Gamma-Aminobutyric acid (GABA): An informative, detailed overview


Gamma-Aminobutyric acid (GABA): An informative, detailed overview

GABA is an inhibitory neurotransmitter in the central nervous system. It is responsible for reducing neural excitability.

Mood disorders, epilepsy and chronic pain are consequences of low GABA levels in the body. GABA can also be found as a supplement in the market.

GABA supplements can help enhance sleep quality, provide a relaxing effect and improve anxiety management.

It can also help reduce blood pressure, alleviate PMS syndrome, improve mental focus and lower the chance of obesity.

Is GABA in foods?

Although GABA cannot be found in nature, plenty of foods can affect the way GABA works in the brain.

The foods such as fruits, vegetables, tea, and red vine have positive effects on it.

How does GABA work?

GABA inhibits certain signals sent to the brain as a neurotransmitter and decreases nervous-system activity.

The amino acid GABA inhibits the excessive firing of neurons in the brain by attaching to a protein known as the GABA receptor, resulting in reduced brain excitability.

6 Health benefits of GABA

As a supplement, GABA is usually known as an anti-anxiety remedy. Also, many people use it to get rid of inflammation issues.

Here, there are some of the essential benefits of GABA:

GABA can improve calming effect

By inhibiting neural activity and reducing brain excitability, GABA can reduce stress, ease anxiety and improve calming effect.

As a natural relaxant, GABA can improve mood by promoting calming effect.

GABA can enhance sleep quality

It seems that low GABA levels correlate with sleep problems such as insomnia and disrupted sleep.

GABA can induce sleep and create calmness by reducing stress and easing anxiety.

Researchers believe that taking it 30 minutes before sleep can make the best result.

GABA can reduce blood pressure

Many studies have shown that GABA can reduce blood pressure in people who suffer from hypertension.

Therefore it can reduce the risk of heart attacks, strokes, and heart failure which are linked to high blood pressure.

GABA can improve brain function

GABA can improve focus and concentration by reducing anxiety, fighting depression, and balancing mood disorders.

Also, many studies have found a correlation between GABA in specific brain areas and IQ.

GABA can lower the chance of obesity

Obesity is one of the most widespread health conditions. It can increase the risk of heart disease and osteoarthritis.

Based on a newly released study by Korean researchers, GABA can reduce fat and triglyceride levels and increase lean muscle mass.

GABA can alleviate PMS syndrome

Based on many pieces of research, it seems GABA levels decline during the menstrual cycle in women.

Therefore, as the off signal for neurons, a lower amount of GABA will hardly damp down anxiety and thus, lead to losing the ability to relax.


Generally, there is no reported side effect of GABA.

But it seems to be safe if you are pregnant or breastfeeding.

Bottom line

GABA is an inhibitory neurotransmitter in the brain that cannot be found naturally in food.

It inhibits certain signals sent to the brain and decreases nervous-system activity. It can be taken to

  • Reduce anxiety and improve the calming effect
  • Enhance sleep quality
  • Reduce blood pressure in people who suffer from hypertension.
  • Improve brain function
  • Can lower the chance of obesity
  • Alleviate PMS syndrome
