Where does an energy drink get its energy?
In versions that contain sugar, the sugar supplies dietary energy as carbohydrate. Sugar free versions may contain caffeine and vitamins but provide no energy from sugar.
Is caffeine the same in every drink?
Yes. Caffeine is chemically the same compound whether it comes from coffee, tea, cola or an energy drink. The amount and serving size may differ, so count caffeine from all sources together.
How much caffeine is in a can?
A typical 250 ml energy drink containing 32 mg of caffeine per 100 ml has approximately 80 mg of caffeine. Products are not all alike: always use the figure on the label.
Why are B vitamins included?
According to EU authorised health claims, vitamins B2, B3, B5, B6 and B12 contribute to normal energy yielding metabolism and to the reduction of tiredness and fatigue. Vitamins B2, B3, B6 and B12 also contribute to normal functioning of the nervous system. These claims can be used only for products that meet the relevant vitamin content conditions; check the current label.
Where did it start?
Lipovitan D, introduced in Japan in 1962, is regarded as an early modern energy drink. The product category therefore has a history of more than six decades.
Energy drink or sports drink?
The two types of drink serve different purposes. Sports drinks are primarily designed for fluid and electrolyte replacement; energy drinks are characterised by caffeine and, in sugar containing versions, dietary energy. Water remains the primary choice for hydration.
