The award-winning, patented dietary ingredient for stress and well-being
First introduced centuries ago, tea has become the most widely consumed beverage in the world, second only to water. Extensive research has been documented on tea, specifically green tea, for its many functional properties.
It has been estimated that nearly 65 percent of the adult population experiences some form of stress and these numbers are on a continual rise. Since ancient times, it has been said that drinking green tea induces relaxation. A pioneer in the science of green tea, Taiyo found this relaxation effect to be due to the presence of the amino acid L-theanine. Suntheanine® is the trade name for Taiyo's patented pure form L-theanine.
Biologically Active
Human clinical trials have shown Suntheanine® to promote an alert state of relaxation without drowsiness, as indicated by an increase in Alpha brain waves, and a decrease in Beta brain waves.
The brain emits weak electrical impulses that can be measured on the surface of the head, which are classified based on their frequency:
| Brain Wave |
Frequency (Hz) |
Mental Effect |
 |
| Delta |
0.5-3.0 |
Sound Sleep |
| Theta |
4.0-7.0 |
Dozing/Sleeping |
| Alpha |
8.0-13.0 |
Relaxed, Alert State |
| Beta |
14.0 |
Awake, Excited State |
Suntheanine® has been found to be most effective in the range of 50-200mg and its effects are exhibited within 30-40 minutes of consumption.
Additional human clinical research suggests that Suntheanine® may have application in improving the quality of sleep, diminishing normal symptoms of premenstrual syndrome (PMS), improving learning performance, heightening mental acuity, promoting concentration, reducing negative side effects of caffeine and supporting the immune system.
