Présentation de la L-théanine - Un acide aminé unique et puissant que l'on trouve principalement dans la centrale à thé, Camellia sinensis. Provenant des meilleures feuilles de thé vert, cet ingrédient est responsable de la saveur distincte de la boisson populaire. Mais il ne s'agit pas seulement du goût - des preuves préliminaires suggèrent que la L-théanine peut également avoir des effets bénéfiques sur les aspects psychologiques et physiques du stress quotidien, y compris l'anxiété et la tension occasionnelles. Comment ça marche? Des études humaines ont montré que la prise de la L-théanine peut avoir un impact sur la production d'ondes alpha dans le cerveau, conduisant à des sentiments de relaxation et à une concentration améliorée. Et avec la capacité de traverser la barrière du cerveau sanguin, la L-théanine peut soutenir des niveaux de neurotransmetteurs sains et même contrecarrer les effets stimulants de la caféine.

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.
