Front Neurosci · 2020 · Meta-analysis / systematic review
Effects of Oral Gamma-Aminobutyric Acid (GABA) Administration on Stress and Sleep in Humans: A Systematic Review

Conclusion: Fourteen studies met the criteria and were included in the systematic review. Although more studies are needed before any inferences can be made about the efficacy of oral GABA consumption on stress and sleep, results show that there is limited evidence for stress and very limited evidence for sleep benefits of oral GABA intake.

A Systematic Review of Plant-Derived Natural Compounds for Anxiety Disorders

Conclusion: Taking together, these phytochemicals may be considered as supplements to conventional anxiolytic therapies in order to improve efficacy and reduce adverse effects. Further preclinical and clinical studies are still needed in order to recognize the structure-activity relationships, metabolism, absorption, and neuropsychopharmacological mechanisms of plantderived natural agents.

“I can feel GABA despite the BBB claims. I don't take it often but When I do I know it...It just gives me a slightly uneasy tingling and kind of turns me into an asshole.”
