What is Suntheanine?
It has been estimated that nearly 65 percent of the adult population experiences some form of stress, and these numbers are continually rising. 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, found almost exclusively in tea. Clinical research suggests that 50mg - 200 mg Suntheanine naturally stimulates activity in the brain known as alpha waves, which are associated with a relaxed but alert mental state. Suntheanine is the trade name for Taiyo's patented, pure form L-theanine.
How does it work?
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 |
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.*
Is it safe?
Suntheanine has been shown to be safe based on numerous favorable toxicology and efficacy studies. Unlike other stress reducing supplements, Suntheanine does not cause drowsiness. Suntheanine has been consumed in beverages, foods and supplements since 1994 with no indication of adverse reactions or contraindications. The GRAS Affirmation (Generally Recognized as Safe) of Suntheanine received confirmation from the US FDA in 2007 for its use in a number of food and beverage categories (GRN 000209).
Award Winning, Patented Technology
Suntheanine was awarded the "Food Ingredient Research Award" at the 1998 Food Ingredients Europe and "Best New Product of 2000" at Nutracon. Suntheanine is protected by over 40 U.S. and international patents for its various physiological efficacies and L-isomer specific production processes
