About
GABA (gamma-aminobutyric acid) is the brain's primary inhibitory neurotransmitter responsible for reducing neuronal excitability. While oral GABA's ability to cross the blood-brain barrier is debated, some research suggests it may support relaxation through peripheral nervous system pathways.
How It Works
Primary inhibitory neurotransmitter; oral GABA may act on peripheral/enteric nervous system to reduce arousal.
