My advice to you is to eat foods that improved memory like blueberries, apples, spinach, grapes and eggplant. Also those foods for energy booster. But if in your diet, and if you preferred the taking of supplement. Take supp. that contain Ginkgo Biloba as it was the most effective and powerful antioxidants that you can find for your brain health. Great example of a particular supp. for improving memory and mental focus is the MX Brain Swift. Hope this info helps!
