I was actually discussing the safety thing with my DJ last week - concerning
how the stimulant prevents the bodies natural defenses from saying 'that's
enough' and ejecting the poison.
Also we were somewhat bemused about the bull-derivative thing, and I couldn't
believe it was really a testicle extract. He'd heard it was from bull urine.
Um, anyway.
Studying the can we came across a wealth of warnings about limiting the amount
drunk, and to never under any circumstances to mix it with alcohol!
Which was quite a surprise, seeing as that's the only way we ever serve it ;)
It's also recommended ONLY for people with an extremely active lifestyle -
body builders and professional athletes.
This warning is NOT repeated on the redbull website AFAICS.
Anyway, it may have something to do with Euro labelling laws, but it's
astonishing that this was printed clearly on the can itself without this
rumour(fact) getting more airplay.
The can was BTW manufactured in Austria and printed in Greek.
Snopes had no more info on this avenue of inquiry
