GABA is technically known as gamma aminobutyric acid, a naturally occurring amino acid found throughout the body
Called a neurotransmitter, GABA works as a chemical messenger that slows down activity in the brain and central nervous system
GABA benefits include its ability to help support relaxation and a calm mental state to prepare you for sleep
Magnesium can increase GABA levels in the body
If you’ve read recent articles about the GABA-sleep connection or seen ads for GABA sleep aids, your first thought might be, “What does GABA stand for?” While the scientific name gamma aminobutyric acid might not roll off your tongue, you might know it more commonly as GABA.
But what is GABA and what is GABA used for? Read on to learn more about GABA health benefits and the connection between GABA and sleep.
What is GABA?
While GABA is found throughout the body, the pancreas’ insulin-producing beta-cells make GABA.  What does GABA do in the brain? As an amino acid, GABA works in the brain as a chemical messenger that carries signals throughout the body. What is the main function of GABA? It slows down nerve system activity, inhibits certain brain signals, and plays a key role in helping support a calm & relaxed mental state. 
As mentioned above, GABA produces a calming effect in the brain, and therefore may help with feelings of stress and prepare you for sleep. Does GABA make you sleep? GABA helps facilitate sleep by calming and relaxing the mind. Its ability to slow down nervous system activity impacts both the mind and the body. How? It supports relaxation and a calm mental state to prepare you for sleep. 
Does GABA help you relax? Yes, GABA does that, too! As noted above, the GABA-stress connection comes from slowing down or blocking neural activity, which helps support a calm mental state.  In other words, GABA helps to "put the brakes on" an overactive mind because it inhibits or slows down certain brain signals, producing a calming effect on the brain. Although additional research is needed, several smaller studies showed GABA’s stress-reducing abilities. 
What Does Too Little GABA Do?
Low levels of GABA are often associated with undesirable effects.  For instance, low GABA levels can lead to difficulty concentrating, headaches, and other sleep problems, memory issues, and muscle pain.  Depleted levels of the neurotransmitters glutamate and GABA are commonly associated with some disorders, but these levels return to normal when mental health is improved. 
How Can You Maintain Healthy GABA Levels?
Besides being produced in the body, some foods contain GABA including barley, beans, broccoli, fermented foods (such as yogurt and tempeh), kale, mushrooms, oats, peas, rice, spinach, sweet potatoes, tea, tomatoes, and wheat. [3,4]
You can also help maintain a healthy GABA level by increasing your magnesium intake, either through food or supplements. Magnesium is involved in hundreds of processes in the body, including helping relax the body to prepare you for sleep. Magnesium can actually raise GABA levels, which promotes relaxation as well as sleep.  Magnesium-rich foods include dairy products (such as yogurt and milk), green leafy vegetables, legumes, nuts, seeds, whole grains, and fortified breakfast cereals.  Another option? Taking a magnesium supplement.
As a naturally occurring amino acid, GABA works as a neurotransmitter or chemical messenger in the brain. Its primary function is to lower activity in the brain and central nervous system. GABA uses include promoting relaxation and a calm mental state to prepare you for sleep. Magnesium can increase GABA in the body, so it helps to eat magnesium-rich foods such as milk, nuts, seeds, and whole grains.
