What is GABA?
GABA stands for gamma-amino butyric acid ( Gamma-aminobutyric acid ), an important amino acid that plays a crucial role in the communication between neurons in our brain. It acts as a neurotransmitter that helps regulate various body and brain functions, including mood, anxiety and sleep.
The role of GABA in the brain
GABA is best known as an inhibitory neurotransmitter, meaning it reduces the activity of neurons. This helps to promote a sense of calm and relaxation, which is especially helpful in managing stress and anxiety.
GABA in dietary supplements
In addition to its natural presence in the body, GABA is also commonly found in various dietary supplements. These supplements are usually used to improve brain function and relieve symptoms of anxiety and insomnia.
Production of GABA Tea
GABA tea is produced by fermenting tea leaves in an oxygen-free environment, which increases the GABA content in the leaves. This process was first developed in Japan in the 1980s.
The origin in Japan
Production of GABA tea began in Japan, where researchers developed a method to increase GABA levels in tea leaves. This is done by placing the leaves in a sealed chamber and pumping nitrogen to displace oxygen.
The production process: Anaerobic fermentation
In this oxygen-free environment, the amino acid glutamic acid in the tea leaves is converted into GABA. After this anaerobic fermentation, the tea leaves are further processed and packaged, ready for consumption.
Health Benefits of GABA Tea
GABA tea is known for its multifaceted health benefits, ranging from reducing stress to improving sleep quality.
Stress Relief and Anxiety Reduction
GABA tea may help reduce stress and anxiety by increasing GABA levels in the brain. This can lead to a calming effect and improved mood.
Improving Sleep Quality
The inhibitory effect of GABA may also contribute to better sleep. Drinking GABA tea before bed can help you fall asleep and improve sleep quality.
Blood pressure regulation
Some studies suggest that GABA tea may help regulate blood pressure, which may be especially helpful for people with hypertension.
Side Effects and Precautions
While GABA tea is generally considered safe, there are some potential side effects and precautions to keep in mind.
Possible side effects
Excessive intake of GABA can lead to nausea, digestive problems and breathing difficulties. It is important not to exceed the recommended dosage.
see a doctor
If you have any medical conditions or are taking any medications, it is recommended that you consult a physician before using GABA tea or supplements.
