  • Uses For l-Theanine

    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.

    What Is The Source?

    l-Theanine is the most abundant free-form amino acid found in tea leaves. l-Theanine in supplement form is synthetically derived but is chemically identical to naturally occurring theanine. Hypo-allergenic plant fiber is derived from pine cellulose.
