What is gaba used for

It plays a role in how people experience anxiety, fear, and stress. GABA acts to slow or block certain nerve signals in the brain, sometimes reducing feelings of anxiety.

Without the right level of GABA activity in the body, nerve cells can be activated in ways that exacerbate certain conditions, like anxiety disorders. Neurotransmitters are chemical messengers in the nervous system. GABA is a non-protein amino acid that functions as an inhibitory neurotransmitter throughout the central nervous system. It limits nerve transmission by preventing the stimulation of neurons. GABA reduces a neuron's tendency to produce an action potential neuron stimulation , making neurons less likely to excite nearby neurons.

Misfiring in GABA signaling is associated with certain neurologic and psychiatric conditions. Inhibitory neurotransmitters like GABA block certain brain signals and decrease nervous system activity.

Another inhibitory neurotransmitter, serotonin, helps stabilize mood. Excitatory neurotransmitters have the opposite effect: They promote certain brain signals and increase nervous system activity. An example of an excitatory neurotransmitter is norepinephrine. Unlike excitatory neurons, which promote excitatory nerve action potentials, inhibitory neurons make neurons less likely to fire. When an action potential arrives at the axon terminal of a gabaminergic neuron and causes the release of GABA into the synaptic cleft, the following occurs:.

GABA activates receptors within milliseconds, and its concentration declines within milliseconds. But the effect lasts longer than that because GABA unbinds from its receptor relatively slowly. In the brain , GABA activity has a calming effect. In the spinal cord , this process allows for sensory information integration and helps to create smooth movements. It is understood that decreased action of GABA can contribute to mental health conditions. Appropriate GABA activity promotes a healthy stress response by preventing excess neuronal excitation.

Many things can impact GABA levels and associated receptor functioning, potentially contributing to anxiety. For example, it's been documented that external stressors and early life stressors can directly influence GABA receptor functioning, creating imbalances.

GABA deficits are associated with cognitive deficits, and this has clinical significance for people who have schizophrenia. Problems with GABA membrane transporters and receptors, namely a lack of adequately functioning GABA-A receptors, have been associated with certain clinical features of schizophrenia, including hallucinations and cognitive impairment.

This has opened avenues for understanding how GABA modulation might provide therapeutic benefits to people with schizophrenia. While the exact pathology of autism spectrum disorder ASD is still unclear, animal and human studies have found associations between abnormalities in excitatory glutamate and inhibitory GABA neurotransmitter functioning and underlying ASD symptoms, including deficits in restricted interests and social reciprocity.

GABA likely works in collaboration with other neurotransmitters, such as serotonin, which is also involved in mood disorders.

It has been suggested that improper GABA functioning may also be one of the factors that has a role in suicide. Outside of mental health, GABA is also involved in several disease states:.

While GABA is considered the most ubiquitous inhibitory neurotransmitter, it does not work alone. Research suggests that dysfunction of GABA and other neurotransmitters, namely serotonin 5-HT and corticotrophin releasing hormone CRH , play a role in depressive disorders. Medications that act on GABA receptors are of clinical significance in the treatment of a variety of disorders.

Drugs that modulate GABA signaling include:. GABA is available in non-prescription supplement form. Manufacturers sell natural GABA in pills and capsules at a range of prices, claiming their products can help reduce stress, induce feelings of calmness, and promote temporary relaxation. It can be found as an isolate or blended with other substances like melatonin, which promotes sleep. The manufacturers of gabapentin were found to have been marketing it extensively for off-label uses like the treatment of bipolar disorder, restless leg syndrome, hot flashes and stopping smoking.

While off-label prescribing is not uncommon, and usually fairly safe , there is no evidence that gabapentin is effective for the bipolar disorder it was being prescribed to treat or some of the other conditions for which it's being prescribed. Presently gabapentin is again making headlines as its use as a recreational drug skyrockets.

Many opioid users are misusing gabapentin to extend opioid highs or bypass drugs that block opioids effects, but its status as a non-controlled substance makes it difficult for law enforcement to control its unsanctioned use. Why not just give patients GABA? We have a highly selective membrane that keeps our blood and cerebrospinal fluid or brain juice, if you will separate: the blood-brain barrier BBB.

This membrane also contains special channels to diffuse important molecules one way or the other, like glucose. Upon entry to the brain, heroin is converted into morphine , which is why heroin is so much more potent than morphine. The evidence seems all but clear until you throw a few more studies into the mix.

Why the disagreement? Well, a few things. In mice it was found that GABA was removed from the brain 17 times faster than it entered. This could explain the conflicting study results. The enteric nervous system ENS is the network of neurons that control your gastrointestinal system. 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 results. 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.
