What is L-Theanine?
L-Theanine is a nonproteinogenic amino acid found abundantly in green tea leaves and certain mushrooms. It is one of the five umami components of green tea, contributing to its specific flavour [1]. L-Theanine is mainly known for its several health benefits, because of which it has become a valuable ingredient in the food and phracmeutical industries [1]. It can also be found in the form of L-Theanine gummies.
L-Theanine has a potent antioxidant-like activity and contributes to the savoury taste sensation called umami. Many studies have shown that this amino acid has several therapeutic effects, such as brain function, gastrointestinal function, cancer-drug therapeutic efficacies, antihypertensive effects, and immune function [2].
While L-Theanine was long known for its calming effects, scientific studies on its pharmacologic properties were initiated in part by this tradition. Animal neurochemistry studies demonstrate that L-Theanine increases brain serotonin, dopamine and GABA levels and has micromolar affinities with AMPA, Kainate and NMDA receptors [3].
