Resveratrol vs Fisetin

Side-by-side comparison of evidence grade, dosage, safety, and stacking compatibility.

Combined: Synergistic ✦Both taken with fat for bioavailability. Can be co-administered on pulse dosing

Overview

A polyphenolic stilbenoid found in red wine and grape skins that activates SIRT1 and AMPK pathways. Requires NAD+ co-factors for maximal sirtuin activation, making it synergistic with NMN.

Summary

A flavonoid found in strawberries with the most potent senolytic activity among all tested compounds. Selectively eliminates senescent cells that accumulate with age and drive systemic inflammation — the SASP effect.
