Brief Summary

The aim of the present prospective study is to investigate whether the consumption of certain probiotic strains over a six-month winter/spring season would be able to affect the incidence and duration of upper respiratory tract infections, in otherwise healthy children as well as determining whether a combination of two strains would perform differently from a single strain version.

Outcome Measures

Primary Outcomes (1)

  • To examine if the consumption of two different probiotic strains added to milk at the point of consumption could reduce the "flu-like" symptoms and other symptoms of illness of preschool-age children in day care centers.

    Daily for six months

Secondary Outcomes (1)

  • To determine if children who consume a beverage fortified with a probiotic miss fewer days of preschool as measured by illness.
