Because expected?: Virtually all "energy drinks" have taurine but i know of no good evidence that taurine increases energy.Taurine is an Amino Acid that is important for heart health & muscles & acts as a inhibitory neurotransmitter, meaning it actually has a calming effect on the nervous system, the opposite of what you might want in an energy drink.But because it is widely used in these drinks people now expect it!
