Our brain naturally produces GABA, the main "calm and connect" neurotransmitter that inhibits or slows down nerve impulses. GABA supports rest and relaxation. L-theanine, an amino acid found in green tea, also facilitates relaxation and calm without affecting cognition. Together, they help maintain a balanced state. Each 2 ml of liposomal GABA with L-theanine delivers 250 mg of GABA and 100 mg of L-theanine. One serving is 4 pumps. Each bottle contains 25 servings. GABA (gamma aminobutyric acid) is an inhibitory neurotransmitter in the body that facilitates the calming and parasympathetic response of the nervous system.
