Gamma-aminobutyric acid GABA is a neurotransmitter, or chemical messenger, in the brain. It blocks specific als in the central nervous system, slowing down the brain. This provides a protective and calming effect on the brain and body. The body produces GABA, and it may also be present in some fermented foods, such as kimchi, miso, and tempeh.
These are not foods that most people include in their daily diets, so some people take GABA supplements to achieve the benefits. In this article, we examine how increased levels of GABA may impact the brain and body, and whether taking GABA supplements could have the same benefits. The brain contains many neurotransmitters that trigger or inhibit specific reactions in the body.
This activity produces effects such as:. The brain naturally releases GABA at the end of a day to promote sleepiness and allow a person to rest. Some of the medications doctors prescribe to induce sleep and reduce anxiety may also increase the action of GABA. Some experts have suggested that increased levels of GABA may have benefits, but the evidence is not clear.
According to a review , GABA has anti-microbial, anti-seizure, and antioxidant properties and may help treat and prevent conditions such as:. Doctors may prescribe medicines that increase the amount of GABA or stimulate the same neurotransmitters in the brain to treat some medical conditions, such as epilepsy. According to one study , people who have depression may have reduced GABA levels in the brain.
The use of benzodiazepines may be beneficial in those instances. Doctors also prescribe the medication gabapentin Neurontin , which is chemically similar to GABA to reduce seizures and muscle pain. However, doctors are not clear whether the therapeutic effects of these medications are related to their effect on GABA receptors or whether they work in other ways. Manufacturers may add GABA to:. However, the FDA do not regulate dietary supplements in the same way as medications.
Therefore, consumers should exercise caution as to where they purchase the product from and only buy from reputable vendors and companies. Some people may take a supplement in pill form, while others may add it to foods, such as protein drinks. Researchers have not established a daily recommended intake or a suggested upper limit for GABA. Anyone wanting to take GABA as a supplement should consider talking to their doctor first. At present, there is not enough research to evaluate the possible side effects of taking GABA supplements.
However, if a person does experience side effects that might be GABA-related, they should discontinue the use of the supplement and contact their doctor. Some researchers have voiced concerns about the supposed positive benefits of taking GABA supplements. An article in the journal Frontiers in Psychology notes that experts remain unclear whether GABA offers real benefits or whether the effects that people report experiencing are a placebo response. Other researchers do not believe that GABA supplements cross the blood-brain barrier, which they would have to do to have any effect on the body.
Although the study was small, involving just 30 healthy volunteers, it showed how GABA supplementation might promote enhanced thinking. An older study from found that taking mg of GABA daily helped reduce stress due to mental tasks. Like many other studies related to GABA, the study was small and involved just 63 participants. A research study asked 21 healthy males to take a supplement with whey protein or whey protein plus GABA once a day for 12 weeks. The participants performed the same resistance training exercises twice a week, and the researchers measured the . The researchers found that the combination of whey protein and GABA increased levels of growth hormone compared to whey protein alone.
Although this was another small study, the researchers concluded that GABA supplements might help to build muscle and assist in workout recovery. They recommended that researchers conduct more studies. GABA naturally plays an essential role in promoting sleep, relieving anxiety, and protecting the brain.
Scientists have not been able to prove the positive effects of GABA supplementation on a large scale, and their use may have limited effectiveness. If a person has received a diagnosis for conditions such as depression, anxiety, or attention deficit hyperactivity disorder, they may wish to talk to their doctor about medically-proven treatment before taking GABA supplements.
