  Nootropics also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals, and functional foods that purportedly improve mental functions such as cognition, memory, intelligence, motivation, attention, and concentration.

• Nootropics are thought to work by altering the availability of the brain’s supply of neurochemicals (neurotransmitters, enzymes, andhormones), by improving the brain’s oxygen supply, or by stimulating nerve growth.
