About this ingredient
Ingredients
GABA (Gamma-Aminobutyric Acid) is a naturally occurring four-carbon, non-protein amino acid and an important inhibitory neurotransmitter in the central nervous system. It is involved in regulating neuronal activity through GABA receptors. GABA supplements may contain pure gamma-aminobutyric acid or specialized forms such as fermented GABA, depending on the manufacturer. The exact amount, source, form, and additional ingredients vary by product.
GABA (gamma-aminobutyric acid) is a naturally occurring compound that functions as the primary inhibitory neurotransmitter in the brain and a major inhibitory neurotransmitter in the spinal cord. GABA signaling helps regulate the activity of nerve cells by reducing the likelihood of excessive neuronal firing.
GABA is available as a dietary supplement in capsules, tablets, powders, and combination formulas. Some products contain standalone GABA, while others combine it with ingredients such as glycine, inositol, vitamins, or botanical extracts.
GABA supplements are commonly marketed for relaxation, sleep, stress support, and nervous-system wellness. However, the effects of oral GABA supplementation can vary, and research continues to examine how much orally consumed GABA reaches the brain because its ability to cross the blood-brain barrier is an important consideration.
Because dietary supplements can differ from products used in research and may interact with medications or other supplements, consumers should check the product label and consult a healthcare professional when appropriate.
