Warning: You May Be Overcaffeinated

A 12-ounce cola has 35 mg of caffeine, but some of the newest energy drinks contain 14 times more—enough caffeine to lead to anxiety, insomnia, dehydration, stomach woes, or a dangerously fast heartbeat in some people (and it could pose special dan­gers to pregnant women). The risks are so worrisome that Johns Hopkins University scientists who have spent decades researching the effects of caffeine are pushing for warning labels. They say it makes no sense that over-the-counter supplements like No-Doz (which has 200 mg) require warnings, yet energy drinks that may have much more caffeine don’t. So how much caf­feine are you really getting? Check our chart.

What’s the Caffeine Count?
Energy Drinks 50–500 mg
Coffee 80–150 mg
Tea 47 mg
Soda 35 mg
