γ-aminobutyric acid · main CNS inhibitory neurotransmitter · PharmaGABA natural Lactobacillus hilgardii fermentation canon. Abdou 2024 stress alpha-waves +18%, Yamatsu cortisol −20%, BP reduction 7/4 mmHg meta. 100-500 mg pre-stress/sleep.
4GABA appears in 4 protocols personalizable→γ-aminobutyric acid · main inhibitory neurotransmitter of the adult CNS · synthesized from glutamate via GAD (glutamate decarboxylase) with Vit B6 (P5P) cofactor.
GABA (γ-aminobutyric acid) is the main inhibitory neurotransmitter of the adult CNS (~40% inhibitory brain synapses). Endogenously synthesized from glutamate via GAD (glutamate decarboxylase) with mandatory Vit B6 (P5P) cofactor. Acts on GABA-A receptors (ionotropic Cl-) and GABA-B (metabotropic). Modulates anxiety, sleep, muscle tone, blood pressure, neuropathic pain.
Supplementation: historic controversy about BBB crossing · oral GABA mol wt≈103 + zwitterion charge limits conventional BBB passage. But PharmaGABA (natural fermentation Lactobacillus hilgardii Pharma Foods Japan patent) shows clinical systemic effects via: vagus afferent nerve (peripheral enterocyte GABA receptors → CNS vagal modulation) + possible partial BBB crossing in pathology (BBB altered in chronic stress). Mechanisms: Abdou 2024 EEG: PharmaGABA 100 mg → alpha-waves +18% within 60 min (relaxed state), beta-waves −22% (excessive alert state). Yamatsu 2024 acute cortisol stress: PharmaGABA 100 mg pre-stress → cortisol −20%, VAS anxiety scale −33%. Inoue 2024 hypertension meta: PharmaGABA 80 mg × 12 wk → BP −7/−4 mmHg in pre-hypertensives. Yamatsu insomnia: 100-300 mg pre-sleep → sleep onset latency −38%. NOT benzodiazepine action (not direct GABA-A α1 · not agonist) · subtle indirect effect. Differentiate from GHB / phenibut (not recommended · dependence).
