It is responsible for green tea's characteristic umami flavor and its calming, yet alert, effects. This bioactive compound is highly valued for its ability to promote relaxation, enhance cognitive function, and modulate stress responses.
“L-Theanine has been a cherished component of green tea in traditional Asian cultures for centuries, particularly in Japan and China. It was historically consumed to promote a state of calm alertness, enhancing meditation and intellectual pursuits, and is integral to the cultural significance of tea ceremonies.”Traditional Medicine
