What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Green tea leaf extract contains L-theanine, which is supported by moderate evidence for promoting relaxation and cognitive focus. Stevia leaf extract serves as a non-nutritive sweetener with a well-documented safety profile. The overall evidence for these ingredients in a liposomal delivery format remains limited.
