Pterostilbene is a substance that naturally occurs in grapes and berries. While it has long been renowned for it’s cardiovascular benefits, research has shown it to also be a nootropic.
What Is Pterostilbene?
Pterostilbene is a naturally occurring substance found in blueberries and grapes. It is classified as a phytoalexin meaning plants produce it to fight off various types of infections. It is well known for having various health benefits including reduction of cognitive decline due to aging, lowering cholesterol levels, and anti-cancer effects. Agnes Rimando, a chemist at ARS’s Natural Poducts Utilization Research Laboratory in Oxford, Mississippi stated:
“The more we study Pterostilbene, the more we see its huge potential in the human health field”
Pterostilbene Dosage Information
The suggested daily dosage is between 100 to 250mg for adults. You should reach these amounts by taking a single 50 to 125mg capsule twice daily. 
How Does Pterostilbene Work?
Pterostilbene is known to bind to the PPAR-alpha receptor. This receptor plays a major part in the regulation of lipid metabolism in the liver and activation of this receptor promotes catabolism of fatty acids. 
This nootropic is known to inhibit the enzyme cytochrome P-450 which is known to activate various chemical carcinogens giving Pterostilbene anti-cancer properties.
Safety and Side Effects of Pterostilbene
This nootropic is regarded as being completely safe and there have been no reported side effects.

That being said, this nootropic isn’t going to make you smarter, more focused, or increase your energy in the short run. It is more a preventative nootropic then a pro-active one. If you want results now and aren’t worried about the mentioned areas of health then you might as well pass on Pterostilbene.
The Journal of Neuroscience published an article stating that a diet high in the blueberry extract, Pterostilbene reverses mental, nerve, and muscular decline in older rats. Co-author Barbara Shukitt-Hale, PhD, a researcher at the U.S. Department of Agriculture stated “What we found was that especially the blueberry diet reversed some of the age-induced deficits in motor behavior. All the diets actually helped with cognitive, or learning and memory, behavior” These rats were the equivalent of 70-75 in human years and were subjected to various Pterostilbene diets for 8 weeks.
