GABA (Gamma-Aminobutyric Acid) Neurotransmitter
What is GABA?
GABA, or gamma-aminobutyric acid, is the most abundant inhibitory neurotransmitter in the brain. While GABA is an amino acid, it is classified as a neurotransmitter and helps induce relaxation and sleep. It balances the brain by inhibiting over-excitation. GABA contributes to motor control, vision, and many other cortical functions. Anxiety is also regulated by GABA. Some drugs that increase the level of GABA in the brain are used to treat epilepsy and to calm the trembling of people suffering from Huntington’s disease.
Gamma-aminobutyric acid also stimulates the anterior pituitary, leading to higher levels of Human Growth Hormone (HGH). Human Growth Hormone contributes significantly to muscle growth and also prevents the creation of fat cells. Moreover, HGH depletion is prevalent in adults over the age of 40 may be responsible for sleep disturbances or interupted sleeping patterns.
Natural alternative medicines have been shown to act directly on the GABAnergic system, allowing for greater availability of this neurotransmitter. This effect is believed to be partially responsible for improvement in those individuals taking natural alternative GABA antagonists like Valerian root.
