Swanson GABA is a dietary supplement with 500mg of gamma-Aminobutyric acid (GABA) in a capsule. It functions as an inhibitory neurotransmitter that has a calming and relaxing effect, reduces fear and improves sleep quality and regeneration.

GABA (γ-Aminobutyric acid) - one of the most important neurotransmitters in the central nervous system (CNS), where it inhibits the activity of the nervous system. It is a compound that belongs to the group of amino acids; it is created from glutamine in the presence of vitamin B6. It reduces psychophysical tension, lowers excitability, has a relaxing effect on skeletal muscles, prevents the restless legs syndrome. It does so by activating specific membrane receptors (GABA receptors), which are divided into two types: GABAA receptors (responsible for inhibiting neurotransmission in the nervous system) and GABAB receptors (responsible for inhibiting the synthesis of neurotransmitters). Type A receptors, present in nearly every neuron, are the place where many compounds called the agonists of receptor GABA are active. In that category are included, among other substances: alcohol, GHB and benzodiazepines - popular drugs which reduce fear and have a calming and sleep inducing effect; often used recreationally, with time they cause a physical and psychological addiction.

Why is GABA good for sportspeople?
Cortisol and growth hormone (GH) are hormones that even an unexperienced beginner in sports is familiar with. The former, called the stress hormone, evokes rather negative associations, as, on the one hand, it has a catabolic effect on muscle tissue (it causes muscle protein degradation), and on the other hand, it stimulates the development of fat tissue (particularly with a negative relation with insulin), mostly in places such as the face, the neck and the waist. On the contrary, growth hormone is the one that supports muscle development, stimulates fat tissue degradation (lipolysis) and is responsible for organism regeneration. GABA enables reaching top performance exactly through reducing the level of cortisol and increasing the concentration of growth hormone. Activating GABA receptors inhibits the release of the corticotrophin-releasing hormone (CRH) in the hypothalamus, thanks to which it reduces the production of adrenocorticotropic hormone (ACTH) by the pituitary gland - the direct stimulator of cortisol production by the adrenal cortex. At the same time, GABA stimulates the release of somatotropin (growth hormone) from the pituitary gland, supporting the development of an athletic silhouette.

To sum up, Swanson GABA is a dietary supplement that supports reaching a good form by reducing the level of cortisol and increasing the level of growth hormone. It has a calming and relaxing effect, supports regeneration and improves sleep quality. It is recommended for people who live in permanent stress, suffer from insomnia, feel anxiety or fear, as well as for sportspeople who aim at a muscular, athletic silhouette.
