Product Overview

  • 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.

Great For Anxiety

This is great for Anxiety, I often open the cap and put it in my drinkbottle to sip on as I find the dose strong which I guess is a good thing! Good value for money I think and they have lasted me ages.

Very relaxing and anti-stressing and got better focus. This is helping me to defeat my social phobia. Helps me focus on conversations not my own doubts on my self.

Doing shift work i often dont get enough sleep, this does help me stay asleep for longer not as powerful as the PM variety ibuprofen but i feel a lot better on wakening.5 stars because of no side effects like a milk drink without the calories.
