History and Usage: L-Theanine (5-N-ethylglutamine) is a unique free-form amino acid found in green tea. L-Theanine is the predominant amino acid in green tea and makes up 50% of the total free amino acids in the plant. L-Theanine is a relaxant that increases alpha-waves producing mental and physical relaxation decreasing stress and anxiety, without inducing drowsiness. L-Theanine is a building block for gamma amino butyric acid (GABA). GABA blocks the release of the neurotransmitters dopamine and serotonin, playing a key role in the relaxation effect.
