I have written 200+ articles in health and medicine and looked into L-Theanine specifically.

It has benefits and does work to enhance the benefits of caffeine. That said, this article over-hypes it, and it's really not that big of an impact.

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?

the wikipedia article seem to be much more useful and objective than the original post http://en.wikipedia.org/wiki/Theanine ,and see references there-in

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.
