Green tea catechins have shown a number of benefical effects, modern research and scientific data 

demonstrates that the beneficial effects of green tea are largely due to its main catechin, 

Epigallocatechin Gallate (EGCG). EGCG makes up about 30%-50% of the total catechin content 

and has an antioxidant activity about 25-100 times more potent than Vitamin C and E.The

L-Theanine is an analogue amino acid to the proteinogenic L-glutamate and L-glutamine, two of 

the twenty essential amino acids the body uses are precursors to protein synthesis. Once 

L-Theanine is ingested, it is absorbed into the bloodstream through the small intestines and is able 

to cross the blood-brain barrier intact, where it mediates an increase in levels of multiple 

neurotransmitters. Serotonin, dopamine, glycine, and gamma-aminobutyric acid (GABA) levels 

are all increased. Serotonin is central to regulation of mood, sleep, and learning. Dopamine is 

utilized extensively in the central nervous system and is implicated the the regulation of motivation, 

mood, and stabilization of muscle movements. Increased levels of glycine have been shown to 

improve sleep quality in humans, and has been used as an effective add-on treatment for 

schizophrenia. GABA is an inhibitory neurotransmitter that is shown to have a calming effect on 

mood when present in the brain and is also directly responsible for muscle tone.

Safety

There have been no reports of adverse effects caused by the consumption of Tea Polyphenols  

and Tea Polyphenols supplements.

Theanine has been approved for use in all foods in Japan, and is considered Generally Regarded as 

Safe (GRAS) by the FDA. Independent studies on mammals such as rats have also found that even 

extremely high doses of L-Theanine do not produce any negative physiological and psychological 

effects.

Dosage

Typical dietary doses of L-Theanine range from 200-250mg/day,however doses as high as 

1200mg/day can be used.
