L-Theanine Usage:
1. Traditional/Ethnobotanical uses
Second only to water, tea is the most widely consumed beverage in the world. L-theanine was discovered 

as a constituent of green tea in 1949 and was approved in Japan in 1964 for unlimited use in all foods, 

including chocolates, softdrinks, and herb teas, except infant foods. It also provides a unique umami 

(brothy or savory) taste and flavor to green tea infusion.

2. General uses
L-theanine may help relieve stress by inducing a relaxing effect without drowsiness and may also 

possess immunologic attributes. Theanine may also have effects on the cardiovascular system and play 

a preventative role in cancer; however, limited clinical information is available to support these claims.
