The Active Ingredient Is: L-Theanine (Suntheanine)

L-Theanine is a natural amino acid found in tea that supports relaxation and a calm mental state. This form, Suntheanine, is a patented, pure L-Theanine used in supplement form and sourced from green tea.

This ingredient contains Suntheanine as the active component, with supporting ingredients limited to the capsule materials and stabilisers as listed in product information. The aim is to provide a standardised, high‑quality source of L-Theanine for its relaxing properties.

What Does L-Theanine Do?

L-Theanine helps promote a relaxed mood and can support a calm mental state without sedation, in line with EFSA‑aligned and NHS‑recognised discussions of normal cognitive function. Dr. Hidese of Jichi Medical University found that Suntheanine supports relaxation and attention under stress.

It plays a role in normal brain function and stress processing, contributing to everyday emotional balance as part of a healthy lifestyle.
