The consumption of smart beverages began in the early 1980s when baby boomers started using because they believed these products would improve job performance and give them a competitive edge in the workplace.
Some of these drinks contain carbohydrates, such as glucose or galactose that are readily absorbed and converted into glycogen in the liver then transported by the blood stream for fuel for the brain.
Smart drinks are claimed to improve concentration, short term memory and mental acuity; so the ravers believed they could enjoy what they are experiencing even more.
Substances said to stimulate mental activities that are added to smart drinks include amino acids such as choline, L-cystine, L-cysteine, taurine, and phenylalanine.
