Energy drinks contain a lot of caffeine. Caffeine is a stimulant that increases alertness and concentration. However, there are many different types of caffeine, and not all of them are safe. Some energy drinks also contain other ingredients like taurine, guarana, ginseng, yerba mate, and others. These ingredients can cause side effects when consumed in large quantities.
