Johns Hopkins Health - Caffeine Fix

Winter 2009
Issue No. 3

Caffeine Fix

Date: January 24, 2009

So-called energy drinks on the market may be doing consumers a disservice, say Johns Hopkins scientists who have spent decades researching the effects of caffeine. They are calling for prominent labeling that notes caffeine doses and potential health risks for consumers.

Caffeine content of energy drinks varies, with some containing the equivalent of 14 cans of Coca-Cola, says Johns Hopkins researcher Roland Griffiths, Ph.D. Without labeling, he adds, consumers—typically the teens and young adults who are targeted by energy-drink ad campaigns—don’t know what they’re getting.

“It’s like drinking a serving of an alcoholic beverage and not knowing if it’s beer or scotch,” Griffiths says.

Griffiths and colleagues are currently collecting case reports of caffeine intoxication from energy drinks in children and adolescents.
