Natural occurrenceEdit

Pterostilbene is found in almonds,[2] various Vaccinium berries,[3] grape leaves and vines [1][4] and blueberries.[5][6]

ResearchEdit

The possible biological effects of pterostilbene have been examined in basic research involving animal models of several disorders, including age-related cognitive decline, and some clinical trials have been run.[7]
