GABA tea is a relatively new type of tea with some health benefits. The main ingredient is gamma-aminobutyric acid (GABA) – an amino acid that occurs naturally in the human body. GABA is the main inhibitory neurotransmitter found in the nervous system and also in the retina.
Taiwanese GABA tea is an all natural product. It is made from high-grade whole-leaf that is naturally rich in glutamic acid – the precursor to GABA. GABA tea is produced according to standards set by the Japanese government, and meets or exceeds the Japanese standard of 150 mg of GABA per 100 grams of tea. The processing involves exposing the fresh tea leaves to nitrogen gas under controlled conditions.
