The Active Ingredient Is: L-Theanine

L-Theanine is basically a non-protein amino acid mostly found in green tea, recognised for helping create a calm, balanced mindset without making you sleepy.

This variant is usually sold as a pure amino acid, with source notes pointing to extraction from Camellia sinensis greens and its stability in vegan-friendly capsules.

What Does L-Theanine Do?

L-Theanine helps with normal cognitive and mood regulation by promoting a calm mind and aiding in stress response, which lines up with EFSA-backed ideas of relaxation and focus through natural amino acid activity.

Research from Dr. Hidese at Osaka University and colleagues found that L-Theanine links to reduced stress and anxiety in people under pressure, supporting its role in keeping a calm yet alert state.
