Suntheanine is the premier, patented form of the amino acid L-theanine. Suntheanine is the purest form of L-theanine on the market today. L-Theanine is an amino acid derived from green tea that is responsible for the relaxation-inducing effect of tea consumption. Suntheanine has been shown to promote an alert state of relaxation. This is characterized by an increase in alpha brain waves (signifying a relaxed, alert state) and a decrease in beta brain waves (signifying an awake, excited state of mind).* Suntheanine may also improve sleep quality, enhance mental acuity and soothe away tension and nervousness.
- Promotes a relaxed state without drowsiness

iHerb Customer Reviews
This is one product your doctor will never tell you about. It is very good for mild insomnia, nervousness or anxiety. L-Theanine is an amino acid and should be taken on an empty stomach. It is a GABA precursor. GABA is a calming neurotransmitter. You can try to take GABA directly but it does not work on most people because it does not cross the blood brain barrier very well. L- theanine does. This is a trial size and worth getting to see if it works for you. The recommended dose by most sources is 100-200mg. This is 150mg and right in the middle. You may find you need a little more or less. You may find you need a 100mg size capsule to accommodate such dosing. It is a very good natural alternative to sleep and anxiety medications.

I love this stuff! Due to illness I wake up every few hours and cannot get back to sleep. I can take one of these every time I wake and get a few more hours sleep. I also like it to help calm me down. It is an amino acid so there is no chance of addiction and I spoke to the company and was told there is a cumulative effect when you take it every day. This is not a drug so you won't be hit in the face with the effects but I won't be without this stuff.
Very effective for stress & anxiety

I have been using theanine for years. I tapered off prescription medication for anxiety and went back to the trusty l-theanine. Shortly after I take this, I get a feeling of calm. It helps me sleep at night as needed. I also will take during the day during stressful times and it works well. I am a forever grateful for theanine.
Did not feel a difference, but this brand is good

Personally I did not feel a difference but I trust this brand. Things like L-Theanine are very different when it comes to effect on different people. It may work for you but I did not feel any difference. However I trust Dr. Best so I give this supplement a 5 star rating.
