NCT ID NCT07404930
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether giving a probiotic supplement (Lactobacillus reuteri) to nursing mothers could change the bacteria in their breast milk and help establish healthy gut bacteria in their newborns. 70 mothers and their babies took part. The researchers measured bacterial levels in milk and baby stool samples before and after 30 days of supplementation.
