What this trial studies

This study investigates the gastrointestinal microbiota in healthy newborn infants by supplementing them with a specific probiotic strain for four weeks. It is a randomized, double-blinded, placebo-controlled trial conducted at Hvidovre University Hospital. The primary goal is to assess how well the probiotic strain can establish itself in the infants' gut, measured through fecal samples analyzed with quantitative Polymerase Chain Reaction (qPCR). Following the intervention, there will be a two-week follow-up period to monitor the effects.

Who should consider this trial

Good fit: Ideal candidates include healthy pregnant individuals in their late third trimester planning to exclusively breastfeed and their full-term newborns.

Not a fit: Patients with congenital disorders or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of infant gut health and potentially improve dietary recommendations for newborns.

How similar studies have performed: Previous studies on probiotics in infants have shown promising results, indicating potential benefits in gut health, making this approach both relevant and supported by existing literature.
