What is GABA?

Gamma aminobutyric acid (GABA) is a natural active non-protein amino acid.

  • GABA exists widely in nature, including the mammalian nervous system, botanicals such as tomatoes, grapes, potatoes, pumpkin, and tea, as well as fermented foods such as kimchi, germinated brown rice and pickles, which are also rich in GABA.
  • GABA plays a fundamental role in the regulation of the life activities of the organism.
  • GABA is an important neurotransmitter widely distributed throughout the central nervous system. It serves as a critical calming agent for the body, helping to combat stress and anxiety.
  • Having enough GABA in our body is a guarantee of feeling relaxed and happy. Lack of GABA will lead to tense feelings, fear and sleep problems.

Even though GABA can’t cross the blood-brain barrier (BBB), it can still affect your brain. The enteric nervous system (ENS) is the network of neurons that controls your gastrointestinal system. The ENS not only contains many GABA receptors but also GABA itself and is connected to the brain via the vagus nerve. Therefore, oral GABA can even affect the brain without passing the BBB through its interaction with the ENS.


Certain studies show the health benefits of GABA for improving the focus, relaxing the body, relieving fatigue and improving sleep. It is therefore scientifically very well founded. A study with Gabarelax™ shows that it has a beneficial effect on stress and sleep disorders.

A few studies with GABA


Relax and anti-stress


GABA is the most important inhibitory neurotransmitter in the brain, which helps prevent nerve cells from firing too often. Over-firing can cause restless, irritability and anxiety. As such, GABA has a calming and soothing effect.


Improving mental focus

GABA can promote mental focus with feelings of calmness. GABA can also increase glucose phosphatase activity, dilate blood vessels to increase blood flow and reduce blood ammonia, so that vigorous activity of the brain cells can promote the metabolism of the brain tissue, restore function of brain cells, improve brain activity, and enhance memory.


Relieving fatigue


GABA plays an important role in brain functions. It not only regulates cardiovascular and pituitary functions but also modulates renal function. Several studies have reported the effects of GABA on relaxation and fatigue reduction.
