Phase 3 original market research · August 21, 2026

Senolytic Supplement Database 2026

A source-backed comparison of 21 current fisetin and senolytic products. Phase 3 adds proprietary transparency, value, evidence-match and stack-complexity scores while keeping those scores separate from clinical efficacy.

Fisetin and senolytic product database research

Phase 3 market snapshot

21 products

Current single-ingredient, enhanced-bioavailability and multi-senolytic products in the expanded database.

8–1,500 mg

Verified fisetin per stated serving across 18 entries. Median: 112.5 mg.

10/21 testing disclosures

Entries where the reviewed source explicitly disclosed testing or comparable retailer verification.

Why the scores matter

Transparency Score rewards dose, serving, price, testing, COA and manufacturing disclosure. Fisetin Value Score is a price-density comparison where usable dose and price are both captured. Evidence Match Score asks how cleanly the commercial formula maps to the ingredient being discussed in research. Stack Complexity describes formula breadth. None of these scores predicts health outcomes.

What the expanded sample shows

The market is not standardized. Some products sell 100 mg conventional capsules; others sell 500 mg high-dose capsules; enhanced-bioavailability products may use much smaller nominal amounts; and multi-senolytic stacks can contain more than a gram of fisetin inside a short-duration protocol. Comparing milligrams alone is therefore a crude buying method.

Price density also varies sharply. Phase 3 calculates it only when the database contains both a current captured price and a verified fisetin amount. Multi-active formulas and entries with missing dose fields are deliberately left unscored rather than forced into a fake ranking.

Why the database exists

Narrative product reviews are difficult to audit. The database turns product comparisons into explicit fields such as dose, price, serving size, testing, COA visibility, formulation, and stack structure.

What is included

The current database covers focused Fisetin products, liposomal and enhanced-bioavailability products, higher-dose options, and broader senolytic or longevity stacks.

Why missing data stay missing

When a current source does not expose a dose, price, test document, or certification, the database records that gap rather than filling it from old snippets or assumptions.

Transparency Score

Transparency rewards clear dose, testing, COA availability, serving structure, ingredient source, price visibility, and manufacturing disclosure. It measures auditability rather than efficacy.

Fisetin Value Score

Value Score applies only where enough verified dose and price data exist to support a normalized comparison. It does not imply that the cheapest milligram is the best product.

Evidence Match

Evidence Match asks how closely a commercial product maps to the ingredient discussed in the literature. Focused formulas are often easier to evaluate than complicated blends.

Stack Complexity

Complexity describes how many active components a formula contains. More complexity means more questions about dose sufficiency, overlap, interactions, and finished-formula evidence.

How the database will evolve

Future updates can add more brands, historical price tracking, standardized testing fields, subscriptions, refund policies, and finished-formula human-study data.

Update trigger 1

For Senolytic Supplement Database 2026, the conclusion should remain open to revision. New human studies, formula changes, updated COAs, price changes, and newly disclosed testing can all alter the commercial recommendation. The useful goal is not to create a permanent winner, but to make the comparison transparent enough that readers can see why the conclusion was reached and what evidence would change it.
