GABA (or gamma-Aminobutyric acid) refers to a neurotransmitter that regulates and inhibits certain activities in our brain. In recent years, consumer demand for GABA products is increasing and supplements are popping up in health food stores everywhere. GABA is an invaluable nutritional supplement for body builders, power lifters, runners, martial artists, and athletes of all types as it increases lean body mass. GABA also has significant calming and soothing effects, as such it has been found to lower blood pressure, control hypoglycaemia, prevent anxiety and promote restful sleep. With all this fanfare, little attention has been paid to GABA tea - an all natural source of GABA.
