Trans-Resveratrol vs Pterostilbene
SIRT1 activators — methoxy groups change absorption, not certainty
The bottom line
Trans-Resveratrol vs Pterostilbene: which is better?
Resveratrol wins for TNiC SIRT1 stack parity with published NMN pairings. Pterostilbene is experimental swap — only with NAD+ monitoring and physician awareness.
What this is
Head-to-head evidence table: Trans-Resveratrol vs Pterostilbene (compound).
Why it matters
Resveratrol has longer human exposure history and SIRT1 literature. Pterostilbene is more lipophilic with longer half-life in preclinical models — human longevity outcomes for both remain Tier B.
What to do next
