Energy drinks claim to provide functional benefits by boosting energy and alertness. The functionality is obtained from ingredients such as glucose, caffeine or taurine. Energy is traditionally obtained from sugars; typically sucrose and glucose, and stimulants energy from such as caffeine, taurine and other ingredients, including inositol and B vitamins, are included to increase alertness.
Many of the ingredients commonly used in energy drinks can be found naturally in other foodstuffs. For example, taurine occurs naturally in seafood or poultry, while caffeine is a natural constituent of coffee beans, tea leaves, cocoa beans, kola nuts and guarana.
Energy drinks that have a high caffeine content are legally required to be labelled as having a high caffeine content. At EU level, the Consumer Information Regulation (EU) 1169/2011 which came into force in December 2014 contains provisions regarding the labelling of beverages with an added caffeine content of more than 150 mg/litre.
Over the last 25 years, energy drinks have experienced considerable growth in popularity and thus, are now consumed in most parts of the world. It is important that the sugar and caffeine content of energy drinks is clearly communicated to consumers.
