Introducing Enfamil Infant Dual Probiotics. Probiotics are often called 'beneficial' bacteria because they’re the good guys in the gut working hard to help keep it healthy. But it’s easy for an infant’s system to get out of balance, and for the “bad” bacteria in the gut to start causing problems because their digestive systems are still developing. Using Enfamil Dual Probiotics as part of your baby’s routine can help add beneficial bacteria in their gut and help support healthy development. Infant Probiotic with Vitamin D complements breast milk and formula for optimal nutrition to help babies build strong bones.* Prebiotic/ProbioticA product that carries an unqualified on-pack statement about the product containing prebiotic or probiotic ingredients.
