Research Highlights Potential of Psychobiotics for Psychiatric and Cognitive Disorders, Especially Depression
A 2024 systematic review of 51 randomized controlled trials indicates promising evidence for psychobiotics in treating psychiatric and cognitive disorders, particularly depression. The research, published in Nutrients, involved 3,353 participants and explored the gut-brain axis, an area of active scientific investigation. While the findings suggest therapeutic potential, the review also emphasizes that results varied across different conditions and interventions, highlighting the need for further high-quality research. The gut-brain axis describes the complex communication network between the gut microbiome and the central nervous system, where gut bacteria produce neurotransmitters that can influence mood and cognitive functions. The study underscores that understanding the science, evaluating the evidence, and substantiating claims are crucial for translating this research into effective nutritional strategies. Postbiotics, which are inanimate microorganisms or their metabolic by-products, are also being...
