L-Theanine is a unique amino acid naturally found in green tea leaves, known for promoting relaxation without drowsiness. It has been extensively studied for its ability to improve focus, reduce stress, and enhance sleep quality by modulating brain neurotransmitters such as GABA, dopamine, and serotonin.
