    Good products from a good company, but...

    I bought this version of L-theanine for my wife. She had run out of the same product, which she liked very much. Unfortunately, I made a mistake: this version contains gelatin. She said the tablets she had been taking did not contain gelatin. My fault; i should have checked more carefully. An expensive lesson.
