A flawed article.  Many energy drinks contain far more caffeine than Red Bull (Rockstar is 180 mg, for example), to say nothing of the ‘5 hour energy’ drinks that are over 200.

What’s more, sports drinks like Gatorade not only have no caffeine, they are also available in sugar free varieties.  And the hospital once recommended Gatorade for my 10 year old son when he was recovering from a bout of diarrhea.  (Yes pedialyte is better – but has anyone, ever, successfully gotten a child to drink that stuff?)
