Product Information



Theanine 100 Neurologically-Active Amino Acid
Promote Relaxing*
Supports Learning Ability*
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 improve learning ability and serotonin neurotransmitters in the brain.* Also, theanine exerts protective effects on the brain by mitigating glutamate toxicity.*
Jarrow Formulas ® Theanine is made enzymatically from amino acids and is identical to the theanine found in green tea.
