Overview
This study aims to assess the clinical efficacy, safety and tolerance of a new formula containing a prebiotic and a mix of probiotics in the specific population of infants suffering from functional constipation through a superiority, double-blind, randomized, placebo-controlled trial.
Description
The study comprises a selection period of 1 week where the eligibility of the infant to participate in the study will be evaluated. Once his/her participation is confirmed, the tested formula will be compared to a standard formula during a 2-month study period followed by an optional follow-up period of 2 months where only the tested formula will be used.
