Product Overview

Natural Factors Stress-Relax Suntheanine L-Theanine offers a clinically studied dose of 125 mg per capsule, harnessing the power of Suntheanine—the world's most researched form of L-theanine. L-theanine is an amino acid naturally found in green tea, known for its ability to promote a state of calm alertness. This non-drowsy formula helps you manage stress, improve focus, and support a relaxed mood without sedation.

  • Stress Support: Helps reduce stress and anxiety by increasing alpha brain waves associated with a relaxed state.
  • Improved Focus: Enhances concentration and cognitive performance, especially during stressful tasks.
  • Pure and Potent: Free from artificial additives, gluten, and GMOs. Manufactured in a GMP-certified facility.
