I have been asked several times what is in Red Bull. If you look on the can you can find out what is in the drink, however you cant find out the amounts. I really wanted to know the answer to this so I have been reasearching on line for a while and those folks at Red Bull must keep the answer in a vault. So I e-mailed them last week and they still ahvent responded. If anyone is interested in an energy drink that tastes great, is full of Taurine, and is cheaper than Red Bull, please send me an e-mail and I will direct you in the right direction. patricorussell@yahoo.com
