Probiotic drops aim to boost gut health in C-Section infants
NCT ID NCT07608341
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether daily probiotic drops plus vitamin D3 can improve early gut bacteria in healthy babies born by C-section. 150 infants will receive either probiotic or placebo drops for 8 weeks, with stool samples and questionnaires. Results will be compared to vaginally born babies. The goal is to see if probiotics can help C-section infants develop a healthier gut microbiome.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Probiotic drops with vitamin D3
- What this could lead to
- If it works, this could help C-section babies develop a healthier gut microbiome, potentially reducing future health risks.
- What could go wrong
- This is an early-stage trial with no phase, so results are uncertain. The study is small (150 infants) and may not apply to all C-section babies.
