What is L Theanine?

Before diving into the buying guide, let’s first understand what L Theanine is. It is an amino acid found in green tea leaves that has been scientifically proven to promote relaxation and reduce stress and anxiety.

Benefits of L Theanine Supplement

L Theanine supplements have numerous benefits which include:
