Keep in mind there has not been a randomized clinical trial and this is data from mice and monkeys ;)
And though I assume you are joking, some infos for anybody else interested: There have been studies on humans involving energy drinks, which showed bad results, driving up blood pressure, reducing blood flow in the brain, as well as possibly increasing the risk of fatal heart rhythms.
A “randomized, double-blind, controlled, crossover study” in which “young, healthy volunteers” were randomized to drink two large cans of an energy drink or a control drink that had the sugar and the same amount of caffeine, but none of the other “proprietary blend ingredients” like taurine, carnitine, ginseng, guarana, and all the other stuff they add.
That's interesting because I always considered those extra additives pretty harmless. So it's the mixture of everything which has negative side effects?
