Gamma- Amino butyric acid (GABA) is an amino acid, synthesized from glutamic acid and acting as a neurotransmitter in the central nervous system.
Neurotransmitters fosters communication between nerve cells.
GABA has an inhibitory function and helps to keep stress-related nerve impulses at bay. It stabilizes or slows down the firing of neurons, calming nervous activity and excitation. Irritability, restlessness, insomnia, seizures and movement disorders are all linked to too much excitation, indicating the importance of inhibitory or calming neurotransmitters.
GABA deficiency is associated with several psychiatric and neurological disorders, including anxiety, mood disorders, insomnia, depression and epilepsy. Several studies illustrate the use of GABA to enhance sleep and improve relaxation, by reducing excitability.
Other parts of the body uses GABA mainly to regulate muscle tone and for its sought after effect on human growth hormone. HGH stimulates cell production and regeneration, and can improve vision, energy levels, cognitive function, immune function, decrease recovery times and reduce body fat.
How it works:
GABA exerts its main action by binding to GABA-specific receptors on neurons, causing hyperpolarisation of the nerve cell. By making the membrane potential of the cell more negative, it makes it more difficult to stimulate the cell, thus inhibiting its action.
By regulating the excitability of the brain, as well as having an effect on the endocrine system, hormone levels and endorphin production, GABA helps promote relaxation, ease nervous tension and acts as a calming agent.
Foods don't contain GABA, but its building block, L-glutamine can be found in
