Background

What Is Resveratrol?

Resveratrol is a polyphenol found in grape skins, red wine, berries, and peanuts. It gained fame through David Sinclair's research at Harvard, showing it activates sirtuin genes (SIRT1) and extends lifespan in yeast. It became the flagship compound of the longevity movement.

🧬 SIRT1 Activation

Activates the SIRT1 gene, a key regulator of cellular aging. SIRT1 controls mitochondrial function, DNA repair, and stress resistance. Resveratrol directly activates SIRT1, mimicking calorie restriction benefits.

🔥 NF-κB Inhibition

Powerful anti-inflammatory effects through NF-κB inhibition. Reduces TNF-α, IL-6, and other pro-inflammatory cytokines. May be as important as SIRT1 activation.

⚡ AMPK Activation

Activates AMPK (AMP-activated protein kinase) — the cellular energy sensor. Increases glucose uptake, improves insulin sensitivity, boosts mitochondrial biogenesis.

🍷 Red Wine Origin

Found in grape skins (concentration increases with fungal infection — hence red wine). You'd need ~100 glasses for therapeutic dose — supplements are necessary.

Research

What the Research Shows

SIRT1 Activation (In Vitro)
Direct activation confirmed in multiple studies
Confirmed
Lifespan Extension (Yeast)
How it all started — ~70% lifespan increase in yeast
+70%
Lifespan Extension (Mice)
High-fat diet mice — mixed results in different studies
Modest
Human Bioavailability
Poor — rapid metabolism limits effectiveness
Low

Key insight: The "French Paradox" (low heart disease despite high fat diet) was initially attributed to resveratrol in red wine. While the dose connection was overstated, the mechanistic research opened an entire field.

Protocol

Dosing & Bioavailability

💊 Standard Dose
  • • 250-500mg daily (common studies)
  • • Up to 1000-1500mg in some trials
  • • Divide doses for better absorption
🔬 Bioavailability Challenge
  • • Rapid metabolism = low bioavailability
  • • Look for trans-resveratrol (active form)
  • • Liposomal/pterostilbene versions help
  • • Take with fat for better absorption

Tip: Pterostilbene (a resveratrol analog) has 4x bioavailability. Many stacks combine resveratrol + pterostilbene for better effect.

Safety

Side Effects

Generally Well-Tolerated

• GI upset: Nausea, diarrhea at high doses
• Headaches: Occasionally reported
• Drug interactions: May interact with blood thinners (warfarin), NSAIDs
• Pregnancy: Avoid during pregnancy (insufficient data)

Bottom Line

Key Takeaways

✅ What We Know
  • Strong mechanistic SIRT1 activation data
  • NF-κB inhibition = anti-inflammatory
  • 70+ clinical trials completed
  • Generally well-tolerated
  • Part of many longevity stacks
⚠️ What We Don't Know
  • Optimal human dose not clear
  • Bioavailability limits effectiveness
  • Mixed results in human trials
  • Long-term effects not well studied
