Scientists who have spent decades researching the effects of caffeine have stated that a slew of caffeinated energy drinks now on the market should carry prominent labels that note caffeine doses and warn of potential health risks for consumers.
Some energy drinks contain the equivalent caffeine of 14 cans of Coca-Cola, yet the amounts are often unlabeled, and few include warnings about the potential health risks of caffeine intoxication.
Caffeine intoxication is marked by nervousness, anxiety, restlessness, insomnia, gastrointestinal upset, tremors, rapid heartbeats (tachycardia), psychomotor agitation (restlessness and pacing) and in rare cases, death.
