During the first months of life, baby’s digestive system needs to adapt to the new environment. This is a natural process that may lead to baby’s discomfort such as colic, excess crying, and constipation. Nestlé LACTOGEN 1 is a spray dried infant formula with Probiotic (L.reuteri) for infants from birth when they are not breastfed or (exclusively top fed).
