Description Specification Recommended Usage GABA (gamma-aminobutyric acid) is an amino acid which acts as an inhibitory calming neurotransmitter to regulate brain and nerve cell activity by inhibiting the number of neurons firing in the brain. GABA is referred to as the "brain's natural calming agent", and by inhibiting over-stimulation of the brain, GABA may help promote relaxation and ease nervous tension. Taken at bedtime, supplemental GABA may assist some people in the initiation of sleep and produce a deeper and more beneficial sleep. Can promote healthy sleep. Supports smooth involuntary movement. Supports a relaxed state of mind. Supports healthy resting growth hormone release after exercise. Low levels of GABA may impact mental health in a negative way. Gamma-aminobutyric acid (GABA) is major neurotransmitter widely distributed throughout the central nervous system (CNS). This neurotransmitter appears to have a significant influence on the pituitary gland's hormone secretion, primarily through its hypothalamic effect. GABA is also the most important and widespread inhibitory neurotransmitter in the brain. It helps prevent the over-firing of the nerve cells and decreases overall neuron activities in the CNS. Over-firing can cause restlessness, spasmodic movements, irritability and anxiety. GABA is also utilized by the brain to create tranquility and calmness through the brain's metabolic processes.
