If you need caffeine to get you through the day, you're not alone. About 83% of Americans in 2013 said they drank coffee, according to the National Coffee Association. Add the other sources of caffeine -- cola, energy drinks, and some medications and supplements -- and the number of caffeine consumers is even greater. So is this a bad thing?

Studies also show too much caffeine can set you up for high blood pressure, high blood sugar, and lower bone density -- not to mention jangled nerves. Follow the links below to find WebMD's comprehensive coverage about caffeine, the pros and cons, hidden dangers, and much more.
