Probably not a fit

Infants who were born prematurely may not benefit from this study due to their unique health considerations.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates how a mixture of human milk oligosaccharides (HMOs) influences the gut microbiota and immune system development in healthy infants. Participants will consume either the investigational product or a placebo for six months, while their parents will collect stool samples and report any gastrointestinal symptoms through an electronic questionnaire. The study will also include a reference group of breastfed infants undergoing similar monitoring without the investigational product. A total of 230 infants will be randomized into the intervention arms, with an additional 104 infants in the reference group.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of how HMOs contribute to infant gut health and immune system maturation, potentially leading to improved health outcomes.

How similar studies have gone: Other studies have shown promising results regarding the impact of HMOs on infant health, suggesting this approach has potential.
