Natural compounds with documented senolytic or senomorphic (SASP-suppressing) activity represent an accessible, safe approach to cellular aging management without pharmaceutical requirements. The evidence hierarchy (from strongest to weakest) places fisetin and quercetin at the top, followed by spermidine, EGCG, luteolin, pterostilbene, astaxanthin, and curcumin as supporting agents.

Do I need all four tiers of natural senolytics?

Tier 1 (fisetin + quercetin) covers the most important mechanisms with the best evidence. Tier 2 (spermidine) adds autophagy prevention. Tiers 3 and 4 provide marginal additional benefits. Start with Tier 1–2 before considering further additions.

Can food alone provide a complete natural senolytic protocol?

No. Food doses of fisetin and quercetin are 10–100x below senolytic thresholds. Diet can support general health and provide background senolytic-adjacent compounds, but supplements are needed for therapeutic senolytic activity.
