Pterostilbene is found in almonds,[2] various Vaccinium berries,[3] grape leaves and vines [1][4] and blueberries.[5][6]
While resveratrol is under research for its potential properties from consuming wine and other foods or beverages, pterostilbene is not found in wine.[7]
Basic research
The possible biological effects of pterostilbene are being examined in basic research involving laboratory models of several disorders, including age-related cognitive decline.[8]
