Gaba Gaba Gaba What Does It Actually Do In The Brain

2-Minute Neuroscience: GABA

Gamma-Aminobutyric acid is the primary inhibitory neurotransmitter in the brain. It is the control knob of all control knobs. But why GABA? What, if anything, might be so special about the molecule?

To look at it, there is nothing inherently peculiar about the small four-carbon backbone structure of GABA. Solvation effects in solution allow GABA to take on five different possible conformations, some compact, and others more extended. At the receptor level, this flexibility means that GABA is a highly ‘druggable’ target. In other words, pharmaceutical analogs of GABA are more rigidly pocketable in select receptor subsets, and therefore potentially very specific.

If GABA itself is completely ordinary, does it, perhaps by chance, sit in some prized location within metabolism? Some of the apex positions in metabolic cycles are occupied by molecules like Acetyl-CoA and ATP. Acetyl-CoA sits right at the intersection of glycolysis, the TCA cycle, ketone production, -oxidation of lipids, and fatty acid elongation. It even plugs directly into synthesis of the neurotransmitter acetylcholine. Curiously, there are no major receptor systems associated with this complex molecule that might otherwise keynote its position inside the cell.

Is there any evidence that GABA signaling and metabolism are directly involved with nucleotide status?

Lifestyle Changes To Boost Gaba

There are also many ways to increase GABA without having to add in another supplement:

1. Exercise

Unlike endorphins that surge right after exercise, long-term physical activity has been shown to reduce stress and enhance GABA synthesis.

2. Meditation

According to research, GABA levels are higher in those who meditate. A consistent meditation practice also lowers cortisol which can inhibit GABA function.

3. Yoga

One study found that a single yoga session can increase GABA by 27 percent.

4. The ketogenic diet

High glutamate is associated with epilepsy and seizures which have been shown to be helped by a high-fat, moderate protein, low-carb, ketogenic diet. This diet can increase the GAD enzyme and uses ketones as a precursor to GABA. My book, Ketotarian, is all about a plant-based ketogenic diet.

What Is The Role Of Gaba In The Brain

Neurotransmitters, such as glutamate, acetylcholine, serotonin, dopamine, norepinephrine, and gamma-aminobutyric acid , in the brain are important for the transmission of signals between neurons. In particular, GABA is the major inhibitory neurotransmitter. This means that the role of GABA in the brain is to counteract the action of excitatory neurotransmitters such as acetylcholine, promote relaxation, and decrease brain activity. When GABA in the brain reaches levels that are below normal or when GABA action is impaired, the neurons become overexcited, leading to excessive muscle contraction and a sense of restlessness.

GABA in the brain has the highest concentrations in areas such as the hypothalamus, hippocampus, and cortex. Neurons are separated by minute spaces called synapses through which a command or a signal travels to reach the next neuron. The neurons are not physically connected therefore, GABA, as a brain neurotransmitter, acts like a molecular bridge. In particular, GABA binds to GABA receptors in the neurons plasma membrane, which results in the entry of chloride ions into the nerve cell or potassium ions out of the nerve cell. Approximately 30 to 40% of neural synapses have GABA.

Gabaergic Agents Directly Affect Antigen

GABA pathways in a normal human brain (Lundbeck institute ...

To further characterize the immune effect of GABA, we used several mechanisms of manipulating this endogenous GABA system in the immune system. GABAergic agents included muscimol, a GABA structural analog topiramate, a drug with GABA-A-R agonist activity and irreversible inhibitors of GABAT, vigabatrin and gabaculine, which decrease GABA degradation, thereby causing an effective increase in GABA concentrations . We also used the GABA-A-R inhibitor picrotoxin, which blocks the chloride channel .

To study the adaptive immune response, we tested these GABAergic agents using C57BL/6 mice transgenic for the myelin oligodendroglial protein T cell receptor , in which the vast majority of T cells respond to the MOG antigen. Naïve splenocytes of mice transgenic for the MOG TCR challenged in vitro with MOG 35-55 antigen proliferate and produce inflammatory cytokines. GABAergic agents added in vitro inhibit this effect in a dose-dependent manner . Affected cytokines included IL17 and IFN, primarily produced by T cells, and TNF, IL6, and IL10, which can be produced by either T cells or antigen-presenting cells , such as DCs and macrophages . There was no change in viability of splenocytes with treatment. These responses in unfractionated splenocytes could reflect a direct effect on either T cells or APCs or both.

    Does Gaba Have Risks And Side Effects

    Natural GABA is effective and doesnt have any side effects for most people.

