No Jitters No Crash

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.
