Very effective for stress & anxiety

Posted by PurpleHeart on Jan 25, 2016

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.

Haven't really noticed any "calming" ...

... effect when taking these, so I can't really recommend these to anyone. The effect is very mild at best. PS. Be sure to check my profile page for +180 reviews on iHerb products.

Наверно слишком мало, чтобы судить об эффекте

It works great !!

Posted by OrganicGirl on May 23, 2013

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.
