L-Theanine (gamma-ethylamino-L-glutamic acid) is a non protein forming amino acid found in trace amounts in green tea. It converts in the brain into GABA, the neurotransmitter involved in inhibiting over active mental activities, such as stress, anxiety, worrying, and nervousness. Unlike sedating herbs theanine protects & enhances cognition, without causing sleepy or drowsiness. Also unlike other GABA compounds like Phenibut there is no withdrawal effect.
