AlphaWave®  - L-Theanine

Second only to water, tea is the most widely consumed beverage in the world, appreciated for its calming and focusing effects. Research has revealed the amino acid L-Theanine, found in green tea leaves promotes a desirable state of alert relaxation. Human clinical trials have confirmed the ability of purified L-Theanine to increase the level of Alpha waves in the brain and enables a focused calm without drowsiness.

ENI’s AlphaWave® contains highly purified, GRAS-affirmed L-Theanine chemically identical to that found in green tea.

The Science Behind AlphaWave®:

New Clinical Study Confirms the Benefits of AlphaWave® L-Theanine

AlphaWave® is now supported by a new human study conducted at: The Wellington Sleep Investigation Centre, University of Otago, Wellington, New Zealand.

The Effects of AlphaWave® L-Theanine on Relaxation, Clarity and Cognitive  Function: a Human Study w/20 Subjects (Summary Report).

A randomized, double-blind, placebo controlled study with 20 subjects (performed at theWellington Sleep Investigation Centre, University of Otago, New Zealand), assessed relaxation through measurement of alpha brainwave changes and responses to stress tests. It also assessed changes in heart rate as indication of stress level. The dosage level used was 200mg of AlphaWave® L-Theanine or placebo.


AlphaWave® L-Theanine consumption produced significant changes over time as compared to placebo on all the variable outcomes assessed in this investigation. For example, AlphaWave® L-Theanine showed a positive effect over time on the tonic alpha power, that measures relaxed wakefulness, whereas the placebo had negative effects. Although the values for anxiety/tension were low, they decreased over time for both groups, and the decrease in AlphaWave® group was greater. The group consuming AlphaWave® also displayed reduced fatigue.

In addition, AlphaWave® L-Theanine significantly reduced the heart rate compared with placebo over the time period of the study. This was a further indication of the actual stress reduction effect of AlphaWave® L-Theanine.
