The aim of this study is to demonstrate that a dietary supplementation with a novel prebiotic combination is safe, well tolerated and able to improve overall health of toddlers.

The fermentation of a novel prebiotic combination leads to a modulation of the gut microbiota composition, in particular to a growth stimulation of bifidobacteria, and the production of organic acids like lactate and short-chain fatty acids (SCFA).The efficacy of the prebiotic combination to improve toddler's digestive function will be addressed. The overall health will be assessed as a measure of reduced number of febrile days resulting in less days of absenteeism from daycare centers.
