Enfamil Nutramigen Colic Baby Formula with Enflora LGG probiotics is a hypoallergenic formula proven to manage colic fast, often within 48 hours. If your baby has an allergy to the cow's milk protein in infant formula, Nutramigen contains both extensively hydrolyzed protein to provide colic relief and Enflora LGG probiotics to provide immune support to prevent allergies in the future. These two ingredients offer a more comprehensive approach working together to help babies feel better faster.
