As mentioned above, Diet Dr. Pepper has 36mg of caffeine. Energy drinks like Celsius have 200mg of caffeine per can. Therefore, if you drink caffeine regularly, Diet Dr. Pepper will only give you a small boost.

Diet Dr. Pepper vs. Other Sodas

As mentioned above, Diet Dr. Pepper has about 36 mg of caffeine per can. However, Diet Dr. Pepper is the exception when compared to sodas like Sprite, Root Beer, and Sierra Mist. All three of these sodas are caffeine-free.

Diet Dr. Pepper is also a carbonated drink, but it does not contain any sugar. It gets its sweetness from aspartame, a type of artificial sweetener.

Diet Dr. Pepper vs. Coffee

Diet Dr. Pepper contains significantly less caffeine than coffee. Coffee can contain up to 200 milligrams of caffeine. This means that Diet Dr. Pepper has about 18% of the caffeine of coffee. While Diet Dr. Pepper is not as high in caffeine as coffee, it does still contain enough to give you a boost. If you are looking for a drink that will give you more of a caffeine kick, coffee is the way to go.

Diet Dr. Pepper vs. Black Tea

Diet Dr. Pepper's caffeine content is similar to that of tea. Black tea contains around 47 milligrams of caffeine while Diet Dr. Pepper has 36 milligrams. However, black tea is healthier, because it does not use artificial sweeteners. Tea also has a slightly bitter flavor which can make it an acquired taste.
