Brain-boosting supplements - real or fake?
Some of the mental clarity supplements known as nootropics have brain-boosting capacity.
Natural or man-made substances designed to support cognition and mental performance.
Caffeine, omega-3 fatty acids, gingko biloba and few other nootropics may have benefits.
Taking one or two of these nootropics will not result in a significant change.
Researchers suggest taking a concoction of most researched and validated supplements.
Experts say that nootropics are harmless but unnecessary.
Exercise, healthy diet and good sleep are great for improving mental clarity and memory.
