What is Pterostilbene?
Dimethyl ether of resveratrol from blueberries. Far superior bioavailability (80%) vs resveratrol (20%).
How Pterostilbene works
Methylated resveratrol analog that resists rapid metabolism, achieving significantly higher plasma levels and longer duration of SIRT1, AMPK, and Nrf2 activation. Crosses the blood-brain barrier more readily than resveratrol.
Benefits & uses
Common uses: SIRT1 activation, neuroprotection, blood sugar regulation, cardiovascular health, longevity.
Pterostilbene dosage
