PRebiotic Intervention for Metabolic and MEntal Health (PRIME)

The purpose of the study is to determine whether a daily prebiotic fibre blend can reduce systemic inflammation, dyslipidemia, and self-report measures of mental health in individuals with metabolic syndrome. This study will help shape a larger randomised controlled study (RCT) powered to assess efficacy in a bigger cohort of patients. Primary outcome measures will explore the efficacy of a prebiotic fibre blend on systemic inflammation. Secondary and exploratory outcomes measures will explore the efficacy of the prebiotic blend on clinical biomarkers associated with cardiometabolic risk factors, microbiota features, and mental health. Using these data, we will also estimate in-year savings for the NHS in the metabolic syndrome population on a per participant basis.
