Pterostilbene
Pteroresveratrol
Pterostilbene (trans-3,5-dimethoxy-4'-hydroxystilbene) is a methylated analog of resveratrol found primarily in blueberries, grapes, and the Indian Kino tree (Pterocarpus marsupium - hence the name 'pterostilbene'). The two methoxy groups (-OCH3) replacing two of resveratrol's hydroxyl groups give pterostilbene dramatically improved oral bioavailability (~80% vs resveratrol's ~1%) and a much longer plasma half-life (~105 minutes vs resveratrol's ~14 minutes free form). Both compounds activate similar pathways (SIRT1, AMPK, autophagy) but pterostilbene's superior pharmacokinetics make it the more pharmacologically active stilbene at typical supplement doses.,Pterostilbene gained mainstream attention as the resveratrol analog used in Elysium Health's 'Basis' product (alongside nicotinamide riboside) and in numerous longevity-focused formulations. Clinical trials have demonstrated benefits on lipid markers, blood pressure, oxidative stress, and cognitive function. The University of Mississippi Pharmacology department has published extensively on pterostilbene's enhanced potency and bioavailability compared to resveratrol, showing that on a milligram-for-milligram basis, pterostilbene typically produces equivalent or stronger biological effects.,Beyond longevity research, pterostilbene has been studied for cardiovascular protection (cholesterol lowering at 125mg/day in human RCTs), cognitive enhancement (memory and processing speed in older adults), anti-cancer chemoprevention (preclinical), insulin sensitivity, and antioxidant effects. The methylation pattern that gives it bioavailability advantages also reduces phytoestrogen activity compared to resveratrol, making it potentially more suitable for hormone-sensitive populations. Standard supplement doses range from 50-250mg/day, often paired with NAD+ precursors for synergistic longevity protocols.
Take with food (preferably containing some fat). Pairs naturally with NR/NMN as the substrate-activator combination. 50-250mg range covers most clinical use cases. Higher pharmacokinetic stability than resveratrol means once-daily dosing is sufficient for most purposes.

How it works
Pterostilbene shares resveratrol's primary mechanisms - SIRT1 activation (debated), AMPK activation (robust), and autophagy induction - but with substantially better in vivo activity due to superior pharmacokinetics. The two methoxy groups protect pterostilbene from the rapid sulfation/glucuronidation that limits resveratrol, resulting in 80% oral bioavailability vs 1% for resveratrol and tissue concentrations 100-300x higher per equivalent dose.,AMPK activation is dose-dependent and reproducible at physiologically achievable concentrations (low micromolar). Downstream effects include PGC-1alpha activation (mitochondrial biogenesis), mTOR inhibition (autophagy induction), reduced lipogenesis (lower hepatic triglyceride and LDL synthesis), and improved fatty acid oxidation. The metabolic shift mimics caloric restriction and exercise adaptations - similar to other AMPK activators (metformin, berberine, exercise itself).,Pterostilbene also has direct antioxidant activity (free radical scavenging via the polyphenol structure - more potent than resveratrol per mole), modulates Nrf2 pathway (cellular antioxidant defenses), inhibits NF-kB (anti-inflammatory), and has neuroprotective effects via reduced neuroinflammation and improved blood-brain barrier integrity. The methylation pattern reduces estrogen receptor binding compared to resveratrol, decreasing phytoestrogen activity - relevant for hormone-sensitive populations who may want pterostilbene's pathway benefits without the estrogenic profile.

Pharmacokinetics
Storage. Store at room temperature (20-25C) in a cool, dry, dark place. Pterostilbene is more stable than resveratrol due to the methoxy groups but still light-sensitive. Capsules shelf-stable for 24+ months. Keep in opaque containers.
Regulatory status
Classified as a dietary supplement in the US (no FDA pre-approval required). Available widely over the counter. EU permits pterostilbene as a food supplement. ChromaDex's pTeroPure (the most-studied commercial form) has GRAS self-affirmation. Major branded products include Basis (Elysium) which combines pterostilbene with NR.
