GABA Tea

Posted on

GABA is an amino acid that is produced by the human body. GABA stands for Gamma-aminobutyric acid. Its main function is to inhibit the firing of neurons in the brain. Because of this inhibitory function, GABA sends messages to the brain, spinal cord, heart, lungs, and kidneys to slow down. 
GABA tea is an all-natural source of GABA. It was discovered more than 20 years ago by Japanese researchers looking for a natural method to preserve food. They discovered that tea which is oxidized in a nitrogen-rich atmosphere has a higher concentration of GABA elements than any other type of tea.  
GABA tea production involves exposing fresh tea leaves to nitrogen instead of oxygen. The fresh tea is placed in stainless steel vacuum drums and the oxygen is deprived and replaced with nitrogen. The tea leaves are exposed to this nitrogen-rich atmosphere for about 8 hours. The temperature must be kept above 40 degrees Celsius for the duration of the processing. This procedure produces the highest concentrations of natural GABA.
