ZumXR Release Logo


zümXR®’s targeted-release caffeine products mitigate the crash normally associated with caffeine consumption and deliver a more sustained and smooth caffeine experience. Three products are available with 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. Our liquid stable option offers a gradual six hour release.
