Especially in young kids, it doesn't take a lot of caffeine to produce these effects. What Other Problems Can Happen?Here are some other reasons to limit kids' caffeine consumption:
What Is Caffeine Sensitivity?Caffeine sensitivity refers to the amount of caffeine that will cause an effect in someone. Caffeine sensitivity is mostly related to daily caffeine intake, but the smaller the person, the less caffeine is needed to produce side effects. Kids are more sensitive to caffeine than adults. People who regularly drink beverages containing caffeine soon become less sensitive to it. This means they need more caffeine to achieve the same effects as someone who drinks less caffeine.

Energy drinks may also contain sugars, vitamins, herbs, and supplements. Companies that make energy drinks claim that the drinks can increase alertness and improve physical and mental performance.
