Origin & tradition
A common cultivated fruit (Fragaria); valued as a dietary source of vitamin C and polyphenols long before its ellagitannin content was studied for cardiometabolic effects.

Strawberry (Polyphenols) 草莓（多酚）
A polyphenol-rich berry with human-RCT signal for insulin sensitivity and cardiometabolic markers — much of the supporting evidence comes from mixed-berry blends rather than strawberry alone, and no trial tests longevity.

Data definition. Matched records include all indexed medical endpoints for this intervention — not only longevity. Longevity-relevant records are screened separately and cited in the evidence summary below. Counts are matched-record volumes, not de-duplicated trials and not efficacy claims.
Why longevity buyers care
Key active: Ellagitannins & anthocyanins.
Ellagitannins are metabolized by gut bacteria into urolithins and, alongside anthocyanins, are thought to drive strawberry's cardiometabolic effects; RCTs show improved insulin sensitivity and lipid/inflammatory markers in insulin-resistant adults, and mixed-berry (including strawberry) trials show modest cognitive and blood-pressure benefits in older adults — but isolated-strawberry, long-duration human trials are scarce, and no study tests lifespan or longevity endpoints.
Effect summary
Studied health outcomes
Editorial summary — This table is curated by hand from published research consensus, not automatically calculated from our trial database. Grades reflect our interpretation of the literature. Treat as a starting point, not a definitive verdict. See the Evidence panel below for the underlying trial and paper counts sourced directly from ClinicalTrials.gov and PubMed.
| Health outcome | Effect | Magnitude | Grade |
|---|---|---|---|
| Insulin sensitivity (insulin-resistant adults) | Increases | Moderate | B |
| LDL cholesterol / lipid profile | Decreases | Minor | B |
| Cognitive performance (mixed-berry blends, older adults) — Most supporting data comes from mixed-berry beverages, not strawberry alone | Increases | Minor | C |
| Lifespan / longevity in humans | No change | Negligible | D |
Grade: A = robust RCTs · B = several RCTs / meta-analysis · C = limited or mixed RCTs · D = observational or early data
Dosage guidance
How Strawberry (Polyphenols) is typically used
- Typical dose
- ~1 cup fresh (≈150–160 g) daily, or ~25 g/day freeze-dried powder (common RCT dose)
- Form
- whole fruit or freeze-dried powder
- Timing
- daily with meals; insulin-sensitivity effects studied over weeks to months
A food — generally safe at dietary intakes. Effects are modest and most reliably shown alongside a broader healthy diet, not as a standalone intervention. Not a treatment for any disease.
Informational only — not a prescription or personalised medical advice. Consult a qualified clinician before starting any supplement or medication.
