It turns out that L-theanine could speed up your reaction time so you can think and respond faster. A study asked participants to complete a series of tests before and after taking L-theanine. The tests measured reaction time through visual attentional tasks and audio response tests. Not only did they perform better on tests after taking L-theanine, but they also felt calmer and less anxious.
