Background and Objectives: Anxiety is the feeling of worry or nervousness that may manifest as physical, cognitive and behavioral symptoms. When these symptoms persist and affect performance, anxiety can be regarded as a disorder. Several anxiety disorders have been described, including generalized anxiety disorder (GAD) and panic disorder. Maintaining a healthy diet is critical for physical and mental well-being. Recent studies have shown that the brain can be affected by dietary components and nutrients. Probiotics have become increasingly popular as part of a healthy diet due to their potential to regulate brain health through the microbiota-gut-brain axis. This review was designed to identify effective probiotic species in decreasing anxiety.
Materials and Methods: A systematic search was carried out in Google Scholar, Science Direct, PubMed and Web of Science for studies published until January 2024. The search was carried out with terms of “probiotic supplements” AND anxiety and “probiotic supplements” AND “anxiety disorders”. First, duplicated studies were removed and 2024 studies were screened. Then, 23 studies met the selection criteria.
Results: Based on the results obtained from the 23 selected studies, 16 studies showed that supplementation with probiotics improved anxiety symptoms, although the improvement was small in cases.
Conclusions: Based on the results, probiotics are sometimes effective in decreasing anxiety and can be an adjunctive treatment in persons with psychiatric disorders (e.g. depression and GAD). However, there is a need of further clinical trials with larger sample sizes. Furthermore, Lactobacillus plantarum and Bifidobacterium longum are more effective than other probiotics in decreasing anxiety. |
