Energy drink

Energy drink, any beverage that contains high levels of a stimulant ingredient, usually caffeine, as well as sugar, and often supplements, such as vitamins or carnitine.

Energy drinks are beverages whose producers say they can "can boost energy". This claim has to do with vitamins and stimulants in these drinks. Examples of energy drinks are Red Bull and Monster Energy. They are usually well liked by young people. 66 percent of energy drink sales are to people between the ages of 14 and 35.[source?]
