Senolytic and Cellular Cleanup Protocol.
An advanced longevity stack built around senolytic and autophagy-supporting compounds that aim to clear senescent cells and recycle damaged cellular components. It pairs evidence-backed flavonoids and a gut metabolite with foundational mitochondrial and antioxidant support.
The senolytic and cellular cleanup protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Senolytic and Cellular Cleanup Protocol is an advanced stack of 6 supplements aimed at longevity: Fisetin, Quercetin, Spermidine, Urolithin A, Coenzyme Q10 Ubiquinol, and Nicotinamide Riboside. 4 are core and the rest are optional add-ons, at roughly $60-110/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the senolytic and cellular cleanup protocol.
Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.
| Supplement | Dose | Timing | Role | Evidence |
|---|---|---|---|---|
| Fisetin | 100-500 mg/day, often cycled 2 consecutive days per week or month | With a fat-containing meal to aid absorption | Core | Emerging |
| Quercetin | 500-1000 mg/day (commonly paired in senolytic dosing schedules) | With a meal containing fat; can be cycled alongside Fisetin | Core | Emerging |
| Spermidine | 1-6 mg/day | Once daily, with or without food | Core | Moderate |
| Urolithin A | 500-1000 mg/day | Once daily with a meal | Core | Moderate |
| Coenzyme Q10 Ubiquinol | 100-200 mg/day | With a fat-containing meal | Optional | Moderate |
| Nicotinamide Riboside | 300-500 mg/day | In the morning, with or without food | Optional | Moderate |
Fisetin is among the most potent natural senolytic flavonoids in screening studies, selectively reducing senescent cell burden and extending healthspan in aged mice, which is why it anchors this cellular-cleanup stack.
Quercetin is the classic senolytic partner studied in the dasatinib-plus-quercetin paradigm, and as a flavonoid it complements Fisetin in targeting senescent-cell survival pathways while providing antioxidant support.
Spermidine is a well-characterized inducer of autophagy, the cellular recycling process central to cleaning up damaged proteins and organelles, and higher dietary intake is associated with lower mortality in human cohorts.
Urolithin A stimulates mitophagy, the selective clearance of damaged mitochondria, and human trials show improvements in mitochondrial gene expression and muscle endurance, making it a targeted complement to whole-cell autophagy support.
Ubiquinol supports mitochondrial electron transport and acts as a lipid-phase antioxidant, providing baseline mitochondrial resilience that pairs with the mitophagy turnover driven by Urolithin A.
Nicotinamide Riboside raises NAD+ levels that decline with age and fuel sirtuin- and PARP-dependent repair and autophagy pathways, supporting the energetic and signaling backdrop these cleanup mechanisms depend on.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- Fisetin and Quercetin are complementary senolytic flavonoids that together broaden coverage of senescent-cell survival pathways, while Spermidine and Urolithin A add autophagy and mitophagy to clear the debris left behind.
- Nicotinamide Riboside restores NAD+ that powers the sirtuin and repair signaling underlying autophagy, and Ubiquinol protects the mitochondria that Urolithin A renews, so the energetic-support members reinforce the cleanup members.
