If you're like most adults, caffeine is a part of your daily routine. But do you know the caffeine content of your favorite drink?

You may want to take a look at just how much caffeine you get in a typical day, especially if you're bothered by headaches, restlessness or anxiety. If your caffeine habit totals more than 500 milligrams (mg) a day, you may want to consider cutting back.

With the growing popularity of energy drinks, many parents have become concerned about how much caffeine their kids are getting. The American Academy of Pediatrics recommends that adolescents get no more than 100 mg of caffeine a day. Younger children shouldn't drink caffeinated beverages on a regular basis.

Check the charts below to see the caffeine content in popular drinks, sweets and medications. One note about the numbers: Use them as a guide. The actual caffeine content of the same coffee drink can vary from day to day -- even at the same coffee shop -- because of various factors, such as roasting and grinding as well as brewing time. The caffeine content of tea also is affected by how long it's brewed.
