GABA Tea: The Complete FAQ

Gaba Tea is one of the richest food sources available for natural GABA (Gamma-aminobutyric acid) – an important amino acid that functions as a neurotransmitter in the central nervous system. We, at the Espirita Tea company, are proud to be your best source for organic, medicinal grade Gaba Tea.

1. So what's the deal with GABA tea in a nut shell?

Without getting into the science, GABA is an acronym (gama-Aminobutyric acid) for a key inhibitory neurotransmitter that is responsible for some great health benefits. One of the reasons we love tea is that GABA naturally accumulates in small quantities in green tea and Oolong, approximately 5-10mg per cup. We’re talking your everyday cup of grocery store bought green or Oolong tea is packing some GABA goodness. However, “regular” tea loses most of it’s GABA during the processing of the final product.

2. How much GABA content is in GABA tea?

For a tea to be considered a “GABA tea” it must have at least 150mg of GABA per cup.

3. How is GABA tea produced?

GABA tea has a special oxygen-free fermentation step added to retain the GABA content in the tea leaf, before it becomes the final dry leaf product.

4. Who is accredited with being the Father of GABA Tea?

This technology was created by Dr. Tsushida in Japan in 1984 and today there are GABA tea producers throughout Taiwan, China and Japan.

5. What's the Science Behind GABA Tea?

In 1984 at the MAFF National Research Institute of Tea, Dr. Tsushida and his team were successful in produced GABA-rich tea which managed to captured GABA without altering the content of caffeine or catechin. The key was the discovery of a new process of tea fermentation, in which nitrogren flushing was used in a vacuum canister for 6 to 10 hours to create anaerobic fermentation conditions. The leaves treated in this oxygen-free environment was found to accumulate high concentrations of GABA content in green tea, oolong tea and even in black tea.

6. What Health Benefits Does GABA Tea Boast?

Labatory synthesized GABA has been proven in clinical trials to be effective treatment for hypertension. In the 80’s, promising data compiled in the 80’s in Taiwan showing that GABA reduces blood pressure in animal and humans. Today GABA tea is a popular and effective medium for adding GABA into our diets and many have reported GABA tea helping with:

– Memory and Alertness

– Focus and Studying

– Aids weight loss

– Stabilizes blood pressure

– Improves sleep and relaxation

– Help with depression and anxiety

The Science

The GABA Molecule (gamma-Aminobutyric acid)

Gamma-aminobutyric acid, or GABA, is a neurotransmitter that sends chemical messages through the brain and the nervous system, and is involved in regulating communication between brain cells.

The role of GABA is to inhibit or reduce the activity of the neurons or nerve cells.

GABA plays an important role in behavior, cognition, and the body’s response to stress.

Research suggests that GABA helps to control fear and anxiety when neurons become overexcited.

Lower-than-normal levels of GABA in the brain have been linked to schizophrenia, depression, anxiety, and sleep disorders.
