Presentazione di L -teanina - un aminoacido unico e potente trovato principalmente nella pianta del tè, Camellia sinensis. Proveniente dalle migliori foglie di tè verde, questo ingrediente è responsabile del sapore distinto della bevanda popolare. Ma non si tratta solo di gusto: l'evidenza preliminare suggerisce che la L -teanina può anche avere effetti benefici sugli aspetti psicologici e fisici dello stress quotidiano, tra cui ansia e tensione occasionali. Come funziona? Gli studi umani hanno dimostrato che l'assunzione di L-teanina può influire sulla produzione di onde alfa nel cervello, portando a sentimenti di rilassamento e miglioramento della messa a fuoco. E con la capacità di attraversare la barriera cerebrale del sangue, L-teanina può supportare livelli di neurotrasmettitore sani e persino contrastare gli effetti stimolanti della caffeina.

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.
