Suntheanine® is a high-purity, L-isomer form of the amino acid theanine (>98% pure L-Theanine). Suntheanine® is not an extract of green tea but rather is produced via a patented fermentation process that mimics the natural process in green tea leaves resulting in the L-isomer form of L-Theanine. It’s clean, reliable and clinically proven (the subject of 200+ scientific and clinical studies). Suntheanine® is protected by over 40 U.S. and international patents for its various physiological benefits and L-isomer-specific production processes and has long been trusted by consumers all over the world.

Suntheanine® has been recognized as one of the most effective ingredients for stress, relaxation and improved quality of sleep. Suntheanine® has also been studied for its benefits on immune health, managing metabolic syndrome, ADHD and has been found to pair well with CBD/Cannabidiol. Its effects can be felt in as little as 30 – 60 minutes.

When taken during the day, Suntheanine® improves alertness, focus and concentration (without drowsiness). If taken before bedtime, Suntheanine® does not act as a typical sleep aid (which often make people feel groggy and tired in the morning), but rather promotes a more restful quality sleep so you can feel refreshed and rejuvenated in the morning.

    Technical Details & Test Data

    Scientific Studies

    Mechanism of Action:

    • The science of Suntheanine® L-theanine has been well-studied and well-established. L-theanine is a derivative of glutamic acid, a significant and important neurotransmitter found in the brain.
    • L-theanine is fat-soluble and is readily absorbed in the intestinal brush-border membrane and crosses the blood-brain barrier via the leucine-preferential transport system.
    • L-theanine absorption results in increased dopamine and GABA levels in the brain, and an increase in Alpha brain waves and decrease in Beta brain waves.
    • This promotes an alert state of relaxation without drowsiness.

    Clinical Studies:

    Suntheanine® has been the subject of over 200 clinical and scientific studies and has been studied extensively in safety and toxicity studies. In most of these studies, the Suntheanine® form of L‐theanine was used, and not generic alternatives. In human clinical trials, Suntheanine® has been shown to promote an alert state of relaxation without drowsiness, as indicated by an increase in Alpha brain waves, and a decrease in Beta brain waves. These brain effects promote the use of Suntheanine® for:

    • Stress
    • Sleep
    • Energy
    • Cognition & Memory
    • Relaxation & Calming
    • PMS
    • Immune Health
    • ADHD

    Suntheanine® has also been extensively studied in animals and is used for similar health benefits in animals as in humans (treating behavior problems in cats and dogs).
