How Much Caffeine Is Too Much for Teens?

That daily energy boost may be doing more harm than good.

While a regular cup of coffee contains around 80 to 100 milligrams of caffeine, many popular energy drinks contain double that amount. For teens, that’s pushing way past the safe zone.

High doses of caffeine can stir up more than just temporary alertness. We’re talking jitters, anxiety, and even irregular heart rhythms. If your teenager is regularly reaching for energy drinks just to keep up, it could be a sign that something deeper is going on.

A quick check-in with your family doctor can open the door to better sleep habits and smarter nutrition. It’s worth the conversation. Sometimes the best energy fix doesn’t come in a can.
