Bad news, energy drink addicts: The wildly popular beverages – they make up the fastest-growing portion of the drink industry – are, when it comes down to it, just “caffeine delivery systems,” explains one expert.
Others agree with him, the New York Times reports in an extensive look at the drinks. Sure, energy drinks claim to be “scientifically formulated” and sometimes include fancy-sounding ingredients or tons of vitamins, but their only truly proven element is caffeine. And you could get the same amount of that for much less money by just buying a cup of coffee.
Experts have found those other ingredients, including B vitamins, offer little or even no established benefit to drinkers.
Two of the much-touted ones that the Times zeros in on are glucuronolactone (related to glucose) and taurine. The former has barely been tested, save for two 40-year-old Japanese studies; a European regulatory group decided health claims about the latter weren’t backed up by science.
