The Role of Postbiotics and Metabolomics in Modulating the Gut-Brain Axis
Year: 2025
Type: article
Abstract: The intricate relationship between the gut and the brain, mediated by the gut microbiota, has emerged as a fundamental research field for understanding human health. Traditionally, the focus of dietary and supplementary interventions has been on probiotics and prebiotics; however, a new frontier is established with the in-depth study of postbiotics, which are inactivated microbial metabolites and components, and metabolomics, the systematic analysis of these products. This article explores the definition, mechanisms of action, and therapeutic potential of postbiotics in modulating the gut-brain axis, addressing their influence on inflammation, intestinal barrier integrity, and neurotransmitter synthesis. Furthermore, it discusses how metabolomics, through advanced techniques, allows for mapping the biochemical interactions between host and microbiota, identifying biomarkers and elucidating molecular pathways, and the intersection with nanotechnology is highlighted as a crucial advance for optimizing postbiotic delivery. Finally, future perspectives for precision nutrition and the development of personalized interventions are presented, aiming to enhance neurocognitive health and mental well-being.
