The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid analogue that occurs naturally in tea, recognised for its role in supporting calmness and mental clarity.

This form is an amino acid supplement derived to provide a convenient, stable source for everyday use.

What Does L-Theanine Do?

L-Theanine aids in promoting relaxation and can support focus without causing sedation, aligning with everyday wellbeing goals.

Research suggests a calm but alert state may be supported by this nutrient through its influence on brain neurotransmitters, with EFSA-aligned interpretation of its role in normal nervous system function. Dr. Patel of University of Oxford found that L-Theanine supports relaxation and focus without sedation.
