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 50 mg – 200 mg Suntheanine 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 of L-theanine. Suntheanine is not an extract of green tea but rather is produced via a patented process that mimics the natural process in green tea leaves, resulting in a 100% pure L-isomer-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|
|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.*
