If you are feeling low-energy, then grabbing a drink to wake you up can sound appealing. However, the dangers of energy drinks are still being reported. Caffeine overdose from these drinks can lead to a number of symptoms, including neurological and cardiovascular effects on children and adolescents.
Beyond caffeine, energy drinks contain several ingredients (B vitamins, guarana, taurine, carnitine) that have yet to be studied long-term. Negative health effects are still being discovered, so drink with caution.
