ClinConnect Summary

The Probiotic in Infant Growth, Allergy and Immunity Study aims to understand how a specific probiotic (Bifidobacterium animalis subsp. lactis strain BLa80) can help healthy infants and young children grow and develop better. This study will look at how the probiotic affects their physical growth, gut health, immune system, and the likelihood of allergies. Researchers will also ensure that the probiotic is safe for infants and young children.

To take part in the study, infants must be healthy, born at full term (37 to 42 weeks of pregnancy), and weigh between 2500g and 4000g at birth. Only children without diagnosed allergies or serious health issues will be considered. Parents or caregivers will need to agree to provide stool samples during the study and refrain from giving any other probiotic products while participating. The study is not yet recruiting participants, so more information will be available soon for those interested in enrolling their healthy infants or young children.
