Red Bull plus alcohol can kill you.
The popular energy drink that claims "it gives you wings" is a popular mixer with alcohol. Fans of the drink believe it helps them party longer. But there are a couple of reports of people who died after consuming Red Bull mixed with alcohol.
There isn't any proof that Red Bull is the cause of these deaths. But people who regularly mix alcohol with Red Bull may be setting themselves up for a potentially dangerous scenario.
One can of Red Bull contains 80 mg of caffeine...the same as in one cup of coffee. It also contains taurine, an amino acid that also seems to have stimulant effects.
