AddFocus™ utilizes GABA, a neurotransmitter that regulates activity of neurons to reduce anxiety, and increase cognitive enhancement. Addall is a supplement that can keep you focused for hours at a time.
Gamma aminobutyric acid (GABA) is a naturally occurring amino acid that works as a neurotransmitter in your brain. Neurotransmitters function as chemical messengers. GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system.
When GABA attaches to a protein in your brain known as a GABA receptor, it produces a calming effect. This can help with feelings of anxiety, stress, and fear. It may also help to prevent seizures.
As a result of these properties, GABA has also become a popular supplement in recent years. This is partly because it isn’t available from many food sources. The only foods that contain GABA are fermented ones, such as kimchi, miso, and tempeh.
Here’s a look at some of the research behind GABA’s more popular uses.
According to a 2006 article, two very small studies found that participants who took a GABA supplement had increased feelings of relaxation during a stressful event than those who took a placebo or L-theanine, another popular supplement. The article also notes that the relaxing effects were felt within an hour of taking the supplement.
High blood pressure
Some small, older studies have evaluated the use of GABA-containing products for lowering blood pressure.
In one study from 2003, daily consumption of a fermented milk product that contained GABA reduced blood pressure in people with slighted elevated blood pressure after two to four weeks. This was compared with a placebo.
A 2009 study found that taking a GABA-containing Chlorella supplement twice a day reduced blood pressure in those with borderline hypertension.
In a small 2018 study, participants who took 300 milligrams (mg)Trusted Source of GABA an hour before going to bed feel asleep faster than those taking a placebo. They also reported improved sleep quality four weeks after starting treatment.
Like many other studies looking at the effects of GABA supplements in humans, this study was very small, with only 40 participants.
Stress and fatigue
A 2011 study in Japan examined the effects of a beverage containing either 25 mg or 50 mg of GABA on 30 participants. Both beverages were linked to reduced measures of mental and physical fatigue while doing a problem-solving task. But the beverage containing 50 mg appeared to be slightly more effective.
Another study from 2009 found that eating chocolate containing 28 mg of GABA reduced stress in participants performing a problem-solving task. In another study, taking capsules containing 100 mg of GABA reduced measures of stress in people completing an experimental mental task.
The results of all of these studies sound promising. But most of these studies were very small and many are out of date. Larger, more long-term studies are needed to fully understand the benefits of GABA supplements.