    Rare side-effects that have been reported, especially at very high doses are:

    • Skin tingling, flushing or itching
    • Rapid heart rate
    • Difficulty breathing
    • Increase in anxiety and depression

    If you experience any of these side effects decrease our dosage and they should go away. Also consider discussing it with your doctor, especially if the symptoms persist.

    Do not take GABA if:

    • You are pregnant or breastfeeding
    • You are under the age of 18
    • You are on any prescribed medication for pain or that has an effect on the nervous system unless you have discussed it with your doctor, including opiates, anti-anxiety medications, sleeping tablets, and anti-depressants.

    Benefits Of Having Adequate Gaba In The Brain

    Having sufficient GABA in the brain will also aid in deeper sleep cycles as well as a decrease in blood pressure. Those who suffer from anxiety disorders can also benefit from taking GABAergic drugs. GABA is also useful for symptomatic relief of arthritic conditions and back pain, and can also be used as a regulator for muscle tone.

    Those who suffer from GABA deficiencies can take some GABA supplements in 200mg doses. There are GABA supplements in tablet and capsule form, and can be taken as much as 4 times a day or as your health care provider instructs you. There have been studies which show that GABA is generally incapable of crossing the blood brain barrier, but it is possible for it to enter the brain through spaces in the brain called ventricles.

    Taken orally, it has been said that GABA in the brain is able to increase growth hormone levels and prolactin due to it affecting the pituitary gland.

    Do I Need A Prescription

    No, you dont need a prescription to take GABA supplements. However, its always best to speak with your doctor before starting any new supplement regimen. Also, he or she can help make sure that it is the right choice for you and give you advice on taking supplements safely over time.

    GABA is an important neurotransmitter found in your brain that helps with many functions, like calming down and reducing stress levels. Its produced from Glutamate, which is an amino acid your body needs for energy and proper function. When you eat foods that are high in protein, your body produces more glutamate, which then helps produce GABA. GABA attaches to receptors on cells all over the brain and sends a signal telling it to calm down and relax. Its also responsible for keeping your heart rate stable and moderating stress levels. Yes, GABA is safe its been studied extensively and is effective and well-tolerated by people of all ages. The only side effect reported with it is drowsiness, so take it before bedtime if this happens to you.

    The Difference Between Types Of Neurotransmitters

    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.

    Why Do People Take Gaba Supplements

    GABAs natural calming effect on the brain has led to countless claims about the use of GABA supplements to reduce stress. Too much stress is linked to poor sleep, a weaker immune system, and a higher risk of depression, among other things. Heres a closer look at the effects of stress on your body.

    In addition, people with certain medical conditions may have lower levels of GABA. Some of these conditions include:

    • seizure disorders

    suggests that its only small amounts.

    Heres a look at some of the research behind GABAs more popular uses.

    With Gaba Theres An Entirely New Way To Look At Pleasure In The Brain

    Dopamine gets all the credit for being the brains official pleasure chemical, but theres a new horny neurotransmitter in town

    Despite the fact that sex is a basic instinct and a near-universal experience, we know remarkably little about it. And so, this week, were teaming up with our friends at Futurism, oracles of all things science, technology and medicine, to look at the past, present and future of pleasure from a completely scientific perspective.

    For a while now, the neurotransmitter dopamine has been seen as the conductor of good feelings. Its the subject of love songs, the seductress of biohackers and the ostensible pleasure chemical. But as research continues to uncover more about our brains reward system, dopamine is beginning to look less like the maestro and more like a member of the band.

    In a rodent study published over the summer, postdoctoral scholar Raaj Gowrishankar and his fellow researchers from the Bruchas Lab in Washington highlighted the contribution of GABA , a neurotransmitter that blocks impulses between nerve cells in the brain, to reward reinforcement as well. He tells me that it travels parallel to the same mesolimbic reward pathway that dopamine does, suggesting that its also involved in the generation of feelings like pleasure, motivation and anticipation.

    But as Gowrishankar emphasizes, its a big puzzle, and we only have a few of the pieces. One things for sure, though: Dopamine has more help than we thought.

    Gaba As A Food Supplement

    In recent years researchers have reported a number of placebo-controlled studies in which GABA was administered as a food supplement to healthy participants and participants with a history of acrophobia. One study found an increase in alpha waves in healthy participants and reduced levels of immunoglobulin A in participants with a history of acrophobia when they were exposed to heights . However, the sample size for the second finding was very small . Another study reported reduced heart rate variability and salivary chromogranin A during an arithmetic task compared to a control group after the administration of GABA-enriched chocolate . A third study reported less salivary cortisol and CgA than a control group during a psychological stress-inducing arithmetic task. Additionally, participants who received 50 mg of GABA dissolved in a beverage reported less psychological fatigue after completion of the task . Finally, in a fourth study, participants were found to show a decrease in alpha waves over time while performing an arithmetic task. This decrease was smaller in the group that orally received GABA compared to a control group . By way of comparison, one would have to eat 2.34 kg of uncooked spinach in order to consume a similar amount of GABA, and spinach is relatively rich in GABA compared to other foods .

