Energy drinks are soft drinks advertised as providing more energy than a typical drink. The amount of quantitative 'energy' (as measured in calories) in these drinks is often lower than that in regular soft drinks. There is no scientific basis for concluding that the non-caffeine elements in these drinks contribute to either mental alertness or physical performance.
The average 237 milliliter (8 fluid ounce) energy drink has about 80 mg of caffeine, about the same as a weak cup of coffee, with 480 ml (16 fl. oz.) drinks containing around 150 mg, although recent drinks have containing as much as 344 mg of caffeine. These drinks are typically attractive to young people. Approximately 65% percent of its drinkers are younger than 35 years old, with males being approximately 65% of the market.
