Description

L-Theanine is an amino acid which is a deriviative of glutamine. It is commonly found in tea and can produce a feeling of relaxation and anxiolysis. 

L-Theanine produces these effects by increasing the level of gamma-aminobutyric acid production. L-Theanine affects the levels of serotonin and 

dopamine in the brain. It also inhibits glutamic acid excitotoxicity.

to over 9 m in height and is pruned from 60 cm to 1.5 m for cultivation. Its dark green, serrated-edged leaves are alternate and oval, while its white 

and fragrant blossoms appear singly or in clusters.

Theanine Application

 

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.

 

 

Theanine Recommended Dosage


Data supporting a clinical role for theanine are weak. Studies reporting an anti-anxiety effect used single doses of theanine 200 to 250 mg.
