Caffeine content for coffee, tea, soda and more

Introduction If you're like most adults, caffeine is a part of your daily routine. But do you know the caffeine content of your favorite beverages? And did you know that some sweets and even over-the-counter medications have caffeine? You may want to take a closer 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 to 600 milligrams a day, you may want to consider cutting back. Click the tabs to the left 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 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. |
