Effects of an Infant Formula and follow-on Formula Containing Bio-active Ingredients on Growth, Tolerance and Infections

In this clinical trial, the growth (weight for age), product tolerance (product intake, comfort) and infection-related symptoms of healthy infants consuming an IF and FOF containing bio-active ingredients will be evaluated and compared to a group of infants consuming a standard IF and FOF, until the age of 1y. 456 healthy term infants who are exclusively formula-fed will be included <2mo of age. An exploratory follow-up assessment will be done at the age of 2 and 3 years to study sustained health effects.
