Resveratrol
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.

Mechanism of Action
Resveratrol (3,5,4′-trihydroxystilbene) is a polyphenolic compound produced by plants under stress conditions. Its primary longevity-related mechanisms include:
- SIRT1 activation: Resveratrol acts as a SIRT1-activating compound (STAC), allosterically activating SIRT1 deacetylase activity. SIRT1 requires NAD+ as a co-substrate, which is why co-supplementation with NMN produces synergistic effects.
- AMPK activation: Resveratrol activates AMPK (AMP-activated protein kinase), the master metabolic sensor, mimicking some aspects of caloric restriction
- Anti-inflammatory: Inhibits NF-κB signalling, reducing inflammatory cytokine production
- Antioxidant: Scavenges reactive oxygen species via its polyphenol hydroxyl groups
Bioavailability Challenge
Standard resveratrol has notoriously poor oral bioavailability (~1%) due to rapid hepatic conjugation. Key strategies to improve absorption:
- Take with fat: Co-ingestion with a fat-containing meal increases bioavailability 5-fold
- Micronised formulations: Particle reduction increases surface area and absorption rate
- Liposomal delivery: Enhanced bioavailability in preliminary studies
- Trans- vs cis-isomer: trans-resveratrol is the biologically active form — verify this in product COAs
Clinical Evidence Summary
A 2012 meta-analysis of 11 RCTs found significant improvements in fasting glucose, insulin, and blood pressure in type 2 diabetic patients.
[2] A 2020 systematic review noted benefits in cardiovascular biomarkers, though acknowledged the bioavailability challenge as a limiting factor across studies.

Stacking Interactions
How Resveratrol interacts with other compounds
Classic Sinclair protocol: take together in the morning with a fat-containing meal. Fat improves resveratrol bioavailability significantly.
Both are poorly bioavailable without fat. Take together at meals.
No significant direct interaction. Can be taken together without concern.
