Energy drinks need warning labels.

Caffeinated energy drinks should carry prominent warning labels noting health risks to consumers, according to several scientists who have spent decades researching the effects of caffeine.

"The caffeine content of energy drinks varies over a tenfold range, with some containing the equivalent of 12 cans of Coca-Cola, yet the caffeine amounts are often unlabeled and few include warnings about the potential health risks of caffeine intoxication," said Roland Griffiths, PhD, an author of an article published online Sept. 21 in Drug and Alcohol Dependence.

A regular 12-ounce cola has about 3 milligrams of caffeine, and six ounces of brewed coffee has 80 milligrams to 150 milligrams. The caffeine content of energy drinks, according to the article authors, varies from 50 milligrams to more than 500 milligrams.
