It has been shown to promote a ""relaxed, yet alert, feeling at rest"" (Owen et al., 2008).Evidence-based research has shown a variety of benefits from taking L-Theanine. It has been shown to have a calming effect when people are under physical and psychological stress, enhance attentional capacity and mental clarity, and improve overall cognitive performance. It has also been found that L-Theanine improves simple reaction time, speed of numeric working memory, word recognition, and accuracy of sentence verification.
