Gamma aminobutyric acid (GABA), is a neurotransmitter made from the amino acid glutamate. GABA is the chief inhibiting, or calming neurotransmitter in the brain, functioning as a brake on the neural circuitry during stress. Low GABA levels are associated with restlessness, anxiety, insomnia and a poor mood. GABA works to balance glutamate (excitatory) in the brain. GABA is the brake pedal on a car while glutamate is the gas pedal.
