Is the ingredient that has come under fire. Taurine is named after the Latin Taurus, which means bull. It was first isolated from ox bile in 1827 by Australian scientists Friedrich Tiedemann and Leopold Gmelon. It is often called an amino acid, even in scientific literature, but it lacks a carboxyl group it is not strictly an amino acid. Taurine is present in bulls livers, semen and urine. One thing is certain, the taurine used in energy drinks such as Red Bull is taken from these sources.
