Energy drinks are beverages with added caffeine. The caffeine content can vary widely, and labeling may not be accurate. They often contain sugar, vitamins, herbs, and supplements.
While energy drinks may improve alertness and physical endurance temporarily, they can be dangerous because of their high caffeine content and sugar levels, which can contribute to weight gain and worsen diabetes. Mixing energy drinks with alcohol is especially risky, as caffeine can mask intoxication and lead to poor decision-making.
