To boost memory and concentration, focus on lifestyle first. Regular aerobic exercises, like brisk walking or cycling, increase brain blood flow and stimulate cell growth. Mental exercises, such as puzzles or learning new skills, also keep the mind sharp.\n\nFor supplements, Omega-3 fatty acids, Vitamin B12, and Ginkgo biloba can support cognitive health, especially if you have nutritional gaps. Prescription medications (like methylphenidate or modafinil) are only recommended for diagnosed medical conditions like ADHD or narcolepsy, not for general enhancement. Please consult a doctor to discuss what is safest and most effective for you.
