All teas contain modest amounts of GABA (gamma-aminobutyric acid) however GABA teas can contain up to fifty times more of the inhibitory neurotransmitter than in conventional teas. This is achieved via a special vacuum-fermentation process where the harvested leaves are put into tanks that are pumped with nitrogen to create the anaerobic conditions needed to enhance the process of converting glutamic acid in the leaves to GABA, while also creating the distinct GABA tea flavour.
