GABA tea is tea fermented under nitrogen gas (anaerobic conditions), which converts glutamate to GABA. Contains 150-300mg GABA per 200mL cup. Japanese studies show it reduces blood pressure by 8-10 mmHg after 2 weeks of daily consumption. The GABA content is confirmed analytically and the BP-lowering effect is consistent. Also known as Gabaron or 'stress-relief tea.' NOT the same as supplemental GABA capsules — the tea matrix may enhance delivery. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
