ZHOU Energy + Focus Capsules, 60 CT

It's no secret that caffeine can provide some much needed energy throughout the day. That's why people turn to coffee and energy drinks when they need an extra boost. It's also no secret that these drinks come with a few side effects — they can leave you feeling jittery, stressed and over-stimulated. Not to mention the extra sugar associated with many drinks. Enter L-theanine, caffeine's natural soul mate. While caffeine is a stimulant, L-theanine is a non-protein amino acid that helps to calm down the stress-response produced by caffeine without limiting the energy boost. In other words, L-theanine brings out the best of caffeine and helps minimize the worst of it. With Energy + Focus you get a smoother, more focused energy boost.
