GABA—or gamma-aminobutyric acid—is the main inhibitory neurotransmitter in the brain, meaning that it prevents your nerve cells from firing an action potential (i.e. the body’s form of an electrical signal) (1). This makes it an exceptional amino acid for reducing stress and enhancing sleep.
In this article, you’ll learn the benefits of GABA, the signs of deficiency, the recommended GABA dosage for sleep, and the best GABA supplement for sleep.
