Product Overview

Swanson Double Potency Suntheanine L-Theanine is a dietary supplement designed to help you achieve a state of calm alertness. Each veggie capsule delivers 200 mg of Suntheanine, a patented form of L-theanine, an amino acid naturally found in green tea. This supplement is ideal for individuals facing daily stressors who want to maintain focus and balance without feeling sedated.

Key Features and Benefits

  • Double Potency Formula: Each capsule contains 200 mg of Suntheanine, providing a higher dose for enhanced effects.
  • Promotes Relaxation and Focus: L-theanine supports alpha brain wave activity, which is associated with a relaxed yet alert state.
  • Non-Drowsy Calm: Unlike many calming agents, L-theanine does not cause drowsiness, making it suitable for use during work or study.
  • High Quality Suntheanine: Suntheanine is a clinically studied, pharmaceutical-grade L-theanine known for its purity and efficacy.
  • Vegan Friendly: The capsules are vegetable-based, suitable for vegans and vegetarians.
  • Convenient 60-Count Bottle: A one-month supply when taken as directed.

How to Use

Take one (1) veggie capsule daily with water, preferably with a meal or as directed by your healthcare provider. For best results, use consistently as part of your daily wellness routine. Do not exceed the recommended dose.

Who It Is For

This supplement is designed for stress-prone professionals, students, or anyone seeking to support mental calm and focus during demanding days. It is also suitable for individuals looking for a natural way to manage occasional stress without the side effects of traditional relaxants.

Why Choose This Product

Swanson is a trusted name in dietary supplements, known for quality and value. Suntheanine L-Theanine is backed by clinical research showing its ability to promote relaxation and improve attention.
