GABA is a key calming neurotransmitter in the human nervous system that is also found in some foods. GABA acts to relax the nervous system by preventing overstimulation. GABA decreases stress-related beta waves and increases the production of alpha-waves in the brain which are related to lowered stress levels. Other ingredients in Relaxify also positively influence GABA, like Suntheanine®, Taurine and Magnesium.
