The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid naturally found in tea that supports relaxation and a calm mental state without sedation.

In this complex, it is presented as a single active ingredient that contributes to balanced neurological function as part of a multi-ingredient formulation.

What Does L-Theanine Do?

L-Theanine plays a role in promoting relaxation and focus by increasing brain alpha-wave activity, supporting calm mood states. Dr. Hidese of Osaka University found that this mechanism can help promote relaxation without drowsiness.
