L-Theanine is a relaxing but non-sedating amino acid. This product by Now Foods featuring Suntheanine which is an award-winning patented brand of L-Theanine from Japan. I like this great product a lot. It’s like yoga in a bottle because it helps to bring me back into balance with my nervous systems. Unlike other stress reducing supplements, Suntheanine does not cause drowsiness. Suntheanine brings a state of clarity into my day which can help me make better life decisions. I highly recommend this high quality product. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects. I hope you'll find my review Helpful to you. Best wishes and good health to everyone!

Heard this would help with my sleep. They did not help me.

Although I like the Now Foods brand I think that this product is a miss. I find that I need to take multiple capsules at once to accomplish the desired effect and find the Green Tea extract unnecessary at best if not even hard for digestion. Will try the patented Suntheanine formula next time.

I have IBS and this thing doesn't do good with my tummy. I haven't had even a chance to take it for a good period of time to test it's effectiveness of calming, because of this side effect. So if you have a sensitive digestive system, consider this carefully.
