One of the key ingredients of Red Bull is Taurine.
Wikipedia says this about Taurine:
"Taurine is often used in combination with performance enhancing substances, such as creatine and anabolic steroids, partly due to recent findings in mice that taurine alleviates muscle fatigue in strenuous workouts and raises exercise capacity."
SOUNDS LIKE RED BULL, EH?
Also "Taurine is named after the Latin taurus, which means bull or ox, as it was first isolated from ox bile in 1827 by German scientists Friedrich Tiedemann and Leopold Gmelin."

So like, there is a direct link between the product's name, and the fact that there is Taurine in it.
I mean, taurus ---> Taurine ---> Red Bull/Taurus.

Do you:
a) AGREE that this is how Red Bull got its name
b) DISAGREE and think it is just a happy coincidence
