Theanine is a unique amino acid found almost exclusively in green tea that exerts beneficial effects on brain metabolism.* Theanine induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves.* Theanine may promote calmness by affecting dopamine and serotonin neurotransmitters in the brain.*

Jarrow Formulas^® Theanine Gummies incorporate theanine that is made enzymatically from amino acids and is identical to the theanine found in green tea.
