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 400 milligrams (mg) a day, you may want to consider cutting back.

The Dietary Guidelines for Americans (DGA) recommends that women who are pregnant and those who are breast-feeding check with their health care providers for advice concerning caffeine.

The DGA doesn't include guidelines for safe caffeine consumption for children. However, the American Academy of Pediatrics takes the position that stimulant-containing energy drinks have no place in the diets of children or adolescents.

Keep in mind that the actual caffeine content of a cup of coffee or tea can vary considerably because of factors such as origin, processing and preparation method, including brewing time. So use these numbers as a guide.
