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

'We Tried It' -

"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"
