L-theanine is an amino acid found almost exclusively in tea plants and, in particular, green tea. The pioneers at Taiyo International discovered that the relaxing properties of green tea may be tied to this unique nutrient and developed Suntheanine® L-theanine through a patented process designed to amplify its calming potential. Research indicates that Suntheanine stimulates alpha wave activity in the brain, which is associated with calm alertness. Swanson Suntheanine L-Theanine delivers 200 mg per capsule, the upper limit shown to produce results in clinical research.

FAQ
- How does L-theanine work in the body?
L-theanine is an amino acid naturally found in tea leaves that supports brain health by promoting a calm, relaxed state. It influences brain signaling pathways involved in relaxation while supporting alertness and focus. - How does L-theanine support relaxation?
L-theanine supports relaxation by promoting a sense of calm without acting as a sedative. It helps the body manage everyday stress while supporting mental clarity and focus. - Will L-theanine make me feel drowsy?
L-theanine is not considered a sedative. Most people experience a greater sense of calm and relaxation without feeling sleepy, although individual responses may vary. - Why is L-theanine often paired with caffeine?
L-theanine and caffeine have complementary effects. While caffeine promotes alertness, L-theanine helps support calm focus, making the combination popular for enhancing concentration without the jittery feeling some people experience with caffeine alone. - When is the best time to take L-theanine?
L-theanine can be taken any time of day, depending on your wellness goals. Many people take it during the day to support calm focus or 30 to 60 minutes before bedtime to promote relaxation and support healthy sleep. - What is Suntheanine®?
Suntheanine® is a premium, patented form of L-theanine produced through a fermentation process that creates the same L-theanine found naturally in green tea. Suntheanine is known for its high purity, consistency, and quality, and has been the subject of numerous clinical studies. - Is Swanson Suntheanine® L-Theanine suitable for special diets?
Yes. Swanson Suntheanine® L-Theanine is suitable for vegan and vegetarian lifestyles, is made with non-GMO ingredients, and is formulated without gluten or dairy, making it a great choice for a variety of dietary preferences.
