The ideal cognitive enhancer supplement is determined by personal requirements and objectives, such as enhancing memory, attention, or mental clarity in general. A prescription drug called Modalert 200 (modafinil) is well known for being a powerful cognitive enhancer that increases alertness, attention, and productivity. It is especially beneficial for those who need constant mental alertness or who have sleep issues. Supplements such as omega-3 fatty acids, Bacopa monnieri, and L-theanine with caffeine are common non-prescription choices. When combined with caffeine, L-theanine improves attention without causing jitters. Bacopa monnieri may enhance memory and lessen anxiety, while omega-3 fatty acids promote brain function.
