    Published in Nutrition Reviews

    Methodology

    Umbrella review of 58 meta-analyses covering 175 randomized trials of 11 nutritional interventions in adults with IBS, with effect sizes recalculated under random-effects models and certainty graded with GRADE.

    Key Findings

    Soluble fiber, peppermint oil and aloe vera improved IBS symptoms; vitamin D3 and curcumin improved symptom severity, but overall certainty of evidence was low.

    Conclusions

    Several supplements modestly reduce IBS-related abdominal pain, but evidence certainty is generally low.

    Limitations

    Low GRADE certainty across most comparisons; heterogeneity between the pooled meta-analyses.
