GABA is a naturally occurring amino acid in the brain that
plays a critical role in regulating the human central nervous system. It is linked with calming and
soothing the body and increasing muscle tone. As we age, GABA levels in the
brain decrease. In fact, unless you take an artificially manufactured dietary
supplement, tea is the most efficient way to get GABA in your diet. This
powerful amino acid boosts alpha wave activity in our brains, which promotes a
state of relaxed concentration. Think "quiet alertness."
