Note: this is not a troll or me trying to be a jerk. Nonetheless, can you link us to some of the research on L-Theanine?

I used medical journals for the research, they are all behind paywalls -- if you have access to some University Journal Databases, check the sources in the bottom of the articles. The most recent study was published in December of 2010.
