                                According to the brand's own information, Update Energy Drink does not cause jitters because its formula is completely caffeine-free. Instead of using traditional caffeine, Update uses paraxanthine, a purified metabolite of caffeine designed to deliver a cleaner energy boost without the negative side effects like jitters and crashes.
