The Science of Suntheanine

Biologically Active

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 WaveFrequency (Hz)Mental Effect
Delta0.5–3.0Sound Sleep
Alpha8.0–13.0Relaxed, Alert State
Beta> 14.0Awake, Excited State

Suntheanine has been found to be most effective in the range of 50 – 200 mg 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*.
