GABA and Relaxation: What This Calming Messenger Does and How to Support It

Your brain's natural brake pedal.

Quick answer

GABA (gamma-aminobutyric acid) is the brain's main inhibitory neurotransmitter. It acts like a brake pedal, calming nerve activity and balancing the brain's excitatory signals. Healthy GABA activity supports relaxation, a calm mood and restful sleep. Ways to support GABA naturally include regular exercise, yoga and meditation, slow breathing, good sleep habits and foods such as fermented foods, green tea and whole grains. Some studies suggest GABA supplements may support relaxation and sleep quality. GABA may add to the effects of sedative medicines, so check with your doctor.

Key takeaways

If your mind races at night or feels constantly on edge, your brain's calming system may need some support.
