Red Bull’s creators have asserted that the taurine in its drinks is completely synthetic. Conspiracy-minded ‘Bull heads have debated whether the taurine in their afternoon pick-me-up is derived, specifically, from bull testicles (in wilder circles, the speculation extends to bull semen and urine), a rumor that probably stemmed from a misunderstanding of what its original source fluid, bile, actually is - the moss-hued slime produced by the gall bladder, anatomical miles away from bull genitalia. Known in scientific circles as 2-aminoethanesulfonic acid, the compound was named after the Latin taurus, for bull, after German scientists isolated it from ox bile in 1827. Sure, taurine can have that effect, but it achieves it through much less direct means.įirst, a bit about taurine itself.
