Conclusão

Research consistently suggests that GABA-related supplements may help you fall asleep faster, though most evidence comes from animal studies rather than human trials.

  • All 16 studies show positive effects on sleep onset
  • A GABA and L-theanine combination was shown to decrease sleep latency in one study
  • GABAergic pathways are central to the brain's natural sleep-initiation process
  • Most studies are preclinical — more human trials are needed to confirm benefits
