Green tea, prepared from the Camellia sinensis plant, has been consumed since ancient times for its calming influence. Modern research has looked into this “ancient wisdom” and revealed that L-theanine, an amino acid found almost exclusively in green tea, has specific and positive effects on the brain and nervous system, especially the promotion of relaxation without drowsiness. L-theanine is a naturally stirring non-proteomic amino acid found almost solely in tea plants, and it’s the main component responsible for the exotic taste called “umami” of green tea. L-Theanine is also responsible for producing the feeling of relaxation after drinking of green tea. It is also known to support the neurological function and brain activities.
