How Green Tea Extract Works

The amino acid called L-theanine that is responsible for the unique taste that green tea has is also responsible for the calming effects found in the tea. Research shows that L theanine may shift brain wave activity from beta waves (that accompany anxiety) to alpha (that promotes relaxation). [2] L-theanine increases production of chemicals in the brain such as serotonin and dopamine which induce calmness. Though tea does contain caffeine, the amino acid is known to neutralize the effect. [3]

On the study mentioned above involving eight female university students, four ranked to have the highest anxiety and the other four the lowest anxiety were tested with 200 mg of L-theanine dissolved in 100 ml of water. The result was a generation of a high alpha wave emission which proves the relaxation effect of the amino acid. [4]
