GABA is the brain's primary calming neurotransmitter. It plays a critical role in reducing anxiety, calming racing thoughts, and preventing overstimulation of the nervous system.
When GABA activity is low, the brain remains in a constant "on" state, which can lead to anxiety, restlessness, poor sleep, and stress sensitivity.
This guide explains how GABA works, who may benefit from it, and how it can support anxiety relief naturally.
What Is GABA?
GABA (Gamma-Aminobutyric Acid) is a neurotransmitter that inhibits excessive nerve activity in the brain.
It acts as the nervous system's natural brake, helping the mind and body shift from a stressed state to a relaxed one.
