High quality L-Theanine products. These products are an excellent way to provide your body with extra theanine on a daily basis. This amino acid occurs in tea leaves and of course tea itself. Green Tea contains a higher concentration Theanine than black tea. We sell L-Theanine, this is a more active and pure form of theanine, which is far better absorbed by the body and so more effective. The products we sell in our shop are way more highly concentrated than actual tea, because of this the effect of supplemental L=Theanine products is way more profound. These products are often used by fanatic sporters and sportive people. Also by people who have a natural or circumstantial high need for theanine. Besides these products we sell all other 20 amino acids which are natural in our body, in the form of great supplements from good brands.
