of L-theanine enhances brain alpha-wave activity, a sign of relaxation. The intensity of brain alpha-wave activity increases within 30-45 minutes of L-theanine supplementation, resulting in enhanced relaxation and improved mental focus and acuity. This effect is most pronounced in
persons subjectively feeling the highest levels of distress. A small Japanese study of university students showed 200 mg oral L-theanine led to increased brain alpha-waves and a subjective sense of relaxation. Theanine administration caused a dose-dependent relaxed, yet alert, state of mind without sedation, beginning approximately 40 minutes after oral dosing. L-theanine enhances production of dopamine and serotonin and appears to play a role in the formation of GABA – a neurotransmitter that acts like a “brake” during times of runaway distress. Theanine helps establish balance in the neurotransmitter system, resulting in improvements in the mental/emotional and physical disturbances resulting from chronic stress.
In vitro and animal studies demonstrate L-theanine has an antitumor effect and potentiates the effect of some chemotherapeutic agents. L-theanine also inhibits LDL oxidation. An animal study demonstrated a dosedependent hypotensive effect of L-theanine. Conditions that may respond
positively to L-theanine supplementation include anxiety, stress, insomnia, and hypertension. In addition, it has been shown to increase the activity of the chemotherapy drugs doxorubicin, idarubicin, pirarubicin, cisplatin, and irinotecan.
