Next month, several chain supermarkets in the UK will stop selling energy drinks to customers under 16. Anyone looking to buy a soft drink with more than 150 milligram of caffeine per liter—a limit targeting drinks like Monster and Red Bull—will need to present an ID.
    The retailer Waitrose announced its new energy drink restrictions first in early January. Sainsbury’s, Morrisons, Lidl, Coop, Asda, Aldi and Tesco followed with their own bans on selling the drink to children, which will all roll out at the beginning of March.
    And while a nationwide soda tax will go into effect in the UK in April, banning so-called "under 16s“ from buying energy drinks is a voluntary measure that grocery stores have taken up this year.
    It’s probably a good idea to pause energy drink sales to children, says Jennifer Temple, a nutrition researcher at the University of Buffalo.
    Small to moderate doses of caffeine haven’t had a huge effect on kids in Temple’s research, but she’s not enthusiastic about supplying children with energy drinks. A major aim of caffeine-preventing sleep-can interfere with the rest kids need to grow, think and function. "There’s no reason why kids need this caffeine,“ she says. "The sleep effects alone are something that we should be mindful of. ”
    Researchers, teachers and those policy groups count the energy drink bans for kids in grocery stores as a victory, but they’re not a perfect, principle solution. The issue with it is that these products will still be bought in convenience stores and other small stores.
