L-Theanine Powder

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.
