There is a common misconception that the popular energy drink RedBull contains urine or sperm from bulls, because it contains taurine. The myth stems from the fact that taurine was originally isolated from Ox bile (bulls and oxen are male cows) in the 1800’s. While initially identified in the bile (produced by the liver) of male cows, taurine is widely found in almost every organ in mammals. Taurine is chemically synthesized and used as an ingredient in infant formula, energy drinks, nutritional supplements, and pet food. Most recently it has been identified for its therapeutic value in the treatment of congestive heart failure and other cardiovascular diseases. It is currently being studied for its further use in the treatment of other diseases, in particular those relating to the nervous system, muscles, and mitochondrial disorders.
