Widely disseminated in the popular culture of late, even making appearances in blockbuster movies, the so-called 'Smart Drugs' and nootropics are not only the subject of much chatter but, large numbers of people are trying them as they are widely available OTC and online.  Academic research has been limited and mainly restricted to use in neurological conditions and age-related dementia but there is abundant anecdotal evidence that overwhelmingly supports their beneficial effects in improvement of cognitive function among youthful, healthy folks.  Do you suffer from "Brain Fog", memory impairment, lack of focus, etc.?  Perhaps you should see me for an evaluation -- there may be a "Smart Drug" with your name on it!
