Very Good product

Posted by NBPT10 on Oct 14, 2011 | Verified Purchase

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.

Great for sleep and anxiety. Won't be without it.

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.

Thanks for your feedback!

This veggie caps make me very happy. It is fall here now with darkness, this usually make me so sad. Now I am feeling happy, as happy as I am in summertime.

Theanine is important to me because I have a high stress job and getting older does'nt help. I'm a bus driver so the calming effect helps alot and it does'nt induce sleepiness which is good if you're driving.

Thanks for your feedback!

Good product. I am taking it before bed in order to sleep well and to be in a positive mood during autumn, winter time when it is lack of the sun.

Thanks for your feedback!

Feel the stress drift away.

Works great! I can feel my body relaxing only 10 minutes after taking one Doctor's Best Suntheanine L-Theanine 150mg cap. I have tried it for a few days now, and I am getting to sleep faster, and having a deeper restful sleep. I have never taken any medication for sleeping before as I usually sleep quite well, but my sleep patterns are off at bit these days. I do have an auto-immune disease, so I am being careful and watching for any unusual signs. I would recommend asking your doctor for sure about this first, because it works very well, and it may or may not be ok if you are taking certain other medication. Nighty night! :)

It works great !!

L-Theanine is used for pets in case of ecxessive barking, anxiety, fear, bad listening etc. When I buy L-Theanine for dogs in Holland it will cost me about 40 dollars a month ! I saved a lot of money buying Doctor's Best L-Theanine at iHerb. After 9 months of using I can get my dog's attention when she is barking, she listens better and has no fear of thunder, lightning and even fireworks anymore. She also has much more self-confidence. That's a result of training but without L-Theanine it was not possible to train. I'm very happy with the results and surprised it's so effective. Before using I did not believe it could work but I was wrong !! Feel free to visit my page (click on my name) for more reviews.

Works well!

Taking it in the evening it makes me sleep deeper than usual and I'm completely "down" waking up the next day. I take it as a stress fighter and to stay calm. Works very well!

Thanks for your feedback!

Supposed to be effective!

Posted by sweetheart on Jul 06, 2012 | Verified Purchase

I have used this for a couple of days only so I can't really tell yet if it's effective or not (that's why I'm giving it only 4 stars for now). However, L-theanine is supposed to be very effective since it's one of the few natural calming "medicines" that actually has been proven to be effective in various clinical studies. If you drink coffee, you should use this too to keep your cortisol (=stress hormone) levels down, especially if you tend to gain weight on your belly which can be a symptom of elevated cortisol. (Caffeine raises cortisol levels, L-Theanine is a natural antagonist to caffeine.)
