Most energy drinks contain far more caffeine than the limit set by the Food and Drug Administration (FDA) for carbonated colas. (Energy drinks are not included in the FDA regulation that limits caffeine in other beverages.) However, caffeine content is not disclosed on beverage labels, so energy drinks may pose a health threat to consumers who should limit their caffeine intake. That includes those with high blood pressure, pregnant women or people with certain psychiatric diseases or anxiety conditions. They may unknowingly ingest too much caffeine if they consume energy drinks. In certain people, caffeine can cause anxiety, palpitations, irritability, difficulty sleeping and stomach ailments. |
