GABA, or Gamma-aminobutyric acid, is a non-protein amino acid that calms the nervous system, promoting relaxation and downgrading anxiety. GABA may also improve mood, help with PMS symptoms, treat ADHD, reduce blood pressure, and play a role in synthesizing melatonin, the sleep hormone.

GABA naturally occurs in the brain, and we’ve used a synthetic form in Calmful Sleep.
