What Is GABA?
GABA (short for gamma-aminobutyric acid) is an important neurotransmitter in the body. It is also available as a dietary supplement and supposedly provides several benefits, such as improving mood or promoting weight loss.
As an inhibitory neurotransmitter in the central nervous system, GABA usually decreases the chance that a nerve will "fire" and send out a signal. Although drugs that act like GABA or increase the levels are useful for a wide variety of medical conditions, such as epilepsy and anxiety, there is no strong evidence that taking GABA supplements will produce similar effects. In fact, there is little evidence to suggest that taking these supplements is effective for any use.
Although it is considered a "natural" substance, GABA may cause side effects such as an increase in heart rate or blood pressure. Also, this product may not be suitable for everyone, so make sure to talk to your healthcare provider before using these supplements if you have a chronic medical condition or if you are pregnant or breastfeeding.
