Across 13 studies, 11 reported beneficial effects of Lactobacillus reuteri DSM 17938 on reducing abdominal pain, with a predominant small effect size. The most commonly studied dose was 10^8 CFU/day, and effects were typically observed over 8 weeks (median study duration 56 days). Key populations include children with functional abdominal pain disorders and infants with colic.
Caveats: Two high-quality RCTs found no significant benefit over placebo, suggesting the effect may be context-dependent. One study showed a large effect in infants using a combination with vitamin D, potentially confounding the result. Most evidence is in pediatric populations; applicability to adults is limited.
