Second Generation Human Milk Oligosaccharides Blend Study

Updated on 24 January 2021


The aim of this trial is to show that infants fed these new formulas, containing a blend of 5 Human Milk Oligosaccharides (HMOs), allow for growth in line with infants fed formulas without HMOs.

There will be different groups in the trial: three formula-fed groups and a breastfed group.


These 5 HMOs are identical to the ones found naturally in human milk. They are natural prebiotics (or complex sugars) with potential health benefits. Prebiotics are natural compounds that help the establishment of beneficial gut bacteria (such as bifidobacteria), while preventing bad bacteria from doing harm. Supplementing diets with certain prebiotics has been shown to be well tolerated in adults and infants and to provide potential benefits.Therefore, the trial also aims to understand if consuming HMOs supplemented formulas could strengthen immunity and prevent common illnesses (for example, respiratory illnesses) in infants and toddlers. Furthermore, stool frequency and consistency will be monitored, so as to evaluate digestive tolerance to the formula.
