GABA Green Tea

GABA green tea is a slightly fermented green tea that contains a higher amount of GABA (Gamma Amino Butyric Acid) than regular tea (about 150ml or more GABA in 100g of tea).

All green tea naturally contains a relatively small amount of GABA (about 30ml in 100g of tea). However, in 1987, the Japanese Tea Research Institute succeeded in increasing the GABA level in tea by using a special manufacturing process. Since then, it has been studied for its ability to help us relax and help us lower our blood pressure. Positive results made it popular as a healthy tea.

What is GABA?

GABA naturally resides in the human body's central nervous system, such as the brain and spinal cord, and acts as an inhibitory neurotransmitter that suppresses excitement.

It is a type of amino acid that maintains blood pressure and sympathetic nerves in their normal state, suppresses and lowers blood pressure spikes, relieves tension and stress, and calms brain excitement, thus improving the quality of sleep. 

History of GABA tea

About 40 years ago, in an effort to improve tea farming techniques, the Tea Industry Research Institute was examining whether it would be possible to preserve fresh leaves for a long period of time while still maintaining its fresh flavor. After numerous experiments, they found that the GABA in the tea was significantly increased when raw tea leaves were stored in a container with a concentration of nitrogen gas, which is also used to preserve fruits such as apples. 

Why GABA tea?

GABA is a natural constituent of of grains, vegetables and fruits, and it is not an additive. Many of us ingest GABA on a daily basis without even realizing it. In recent years, supplements and functional foods containing GABA have become available. However, GABA tea is recommended for those who want to naturally incorporate GABA into their diets, and for those who have problems with high blood pressure, body fat, and stress. Additionally, our GABA tea offers not only GABA, but all of tea’s other health benefits. 

Meet the Producers: Organic GABA Green Tea

Meet Ikezaki-san and Mizuno-san. They are the owners of The Craft Farm and are producing our Organic GABA Green Tea. They left their previous jobs to head out into the countryside. They saw that there are abandoned tea plantations and almost no young people in the surrounding area. This realization shocked them and encouraged them to work so that the Japanese tea industry would not die. They had the thought, "We must not let the fading light go out." Their new home was an over 100-year-old house deep in the mountains and, leading somewhat of an austere life, they were able to improve their living environment little by little. They have a deep desire to protect the tea fields and connect the lives of the local community. This is what calls them to make tea today. It is their belief that tea can heal the minds and bodies of people today as it has done for Japanese folks of the past. We're happy to support such bright, young people who are so enthusiastic about tea.
