L-Theanine is a unique amino acid found almost exclusively in the tea plant and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that l-theanine crosses the blood barrier, increases and GABA levels in the brain, and inhibits the stimulatory properties of caffeine. Human studies have shown that taking l-theanine results in the emission of brain waves associated with a state of relaxation.
