scFOS supplemented follow-on formula in healthy infants: Impact on vaccine specific faecal secretory IGA response, faecal bifidobacteria, growth and digestive tolerance

A follow-on milk formula supplemented with scFOS modulates intestinal microbiota via an increase of faecal bifidobacteria concentration, while no effect on sIgA concentrations could be demonstrated. scFOS addition elicited normal digestive tolerance and normal growth suggesting it can be used safely at 5 g/L in infants after 4 months of age.
