Spilling the Beans: How Much Caffeine is Too Much?

Article's Abstract

Do you drink coffee or tea first thing in the morning, hoping the caffeine in it will jump-start your day? Do you follow it up with more coffee, an energy drink, or other caffeinated beverages throughout the day?

According to medical experts, including here at the FDA, caffeine can be part of a healthy diet for most people, but too much of it can have negative effects and large amounts may pose a danger to your health. Depending on factors such as body weight, medications you may take, certain medical conditions, and individual sensitivity, “too much” can vary from person to person. Be aware of the level of caffeine in your diet and look out for signs when it’s too much.
