L-theanine may help improve sleep when anxiety is a factor, but the specific evidence for this use is limited to just two positive studies.

            
            
            
    
                
                
  • 
                    
                    Both studies show positive effects, but the evidence base is small

                    L-theanine promotes relaxation by boosting alpha brain waves without causing drowsiness
