Pterostilbene

Pterostilbene is a plant compound found in blueberries, closely related to resveratrol, that acts as an antioxidant in the body. People mostly look at it for heart health, and in a small study of 80 people with coronary artery disease, blood pressure improved, though the evidence is limited. In 215 people, blood glucose showed no clear difference, and that evidence is very limited too.
