Green tea has been recognized for centuries as having relaxant properties. L-theanine, a unique amino acid derived from tea, is the biologically active constituent of green tea responsible for its characteristic taste and for promoting both alertness and relaxation in people.
This amino acid blend promotes relaxation and helps to moderate occasional stress, nervous tension, and irritability without causing drowsiness. Preliminary research suggests that L-theanine may also be helpful for premenstrual support, including healthy mood and relief from tension.
For many people, L-theanine works rapidly after administration or consumption.
Research indicates that L-theanine could even be beneficial for a good night’s sleep. Administration of 200 mg of L-theanine was found to reduce resting heart rate, underlining its ability to promote relaxation. Researchers found that doses of 250 mg and 400 mg of L-theanine improved sleep in humans.
Theanine can also be useful for supporting healthy cellular function and for nervous system support.
Relaxation Support: Preliminary clinical evidence shows an increase in alpha brain wave activity after theanine administration. Alpha waves are an indication of an alert/relaxed mental state.
Premenstrual Support: In a clinical test, theanine provided both mental and physical support for women, including moderation of occasional irritability and stress.
Nervous System Support: L-theanine moderates the effects of caffeine on the central nervous system. It has also been shown to support healthy neurotransmitter function.
L-Theanine’s safety is supported in studies and by its long history of safe consumption in tea.
