What is gaba

As convenient as it would be to be in total control of our mood, the truth is, our mental state is governed in large part by a unique cocktail of neurotransmitter chemicals in the brain—one of which is GABA gamma-aminobutyric acid. GABA is essentially your body's "calm down" signal, pumping the brakes on overexcited neurons, contributing to an overall relaxing effect. However, various lifestyle and genetic factors can throw GABA out of whack, leading to serious disruptions in physical and mental health.

GABA is the main inhibitory neurotransmitter produced in the body. That means it blocks certain signals in the central nervous system to counter the excessive neural "excitement" that can lead to mental and physical health problems. GABA works in conjunction with another neurotransmitter called glutamate to maintain overall balance.

Think of GABA and glutamate as the yin and yang of the brain. When GABA-receptor binding occurs, it triggers the release of compounds such as peptides and chemokines that can quell hyperexcitability of brain cells, explains Ilene Ruhoy, M. Why that's important: "Depending on the area of the brain involved, hyperexcitability of the neurons can manifest as seizures, headaches, muscle cramping, anxiety, insomnia, tics, or psychiatric disorders," says Ruhoy.

Normally, excess glutamate is automatically converted to GABA by the body to keep you on an even keel i. But a variety of factors can cause imbalances in these two neurotransmitters, resulting in poor GABA activity in the body. According to Ruhoy, these factors include genetics, along with environmental stressors, poor diet, poor sleep, excessive heat or cold exposure, medications especially antibiotics , lack of exercise, and gut disorders.

Abnormally low GABA levels have been implicated in a number of undesirable life-disrupting conditions and disorders. The good news: Research reveals that when you optimize GABA levels and activity, you support mood, focus, sleep, and more. Although most of the research examines the effects of GABA supplementation on various health outcomes, you can also optimize GABA levels via lifestyle changes outlined in detail in the following section.

Breus, Ph. In a recent study , participants who took mg of a natural form of GABA PharmaGABA before bed fell asleep faster and had better quality sleep after one week of supplementation. Additionally, supplementation with magnesium, which is a GABA agonist i.

Given GABA's role in balancing out the excitatory effects of glutamine, it's thought that it also helps to keep feelings of stress in check this is why many anti-anxiety drugs target GABA-A receptors. In one small study , researchers had participants consume either distilled water, distilled water with L-theanine a calming compound in green tea , or distilled water with a natural form of GABA PharmaGABA.

Sixty minutes later, they measured their brain waves with an electroencephalogram EEG test and found that GABA significantly increased participants' alpha brainwaves which are typically generated in a relaxed state and decreased beta brainwaves typically seen in stressful situations compared to L-theanine or water.

In another experiment conducted by the same researchers, participants with a fear of heights received either a placebo or mg GABA in the form of PharmaGABA before walking across a suspension bridge over a canyon. Salivary levels of the antibody immunoglobulin-A sIgA —which is associated with relaxation at higher levels—were measured at various stages.

The placebo group experienced a significant drop in sIgA, while the GABA group's levels remained stable and even increased slightly by the end, indicating that they remained more relaxed. Research demonstrates that GABA can have a positive influence on an individual's ability to perform mental tasks that require significant concentration and relieve both the psychological and physical fatigue that typically impair this concentration.

In one small study , participants several of whom had chronic fatigue were given a beverage containing either 0, 25, or 50 mg of GABA and then asked to perform a difficult math problem. Researchers found that those in the two GABA groups experienced a significant reduction in psychological and physical fatigue, as measured by reductions in certain biomarkers including cortisol. Preliminary research suggests GABA can promote healthy blood pressure, at least according to a few lab studies.

Understanding just how effective GABA might be for supporting healthy blood pressure will require more robust research, but one early study found that daily supplementation with 80 mg of GABA had a positive effect on blood pressure in adults.

In many cases, we can do quite a bit with supplementation, diet, and lifestyle to optimize GABA levels, says Ruhoy, including "eating the right diet free of processed foods, exercising, calming our minds, meditating, breathwork, and more.

Many studies regarding GABA's effects on health outcomes have been done using supplements because they're easy to control and administer. Of these studies, several have utilized PharmaGABA, which is a naturally sourced form of GABA, produced via a fermentation process that uses the same bacterial strain Lactobacillus hilgardii used to make kimchi.

Ruhoy explains that "patients do experience a response" with supplements and that "a few studies suggest [they] do cross the blood-brain barrier. Research has shown that it is magnesium's effect on GABA-A receptors, specifically, that elicit this calming effect. Foods naturally rich in magnesium include cooked greens, salmon, dark chocolate, kefir, black beans, avocado, and a variety of nuts and seeds. When shopping for a supplement, Vora prefers magnesium glycinate , which has been shown in studies to help combat insomnia.

Additional ways of improving GABAergic activity include movement and meditation. In a new study , patients with clinical depression were assigned to do yoga two to three times a week. After 12 weeks, researchers found that this yoga practice increased levels of GABA on a temporary basis, and suggested that taking one yoga class weekly might help maintain those enhanced levels. Another study found that people who meditated for a minute session experienced a significant increase in something called a cortical silent period CSP in the brain, which is basically a period of reduced neuron activity in the brain caused by GABA.

Additionally, research on animals suggests that long-term exercise enhances the brain's capacity to synthesize GABA, at least in certain brain regions. Diet is crucial for maintaining healthy GABA levels and activity for a number of reasons. For one, a poor diet can drive inflammation, putting an excessive burden on your body that impairing your ability to make and use GABA.

So, in terms of eating to optimize GABA, passing on processed fare and consuming a variety of nutrient-rich, minimally processed foods think a Mediterranean diet is a great place to start. Glucose ideally from complex carbohydrates or dark chocolate and B vitamins from a variety of veggies, whole grains, legumes are also important GABA precursors, she adds. Per a research review , here are some of the best dietary sources of GABA that you can start layering into your overall anti-inflammatory diet:.

Additionally, Ruhoy recommends consuming fermented foods, as certain bacteria in fermented foods also synthesize GABA. These include:. Of course, consult with your doctor before starting a new herbal supplement, especially since they may interact with other medications you're taking.

Clearly, taking steps to optimize GABA via diet and lifestyle changes is a smart and safe way to promote overall health. Manufacturers don't recommend this supplement if you're pregnant or breastfeeding or for children under 6 years old. This is a common dose recommended by supplement manufacturers, though some people choose to go higher, says Ruhoy. If you're unsure about the appropriate dose for the symptoms you're dealing with, consult with your doctor or an integrative or functional medicine expert who's well-versed in dietary supplements.

It's clear that GABA, your body's main inhibitory neurotransmitter, is key for physical and mental well-being. And while optimizing GABA with diet, exercise, and stress-busting practices like meditation can help, research is increasingly suggesting that naturally derived supplements including magnesium glycinate and PharmaGABA may deliver that extra boost you need, particularly if you're dealing with something like anxiety or insomnia.
