophagy is your cells' built-in self-cleaning system that identifies and recycles damaged components. It won the 2016 Nobel Prize in Physiology or Medicine.
Does spermidine help clear zombie cells?
Spermidine activates autophagy, your body's natural cell-cleaning process. This helps prevent damaged components from accumulating and triggering senescence.
