  • Doctor's Best L-Theanine with Suntheanine supplement



  • Helps promote relaxation



  • Helps reduce stress and tension


Doctor's Best L-Theanine with Suntheanine supports relaxation without drowsiness to help manage stress and tension. Suntheanine is the premier, patented form of the amino acid L-theanine. Suntheanine is the purest form of L-theanine on the market today, derived from the amino acid in green tea that is responsible for the relaxation-inducing effect of tea consumption. Suntheanine has been shown to create an alert state of relaxation, and it may also support sleep quality and mental acuity.
