nootropic

adjective Referring to a nootropic agent.
 
noun Any agent—drug, functional food, nutraceutical or nutritional supplement—which is thought to improve mental function, including attention, cognition, concentration, memory or motivation, allegedly by increasing the availability of neurotransmitters, enzymes or hormones, and by increasing O2 delivery or stimulating neural activity.

There is little clinical evidence that most agents advertised as nootropics actually work as advertised.
