All About Nutramigen Infant Formula

Nutramigen is an infant formula developed to fulfill the nutritional needs of healthy babies. It offers a variety of products for newborns through 12 months, supporting optimal growth and development. This formula provides DHA and ARA for brain and eye health, and includes prebiotics and probiotics for digestive health. All this has led parents and pediatricians to trust Nutramigen for decades.

Overview of Nutramigen

Mead Johnson Nutrition makes Nutramigen and is available worldwide. It comes in different forms, flavors, and concentrations to fit each stage of a child’s life. All products meet or exceed US infant formula standards. Nutramigen is a nutrient-rich formula for infants with food allergies or digestive issues who cannot tolerate cow’s milk proteins, such as whey and casein. All Nutramigen formulas are gluten-free and gentle on babies’ digestive systems. Nutramigen provides all the essential vitamins and minerals babies need while being gentle on digestion.

Benefits of Nutramigen

Nutramigen is a complete formula that provides omega-3 fatty acids, vitamins, and prebiotics for healthy growth and digestion. This hypoallergenic formula supports growth and reduces allergy risks by breaking down proteins for easy digestion. The two prebiotics, oligosaccharides and GOS, support gut health and immunity.

Types of Nutramigen

Nutramigen comes in three types: LGG (with added probiotics), AA (for severe milk protein allergies), and PurAmino (for the most sensitive babies). Each provides tailored allergy and nutritional support. Here is a closer look at each type.

Nutramigen with Enflora LGG

Nutramigen with Enflora LGG is a powdered formula containing hydrolyzed protein and added probiotics (Lactobacillus rhamnosus GG). This hypoallergenic formula alleviates colic related to cow’s milk allergy. It is recommended for babies with moderate cow’s milk protein allergy needing probiotic support. Nutramigen with Enflora LGG is for babies who need a formula free of common allergens. It supports growth and is suitable for those who can’t use standard formula or rely solely on breast milk. The ingredients of Nutramigen with Enflora LGG typically include:

• Hydrolyzed protein (from cow’s milk): The protein has been broken down into smaller pieces for easier digestion.
• Corn syrup solids: A source of carbohydrates for energy.
• Vegetable oil: A source of fat for growth and development.
• Enflora LGG: A probiotic strain that supports gut health.
• Vitamin and mineral mix: Includes calcium, phosphorus, and iron for growth and development.
• Taurine, L-carnitine, nucleotides: Support brain and eye development.

Nutramigen Hypoallergenic Formula

Nutramigen Hypoallergenic Formula is formulated for infants and toddlers with cow’s milk allergy or intolerance. It uses specialized proteins to reduce the severity of allergic reactions. This version is for babies with confirmed milk allergy who do not need an amino acid-based formula. Nutramigen provides complete nutrition and is free from lactose, gluten, and soy, with only small amounts of milk proteins, to help babies with allergies grow well. The ingredients in Nutramigen Hypoallergenic Formula are:

• Water
• Lactose-free milk protein isolate (made from casein and whey)
• Vegetable oils (soy, coconut, sunflower, safflower)
• Corn syrup solids
• Medium-chain triglycerides (MCT) oil
• Trace ingredients: calcium phosphate, magnesium chloride, zinc sulfate, iron, and other minerals.

Some versions add prebiotics and probiotics to support gut health.

Nutramigen Lipil with Enflora LGG

Nutramigen Lipil with Enflora LGG is for babies sensitive to cow’s milk proteins, offering broken-down protein and probiotic support. This formula should only be used under medical supervision, as recommended for infants with specific sensitivities. Main ingredients include modified corn starch, vegetable oils, hydrolyzed casein, amino acids, and Enflora LGG probiotics.
