  • Moderate evidence3 studies

    Across 3 studies, all reported beneficial small-sized effects of *Lactobacillus reuteri* DSM 17938 on reducing vomiting frequency in infants, with all three reaching statistical significance. The evidence is strongest in healthy and breastfed full-term infants, with one small RCT using a dose of 5 drops daily (10^8 CFU) for 4 weeks. Effect sizes were consistently small across all studies.

    Dose: 5 drops daily (10^8 colony-forming units)
