Relax with Suntheanine

The Only Clinically-Proven Form of L-Theanine!

L-Theanine is a special amino acid—the same found in green tea—that helps promote a restful, relaxed state while maintaining daytime alertness. L-Theanine is also scientifically shown to support healthy blood pressure levels that are already within normal range.

Take the edge off mounting stress, and relax naturally with L-Theanine!

Suggested Use

Recommendations: One capsule two or three times daily. If additional support is desired, increase to two capsules three times daily, or as directed by your healthcare practitioner.

Cellulose, vegetable capsule (modified cellulose), and magnesium stearate.

Contains no sugar, salt, yeast, wheat, gluten, corn, soy, dairy products, artificial coloring, artificial flavoring, preservatives, or ingredients of animal origin. This product contains natural ingredients; color variations are normal.

iHerb Customer Reviews

100mg too little for me, needed 5-6 pills a day to work

Posted by iHerb Customer on October 12 2017 | Verified Purchase

Not sure what to say here. Entirely subjective, but the 100mg dose is too little for me. Had some noticable positive experiences with 5-6 pills per day, but otherwise I'm not seeing any changes.

Thanks for your feedback!
