Pterostilbene: A Potent Antioxidant for Longevity and Health
Pterostilbene is a naturally occurring compound found in blueberries, grapes, and certain types of wood. Structurally similar to resveratrol, it belongs to the stilbene family of polyphenols and is gaining attention for its superior bioavailability and wide-ranging health benefits.
What Makes Pterostilbene Unique?
Compared to resveratrol, pterostilbene has:
4x greater absorption in the body
A longer half-life, meaning it stays active longer
Enhanced lipophilicity, allowing it to cross cell membranes and the blood-brain barrier more effectively
Key Health Benefits
Research suggests pterostilbene may:
Protect brain cells and improve memory and cognition
Reduce inflammation
Support cardiovascular health by lowering blood pressure and improving cholesterol profiles
Act as an anti-cancer agent, inducing apoptosis and inhibiting tumor growth in various cancers
Improve insulin sensitivity and help regulate blood sugar levels
Mechanism of Action
Pterostilbene activates key cellular pathways such as:
Nrf2, which boosts antioxidant defenses
AMPK/SIRT1, involved in energy metabolism and mitochondrial health
TGF-β1/Smad, relevant in fibrotic disease modulation6
How to Take It
- Found naturally in blueberries (though in small amounts)
- Available as a dietary supplement, often in doses ranging from 50–250 mg/day
- Best taken with food or healthy fats to improve absorption
