  • 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.

Rated 5 out of 5 by from It works. L-theanine is to help one relax and isn't meant to be a sleep aid, yet it does help me sleep well.

Rated 5 out of 5 by from Great for Relaxation Suntheanine L-Theanine is an excellent supplement for those who are stressed. The supplement works within 15-30 minutes of taking and returns one to a more relaxed state of mind and body (just like a good cup of hot tea). This product was the most effective of the supplements I have taken in reducing stress and has helped me during emotionally fragile times to relax and regain control.
