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.

iHerb Customer Reviews

Works good but I take 2-3 a day

Posted by iHerb Customer on Oct 12, 2017 | Verified Purchase

Lowers my heart rate and gives me a peace feeling without drowsy! But I need to buy the next mg. >up

Instant pleasure after taking it!

Posted by FibromyalgiaSpain on Aug 13, 2017 | Verified Purchase

I suffer Fibromyalgia, Fatigue Chronic Syndrome, CMS chemical Syndrome and EHS electrohipersensibility. Instantly after taking it I felt an instant hype. It helps a lot on stress and depression. Now it has become one of my 5 must with Sam-e, TMG, 5HTP and melatonine to sleep.

Not for my depression and anxiety

Posted by iHerb Customer on Aug 13, 2017 | Verified Purchase

It did not affect me, I did not feel any change to better for depression and anxiety

Thanks for your feedback!

It helps.

Posted by iHerb Customer on Jun 22, 2017 | Verified Purchase

It did help with my mood. But I would suggest taking 'breaks' from theanine. I took 2 pills/day for a month then two weeks off, and two weeks 1 pill/day. I believe these types of supplements are most beneficial when you set up your own schedule. Just listen to your body and do what feels right. I'd give it 4 stars, because I had theanine flush in the beginning, but it went away. That can be expected from theanine.

My natural valium.

Posted by grainfreeliving on May 21, 2017 | Verified Purchase

Natural valium in a bottle, this product is amazing. Will also calm my 10-year-old in the middle of an anxiety attack. I take before any event that normally would stress me out (social events, public speaking) and I just sail through. Highly recommend for anxiety.
