Benefits of Pterostilbene

Evidence-Based Benefits

• Superior bioavailability — pterostilbene's two methoxy groups (replacing resveratrol's hydroxyl groups) increase lipophilicity and metabolic stability, yielding ~80% oral bioavailability versus resveratrol's <1% (Kapetanovic et al., 2011)
• Blood pressure reduction — Riche et al. (2014) conducted a randomized, double-blind trial showing pterostilbene at 125mg 2x daily significantly reduced systolic and diastolic blood pressure in adults
• Lipid oxidation — pterostilbene reduces LDL oxidation and modulates cholesterol metabolism; the same trial showed favorable effects on lipid profiles at the lower 50mg dose
• SIRT1 activation — like resveratrol, pterostilbene activates SIRT1 deacetylase and stimulates AMPK, mimicking caloric restriction at the molecular level
• Neuroprotection — Chang et al. (2012) demonstrated pterostilbene improves working memory and reduces anxiety in aged rats, with enhanced hippocampal function and reduced oxidative stress

What the Research Says

Pterostilbene is increasingly viewed as a practical upgrade over resveratrol due to its dramatically superior pharmacokinetics. Kapetanovic et al. (2011) established the favorable bioavailability profile. Riche et al. (2014) published the most significant human trial, demonstrating blood pressure reduction and cardiovascular benefits. Chang et al. (2012) showed cognitive benefits in aging animal models. McCormack and McFadden (2013) provided a comprehensive review of pterostilbene's anticancer, anti-inflammatory, and metabolic properties. The main concern from the Riche trial was a dose-dependent increase in LDL cholesterol at the highest dose (250mg 2x daily), which warrants monitoring.
