What is pterostilbene
Pterostilbene is a natural compound primarily found in blueberries, grapes, and some other plants. It belongs to the stilbenes class, a group of phenolic compounds renowned for their antioxidant properties. Compared to resveratrol, pterostilbene offers better bioavailability, making it more easily absorbed and utilized by the body.
