WHAT YOU NEED TO KNOW:

What do I need to know about caffeine? Caffeine is a stimulant that gives you a burst of energy and keeps you awake. Caffeine can also raise your blood pressure and heart rate. Caffeine occurs naturally in cocoa beans, tea leaves, and coffee beans. It is also added to drinks, food, supplements, medicines, and herbal products.

What side effects does caffeine cause? Large amounts of caffeine may cause an upset stomach, shakiness, dizziness, headaches, and trouble focusing and sleeping. The amount of caffeine that would cause these side effects depends on how sensitive you are to caffeine. It also depends on how much caffeine you normally have. You may have side effects with only 1 cup of coffee if you normally do not have caffeine.

How much caffeine is safe? Caffeine is measured in milligrams (mg). A safe amount for healthy adults is less than 400 mg per day. Pregnant women should limit their caffeine intake to less than 200 mg per day. People with certain medical conditions, children, and older adults may be more sensitive to the effects of caffeine.
