GABA
Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in your central nervous system (brain and spinal cord). It blocks or stops chemical messages from being sent to the next nerve cell. This causes nerve cells to have less of an effect. GABA also relaxes your muscles during sleep and sets your overall muscle tone.
