Effect of probiotic supplementation on the gut microbiota diversity in healthy populations: a systematic review and meta-analysis of randomised controlled trials
Our results indicate that probiotic supplementation does not produce statistically significant changes in gut microbiota diversity in healthy individuals. This study highlights the need for further research to determine whether specific probiotic strains or formulations may influence diversity in targeted subgroups or under specific conditions.
