Nutritional composition comprising urea, non-digestible oligosaccharides and bifidobacteria

A nutritional composition comprising urea, non-digestible oligosaccharide, and lactic acid producing bacteria, wherein the non-digestible oligosaccharide comprises one or more human milk oligosaccharides selected from the group consisting of 2′-fucosyllacose (2′-FL), 3-fucosyllactose (3 FL), 3′-sialyllactose (3′-SL), and 6′-sialyllactose (6′-SL), and wherein the lactic acid producing bacteria comprise a strain of Bifidobacterium longum ssp infantis able to express urease, and a strain of Bifidobacterium bifidum able to express at least one extracellular enzyme selected from a fucosidase and a sialidase and not able to express a urease.
