L-theanine is one of my favorite supplements. It is a tasty food with a unique umami savory taste which is pleasant and easy to mix in to beverage. The preferred form of l-theanine which is as a 100% powder than this doctor's best is the one to get.



Cons

I hate that celexa slows my thinking and short memory, but the anxiety is too much for me to handle. Gaba works much better for me. I like to be relaxed during the day but, in my case, theanine leaves me in a state of where is the * couch?

The product is 100% rice powder. The powder is expired/contaminated. There is a third ingredient that was not included in the picture or description on amazon here. The third ingredient is silicon dioxide.
