Assessment
The study is a well-conducted review that synthesizes existing research on psychobiotics and their potential impact on mood and anxiety. While it provides a comprehensive overview, the lack of new experimental data and statistical analysis limits its contribution to the field. The study is transparent and free from conflicts of interest, but further research is necessary to validate the findings discussed.
