What Is GABA?

GABA is a neurotransmitter found in the central nervous system.  Since its discovery as such an important part of our central nervous system is has been synthesized and is currently sold as a supplement. It is a popular supplement among body builders that is also purchased for people seeking to improve mood and lower anxiety. Even though there are over 43,000 published papers on PubMed today a very select few focus on GABA’s use as an oral supplement.

GABA Dosage Information

The appropriate dose of GABA depends on factors such as the user’s age, health, and weight. Even though there is no suggested dosage for GABA there are reports of it being successful at certain dosages.

For those people attempting to increase their HGH a dosage between 3 – 18 grams daily has proven successful. [1] For those trying to treat anxiety or fight insomnia a dosage of 500mg to 1000mg is recommended. When taking GABA to help with insomnia it is best to take it right before sleep.

How Does GABA Work?

GABA plays a role in regulating neuron excitability throughout the entire central nervous system. GABA works as an inhibitory neurotransmitter. Other neurotransmitters communicate with synapses in the brain by fitting into certain receptors and “firing” an electrical impulse that is then interpreted by the brain. GABA does the opposite; it fits into certain receptors to block other neurotransmitters from firing off their impulses. This inhibitory neurotransmitter, along with many others, is very important for regulating the brain. Without GABA certain nerves would fire too often. This can lead to anxiety disorders including panic attacks, and seizures. [1]