    Are There Any Side Effects Of Too Much Gaba

    While GABA can offer many benefits, there are possible side effects while having too much of it.

    Potential side effects include numbness and tingling, especially in the extremities and mouth, drowsiness, nausea, lightheadedness, intoxication, hallucinations, and mood swings. It can also cause headaches or allergic reactions in some people.

    There are some other things to keep in mind before GABA supplementation. For example, alcohol and other sedative drugs can increase GABA activity leading to negative interactions.

    This can lead to respiratory depression and over-sedation. Therefore, be careful when taking GABA-modulating drugs.

    Some medications like benzodiazepines affect gamma-aminobutyric acid. Therefore, taking GABA with these drugs may increase the risk of overdosing.

    While medicine can reverse benzodiazepine intoxication, if it is not administered in time, the overdose could be fatal. If you experience any side effects, then you should decrease your dose to eliminate the negative feelings.

    Some medical conditions may also have adverse interactions with some GABA supplements, and you should take caution before choosing GABA as a supplement. For your safety, it is always best to have a doctor provide medical advice.

    Can Gaba Work For Anxiety And Stress

    We know that high levels of stress in modern living can cause a constant cascade of stress hormones such as cortisol and adrenalin.

    Often these stress responses are so intense that the body is unable to regulate itself naturally.

    High stress levels contribute to mental conditions such as anxiety, panic attacks, and depression.

    Stress has also been linked to many chronic conditions such as adrenal fatigue, fibromyalgia, diabetes, hypertension, heart attacks and strokes.

    Ive explained that GABA is the neurotransmitter responsible for calming down the nervous system.

    So why doesnt it work all the time?

    Under normal conditions, the excitatory and inhibitory systems work in harmony to keep the nervous system in balance.

    But when faced with chronic stress and fatigue, the neurotransmitters can get out of synch.

    The bodys natural stress response overpowers the amount of GABA that the body can produce to compensate.

    When we don’t have enough GABA, we can’t relax.

    Studies have found that when the action of GABA in the brain is compromised there could also be heightened physiological responses.

    These include high blood pressure, sweating, increased secretion of gastric acid and activity of the large intestine.

    We commonly associate these symptoms with too much stress.

    Im sure that you will agree that the obvious approach to stress and anxiety would be to increase the amount of GABA in the brain.

    What Causes Low Gaba Levels

    Learning About GABA Part 1

    While there is no direct cause of low gamma-aminobutyric acid, some factors contributing to low GABA are genetics, certain diseases, long-term stress, lack of exercise, and poor diet. Consequently, GABA deficiency can contribute to several other conditions.

    Some psychiatric conditions associated with low GABA include anxiety, depression, insomnia, and schizophrenia. Low GABA may also play a role in autism spectrum disorder .

    Some physical ailments of low amounts include pyridoxine deficiency, hepatic encephalopathy, Huntingtons disease, dystonia, and muscle spasticity. Frequent seizures may be another sign of too little GABA.

    Some of the common symptoms of low GABA include stress and anxiety, low mood, low energy, poor memory, difficulty concentrating, muscle pain, headaches, and insomnia.

    Low GABA may also contribute to substance use disorder and the abuse of substances. In fact, alcohol and some other common drugs of abuse influence GABA.

    You may also find that your symptoms get better when you try to increase GABA. There are several ways to increase GABA naturally that can be pretty effective for some people. While they may not all work, you may find one or two that have a beneficial effect.

    What Is Gaba Benefits And Functions In The Brain

    GABA is an essential neurotransmitter for a variety of functions, including sleep, stress, and cognition.

    GABA supplements are popular because low levels of GABA can contribute to anxiety, mood disorders, restlessness, and more.

    If this sounds like you, then you may naturally gravitate towards the thought of taking GABA supplements to improve your well-being.

    However, understanding this substance and how it works to provide many beneficial effects can help distinguish whether GABA is the problem or solution in your unique situation.

    Before we dive in, lets look at what GABA does, what is it, and why is it important?


      How Much Gaba Should I Take

      Natural GABA is non-toxic and should be safe for most people when taken at a proper dosage.

      I recommend that you begin with a lower dosage when you start taking a GABA supplement and then increase it gradually until you get the desired effect.

      The following dosages are recommended:

      General stress relief

      Take just before sleep. High dose ensures that more crosses the BBB
