Investigation of the Efficacy of a Probiotic Mixture in Moderate Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): A Mechanistic Trial

The goal of this clinical trial is to evaluate whether a specific probiotic mixture can improve liver health in adults with moderate metabolic dysfunction-associated steatotic liver disease (MASLD). The main questions it aims to answer are: Can the probiotics improve liver fat and stiffness as measured by non-invasive imaging (FibroScan® CAP and FAST scores)? Does the probiotic affect other health markers like cholesterol, blood sugar, inflammation, and gut bacteria? Researchers will compare people taking the probiotic to those taking a placebo (a capsule with no active ingredients) to see if the probiotic has beneficial effects. Participants will: Be randomly assigned to take either the probiotic or placebo daily for 6 months. Attend 3 study visits (at the start, 3 months, and 6 months). Provide blood and stool samples. Undergo liver scans (FibroScan®). Complete a health and nutrition questionnaire. This study includes adults aged 18-65 with moderate MASLD and certain metabolic health conditions. Participants must not be pregnant, breastfeeding, or taking certain medications or supplements that could interfere with the study.
