🌿 L-Theanine

Premium Amino Acid for Relaxation, Focus, Mental Performance & Sleep Wellness

Product Description

L-Theanine is a naturally occurring amino acid best known as a characteristic component of tea leaves (Camellia sinensis). It is widely used in modern nutritional supplements designed to support relaxation, mental focus, cognitive performance and evening wellbeing.

Unlike conventional sedating ingredients, L-Theanine has attracted particular interest for promoting a relaxed yet attentive state, making it suitable for both daytime focus formulations and evening relaxation blends.

Clinical studies have investigated L-Theanine in relation to stress responses, attention, cognitive performance and sleep quality, both alone and in combination with caffeine.

🔬 Clinical Research Highlights

🧠 Stress & Relaxation

Human studies have investigated L-Theanine's effects on subjective stress, physiological stress responses and relaxation. Research suggests it may influence brain signalling associated with a relaxed mental state, although results vary between studies.

🎯 Focus & Cognitive Performance

Randomised controlled studies have investigated combinations of L-Theanine and caffeine and reported effects on aspects of attention, alertness and task performance.

🌙 Sleep Quality

Clinical studies have also investigated L-Theanine in relation to sleep quality and relaxation before sleep. Importantly, L-Theanine isn't generally considered a conventional sedative; its sleep positioning is better focused on relaxation and sleep quality.

🧬 Brain Activity

Research using EEG measurements has investigated L-Theanine's relationship with alpha-wave activity, a pattern commonly associated with relaxed wakefulness and attentive relaxation.
