Pterostilbene is similar to piceatannol, see yesterday’s blog post, which is a supplement structurally similar to resveratrol. Pterostilbene, compared to piceatannol, seems to be significantly better absorbed in the intestinal tract and also serves as a more powerful antioxidant.
Though pterostilbene has been researched less than piceatannol, it is potentially more promising. Preliminary rat evidence suggests that the antioxidant and anti-inflammatory effects can reach the brain, providing benefits to cognition in aged rats. The dose studied is low enough that it could partially explain the benefits seen with blueberry consumption, which is normally attributed to anthocyanins, a different set of molecules. We look forward to human studies to confirm these benefits.
