Product Overview

What is L Theanine?

L Theanine is an amino acid which can be found naturally in green tea.

Benefits of L Theanine

L Theanine is a naturally occurring amino acid that can be found in small quantities in a variety of foods. For maximum benefits however, it is necessary to supplement the diet with additional sources of L Theanine in order to enjoy its full effects. Although L Theanine is found in green tea it does not contain caffeine. L Theanine powder contains 100% L Theanine.
