Research shows that GABA tea (GABA an acronym for gamma-Aminobutyric acid) was created in Japan and refers to tea that has undergone an oxygen-free fermentation process. Once fermented this way the tea leaves accumulated and stored GABA.
Starting in 1984 Tojiro Tsushida and his collaborators from the then MAFF National Research Institute of Tea (now the National Institute of Vegetables and Tea Science) successfully produced a new type of tea where all the glutamic acid had been converted to GABA without changing the catechin or caffeine content.
Through fermenting green tea for 6 to 10 hours in an oxygen-free environment (instead Nitrogen was used) they found that GABA accumulated in the tea leaves.
The experiment was then rolled out to include oolong and black tea and the same result occurred in so far as the accumulation of GABA was concerned.
Outside of the chemical processes involved to produce this GABA rich product, the recorded benefits have been identified as follows:
- Reduction in hypertension
- Improved sleep
- Lowering blood pressure
- Among many other benefits.
