There is a lot of confusion about RedBul and taurine. Indeed, there is taurine in redbull, but it is definitely not the taurine making all the damange to the cardio-vascular system. For some reason people don't stop to think that a huge amount of stims and sugar are really bad for one's health, and taurine has nothing to do with it. Well, there is only one possibility of taurine in redbull being harmful - if you drink roughly more than 4-5 cans per day. Each can has, if I am not mistaken, 1 gram of taurine, and the recommended daily dosage for an adult male is 3 grams. So drinking more than 3 cans per day would be like overdosing with taurine, which is not good, especially coupled with caffeine and sugar.
