GABA, is a non-essential amino acid – the term 'non-essential' does not relate to its importance, but to the fact that this amino acid can be synthesized by the body as long as other nutritional factors are present. GABA primarily affects the brain, and, consequently, the emotions. Along with seratonin, it is one of the most important inhibitory neurotransmitters. Neurotransmitters in general are substances which cross the synapses between nerve endings and allow them to communicate more efficiently. As an inhibitory neurotransmitter, however, the way GABA works is by filtering out many of the extraneous signals that reach the brain at any given time. Where these are not filtered, anxiety or panic disorders are a common result. Consequently, GABA is considered a 'calming' neurotransmitter.
GABA's primary benefits relate to its function as a 'calming' neurotransmitter – it may effectively reduce anxiety, combat the effects of stress, and promote healthy sleep patterns. Individuals suffering from anxiety disorders, panic attacks or anxiety may in fact be experiencing the effects of low levels of GABA, or low GABA activity. Supplementing with GABA might benefit these individuals, and is a great alternative to pharmaceutical drugs. Moreover, there is evidence that GABA might also be effective in improving mental focus, and in treating conditions such as addiction, headaches, and even Parkinson's disease.
Some evidence also indicates that GABA may promote fat loss by stimulating the production of human growth hormone (HGH). HGH has the effect of building muscle, and normally decreases after a person reaches a certain age or stage of life. By promoting the continued production of HGH, GABA may counteract some of these effects of aging, and build strength and endurance throughout life. A standard dose for GABA supplementation is 200 mg three times a day.
