Pterostilbene on Metabolic Parameters: A Randomised, Double-Blind, and Placebo-Controlled Trial
Year: 2014 • 80 adults with elevated cholesterol • Duration: 6–8 weeks • Randomised controlled trial
High-dose pterostilbene (125 mg twice daily) lowered systolic blood pressure by 7.8 mmHg and diastolic by 7.3 mmHg versus placebo; lipid effects were mixed, with LDL rising modestly when pterostilbene was taken without grape extract. View on PubMed →

Analysis of Safety From a Human Clinical Trial With Pterostilbene
Year: 2013 • 80 adults • Duration: 6–8 weeks • Randomised controlled trial
Pterostilbene at up to 250 mg daily produced no clinically significant adverse effects on liver, kidney or blood safety markers compared with placebo. View on PubMed →

Frequently Asked Questions
Everything you need to know about our premium supplements
Pterostilbene is resveratrol's more bioavailable cousin. It has superior absorption (80% vs 20%), a longer half-life in the body, and better cellular uptake. It provides similar longevity benefits but with enhanced potency at lower doses.
Pterostilbene easily crosses the blood-brain barrier, providing direct neuroprotective benefits. It supports cognitive function, protects brain cells from oxidative stress, and may enhance memory and mental clarity. It's one of the most promising brain-healthy antioxidants.
Yes, many people stack both for comprehensive longevity support. They work through similar but slightly different mechanisms. However, Pterostilbene alone may provide sufficient benefits given its superior bioavailability. Start with one and add the other if desired.
Our capsules provide 500mg of pure trans-pterostilbene per capsule, which is a potent therapeutic dose for cognitive and longevity benefits. Take 1 capsule daily. Due to its high bioavailability (4x better than resveratrol), this dose provides significant antioxidant and neuroprotective support.
