zümXR®’s time-release caffeine products mitigate the crash normally associated with caffeine consumption and deliver a more sustained and smooth caffeine experience. Two products are available with two distinctly different release profiles. The Delayed Release product delivers a shorter more pronounced caffeine experience, while the Extended Release product delivers a longer, steady release of caffeine.
zümXR® Delayed Release Caffeinea one-hour bolus, delayed release profile
zümXR® Extended Release Caffeinea four to five-hours sustained release profile
