An article in this month's edition of the British Medical Journal has highlighted a growing number of cases reported by Doctors and Surgeons involving the very same side effects from the 70s. All of the patients examined were regular drinkers of RedBull and it is believed that the safety of Glucuronolactone is currently under review in at least three major European countries."
Every word of that is a lie. Really, every single word. Well, maybe except the part about Red Bull containing glucuronolactone.
The chemical was not invented by the government (it occurs naturally in the body). The whole Vietnam story is a lie, the British Medical Journal article does not exist and the FDA doesn't have shit about glucuronolactone being dangerous.
Now, there was this one kid who drank three Red Bulls in a row and then died some hours later, which caused some countries to ban the product. Though this means that the brain tumor theory is out (unless he magically grew a tumor so huge that it gave him a heart attack--but we're pretty sure they would have mentioned that).
As for glucuronolactone, a can of Red Bull does contain 600 mg of the stuff, which is 250 times a person's normal intake. What are the effects? Nobody knows. The reason there are so many rumors about it is that there have been almost no studies into what it actually does. We don't even know if it actually gives you energy.
Maybe this is what Red Bull is for.
The same can be said for the other key ingredient, taurine. In some cases it even acts like a sedative.
So how does a can of Red Bull give you that burst of energy? Check out the amount of sugar and caffeine on the label. If you want a reason not to drink it, why not that?
