Product Description

Application of L-Theanine( Tea Extract): 

 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.
