Healthy lifestyle choices and wise supplements are key to improving memory for studying. Begin by getting enough sleep, working out often, and eating a healthy, balanced diet high in antioxidants and omega-3 fatty acids. Use spaced repetition and active memory strategies, and divide study periods into digestible portions. Focus can also be improved by avoiding distractions and drinking enough of water. To improve alertness and cognitive performance, some people use Modvigil 200, a kind of modafinil. By improving focus and lowering weariness, it could indirectly improve memory. Modvigil is not a replacement for regular study habits and a healthy lifestyle, though, and should only be taken under a doctor's supervision.
