Red Bull

Proprietary “energy drink” developed in Austria based on a Thai beverage product Krating Daeng. Red Bull is primarily a high caffeine, high sugar soft drink, but it features the organic compound Taurine, which is a source of some controversy. Energy drink is generic for a water beverage featuring an assortment of stimulants—almost always large quantities of caffeine or other methylxanthines—and other ingredients such as vitamins and alleged dietary supplements. Usually carbonated and sweetened.
