Customer Reviews
Review by MeMe
What I've read about L-Theanine is true. Has helped me alot and within minutes of taking it. Not the best taste in the world, kind of an odd sweet taste, but ok enough to just put the 1/8t on my tounge and drink something to wash it down. it does not disolve well in beverages so that's why I started just putting it on my tounge. Really helped my focus and being able to concentrate as well as producing a very calming effect even though I did not feel any type of anxiety. I'd think it would work well for someone who has anxiety, but of course this is something you want to discuss with our Dr. Appears to be a high quality product, and as always I received my order very quickly! :o) Very Pleased as always!
