Pterostilbene is a natural dietary compound and the
primary antioxidant component of blueberries.
Pterostilbene has increased bioavailability in comparison to other
stilbene compounds, which may enhance its dietary benefit and possibly
contribute to a valuable clinical effect. Multiple studies have
demonstrated the antioxidant activity of pterostilbene in both in vitro and in
vivo models illustrating both preventative and therapeutic benefits. The
antioxidant activity of pterostilbene has been implicated in anti-carcinogenesis,
modulation of neurological disease, anti-inflammation, attenuation of va
