Why is L-theanine so soothing?

Studies show L-theanine can cross the brain-blood barrier, positively affecting the brain’s pathways associated with mental relaxation and calmness. It can significantly increase brain wave activity that helps promote a state of wakeful rest similar to meditating. L-theanine also helps decrease glutamate signaling, effectively calming the mind—even during those go-go-go days.

Action-packed days demand a lot from our bodies. Over time, the unmanaged stress can leave us feeling frazzled.1 For many, drinking a freshly brewed cup of green tea has been the best way to achieve a state of “zen,” even when life is hectic. That’s because green tea is rich in L-theanine, a naturally occurring amino acid that has been shown to support a healthy response to stress.2
