Source Naturals Serene Science L-Teanina, con Suntheanine®, 200 mg – 120 Cápsulas

What is L-Theanine?

L-theanine is a naturally occurring amino acid found primarily in green tea leaves. This unique component is known for its ability to promote a state of relaxation without causing drowsiness. In Source Naturals Serene Science L-Theanine, the patented form Suntheanine® is used, backed by studies suggesting its effectiveness in supporting mental calm and concentration.

Benefits of L-Theanine

L-theanine can contribute to various aspects of mental and emotional well-being. According to available evidence, its benefits include:

• Support for relaxation without drowsiness: Helps reduce feelings of occasional stress and promotes a state of calm without affecting alertness.
• Improved concentration: Can promote sustained attention and mental focus, especially in situations requiring cognitive performance.
• Reduction of nervous tension: May help alleviate mild symptoms of anxiety and nervousness, according to some studies.
• Sleep quality: Although it does not cause sleepiness, it can contribute to more restful sleep by reducing mental activation before bedtime.

These effects are based on the action of L-theanine on brain neurotransmitters, such as GABA, serotonin, and dopamine.

How does L-Theanine work in the brain?

L-theanine crosses the blood-brain barrier and modulates the activity of several neurotransmitters. It has been shown to increase alpha brain waves, which are associated with a relaxed alert state. Additionally, it can increase levels of GABA, an inhibitory neurotransmitter that promotes calmness, and modulate serotonin and dopamine, which influences mood and motivation. This unique mechanism of action allows for the benefits of relaxation without the typical sedative effects of other compounds.
