Curious about how drinks stack up against each other in caffeine? You may be surprised to find it’s not just drinks that contain caffeine. For example, 2 extra strength Excedrin have almost twice the caffeine as one cup of coffee. Instant coffee contains almost half the caffeine as brewed coffee. Energy drinks have twice the caffeine as Coca-Cola Classic, and 5-hour energy drinks contain almost 7 times the caffeine of Coca-Cola. Ever wonder why you can’t sleep at night, think about the sources of caffeine and if you may be getting too much in your day. Coffee, tea, green tea, Root Beer, Chocolate, Excedrin, decaffeinated coffee, chocolate candy, and energy drinks all contain caffeine.
There are no labeling laws requiring manufacturers to list the amount of caffeine in products. So it may be up to you, the consumer, to research this information.
