Calm Eze has been formulated with L-Theanine (from Suntheanine®) and gamma-aminobutyric acid (GABA), two ingredients that act as natural anxiolytics by increasing levels of GABA in the brain.◆ When GABA levels increase in the brain, excitability decreases and relaxation ensues. Research also suggests that GABA administration significantly increases alpha waves and decreases beta waves in the brain, thereby reducing anxiety.
