In terms of chemical structure, l-theanine is reminiscent of glutamine and gamma-aminobutyric acid. Though some people use theanine for these purposes, natural standard rates the evidence to support the usage for anxiety reduction, blood pressure control, and mood improvement as unclear or conflicting scientific evidence and the evidence for improved cognition as fair negative scientific evidence.

This may provide evidence of a link between l-theanine and the treatment of anxiety. This is not due to lack of research, because plenty of studies have been conducted and each and every one of them proved that l-theanin…
