This document summarizes research on the effects of energy drinks on adolescents and young adults. It finds that energy drinks are popular among this group due to aggressive marketing targeting them. The main ingredients in energy drinks like Red Bull and Monster are caffeine, guarana, taurine, sugar, and bitter orange, which can have adverse effects in large amounts like nausea, anxiety, and hypertension. Studies show energy drinks may improve driving performance and reduce sleepiness if consumed before exercise, but more research is still needed on their safety and effects, especially on adolescents and young adults.
