GABA or gamma-aminobutyric acid occurs naturally in your brain, where it functions as a neurotransmitter and helps regulate brain activity. It is also needed in other parts of your body, where its most important function is regulating muscle tone.
Unlike other neurotransmitters, GABA has an inhibitory function – it tends to slow down neuron firing. Other neurotransmitters – adrenaline, nor-adrenaline, dopamine, serotonin, glutamate – have an excitatory function, i.e. they stimulate neuron firing. It's important to remember this difference when you are deciding which is the best supplement to take for anxiety or depression.
We know that low levels of GABA are associated with anxiety. There are many people who find that boosting GABA with a supplement definitely helps relieve anxiety.
