Product Overview

  • Neurologically-Active Amino Acid
  • Promotes Relaxation
  • Supports Learning Ability
  • Suntheanine
  • Dietary Supplement

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 sensations of pleasure by affecting dopamine 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.

It works!

Posted by Reviewer2810860 on May 03, 2016

A family doctor who usually tries to heal with natural things first suggested this to my teen who had a few episodes with anxiety. We find that this does help when it is taken. The tricky part is getting a teen to remember to take it 3x/daily. I even tried it myself to see what she is experiencing and was pleasantly surprised to feel more calm and more able to focus at work. How cool it was to have a stressful situation at work and not appear stressed out. I hope others will give this a try before taking dangerous Rx's. 200mgs is what we purchased.

I have only bought one bottle of Jarrow Theanine... I do like Jarrow products.. I would like this much better if it did not have silicone dioxide in it. Pay attention to the other ingredient list on every product.
