Pycnogenol, an antioxidant extract from the bark of French maritime pine trees, can increase cognitive power.
According to the March ’12 Better Health, subjects taking pycnogenol had improved test scores and overall mental performance compared to those who didn’t get the compound.
The study was published in the Italian journal Panminerva Medica, and the subjects took 100 milligrams of the supplement each day. Attention and mood also improved.
Another study, published in the Journal of Psychopharmacology, found that pycnogenol improved the memory of Australian seniors.
