Introduction

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.

Why GABA Is Important for Anxiety

Anxiety is often linked to an overexcited nervous system.

• GABA slows down overactive brain signals
• Reduces mental overstimulation
• Promotes calmness without sedation
• Supports emotional balance

GABA counterbalances excitatory neurotransmitters like glutamate.

• Reduces excessive neuronal firing
• Calms stress-related brain circuits
• Supports deeper relaxation and sleep
• Improves stress resilience
