Fact or fiction?

I drink two Red Bulls a day. Most of my friends are into energy drinks, too. They're not bad for us, right?

Wrong! Drinks such as Monster, Rockstar, Pimpjuice and, yes, Red Bull can be harmful. They're packed with sugar and caffeine, and many are loaded with B vitamins, which, in large quantities, can cause rapid heartbeat. In recent years, poison control centers have reported an increase in caffeine overdoses. Some drinks also have mega-doses of ingredients like taurine that haven't been FDA-approved. To be safe, kick the habit or stick to one a day.
