Zest Tea is a line of cognitive and energy boosting teas. Zest’s premium tea blends have comparable caffeine levels to coffee, for an energizing kick, and amino acids shown reduce the jitters and crash while boosting cognitive functions. The result is a steady and prolonged focus.


Zest Tea Caffeine Levels

155mg / cup

Zest tea has as much caffeine as a cup of coffee, or about 3x the levels of normal teas. We use a proprietary blending process and natural caffeine extract to enhance the caffeine levels of our teas.

Our biggest concern when developing these teas was maintaining the delicious flavor profiles of our base teas. If you look at our reviews you'll see that we accomplished this task. Our teas are applauded as much for their premium flavors as they are the enhanced energy levels!

"We felt 'in the zone' almost more clearheaded than we would normally be with coffee... It definitely hits you harder, but I didn't get jittery or anything"

Focused Energy

The combination of the caffeine and L-Theanine (a rare amino acid) in Zest Tea has a synergistic effect that prolongs the energy levels and creates a more steady alertness. A side effect of the energy moderation is a reduction in the "jitters" and "crash" that typically accompanies caffeinated beverages.  

L-Theanine and Caffeine No Jitters No Crash
