From DHA to prebiotics, here's the full tea on what's actually in your baby’s formula.
Last Updated On: August 27, 2026
Every scoop of baby formula delivers the essential nutrients your little one needs for growth and development. While each Enfamil product is tailored for specific feeding needs, most formulas share a foundation of key nutrients that help nourish your baby from the very first bottle.
Protein is the building block of your baby’s growth—supporting muscle development, tissue repair, and immune health. Most Enfamil formulas use a mix of whey proteins like the ones naturally found in breast milk to help support your baby’s growth.
For families who prefer plant-based options, Enfamil also offers soy protein formula that provides balanced nutrition while not using dairy ingredients. Soy comes from soybeans and is a source of plant-based protein found in many familiar foods, including tofu and meat alternatives. Soy protein is used in some plant-based baby formulas, such as Enfamil® ProSobee®, to provide a source of protein without cow’s milk.
Fats fuel brain development and energy.1 Enfamil includes important fatty acids like DHA for brain and eye support. Some formulas use palm olein oil as part of a blend of vegetable oils to help bring the fatty acid profile of formula closer to that of breast milk. Palm olein oil is rich in palmitic acid, a major fatty acid found in breast milk.
Carbohydrates provide energy. Most Enfamil formulas include lactose as the primary carbohydrate source, which is meant to mimic the content of breast milk. Most infants can digest and tolerate lactose well.1
However, some babies do have trouble digesting lactose. If your doctor recommends switching to a lactose-free formula, Enfamil also has a line of formulas that use corn syrup solids as a safe, digestible carbohydrate source that provides energy without added table sugar.
Your baby’s body needs a range of vitamins and minerals for growth and health. Enfamil formulas include vitamins and minerals to support vision, bone strength, and antioxidants as well as iron for brain development and oxygen transport.2,3
Enfamil formulas have Vitamin A to support healthy eyes and immune function.
Prebiotics and probiotics nourish your baby’s developing gut microbiome, supporting digestion and immune health. You’ll find galactooligosaccharides (GOS) and polydextrose (PDX) prebiotics in some of our formulas. Research has shown that infants who drink formula that has GOS and PDX have softer stools and a concentration of Bifidobacterium gut bacteria that’s closer to babies who drink breast milk.4 Overall, this can contribute to immune function and overall gut health.5
Lactobacillus rhamnosus GG (LGG®) is a probiotic that supports gut health and is the most studied probiotic for allergy management. This probiotic is found in Nutramigen® with Probiotic LGG®, a hypoallergenic infant formula.
MFGM (Milk Fat Globule Membrane) is a naturally occurring component that surrounds fat droplets in breast milk and contains nutrients that support brain development. Clinical studies suggest that MFGM added to formula may support cognitive development in infants, especially when paired with other key nutrients like DHA and choline. Enfamil NeuroPro® has MFGM and DHA as a brain-nourishing blend.
Baby formula also has other important nutrients that support your baby’s growth and development. Here are a few you may see on an Enfamil formula ingredient list:
We’ve used our decades of research to use ingredients in Enfamil formula that are inspired by the structure or function of those naturally found in breast milk. Proteins support strength and tissue, DHA supports brain and eye development, and prebiotics support the immune and digestive system.
Together, they help create a nutritional foundation that’s inspired by breast milk.
Parents deserve confidence in what goes into their baby’s bottle. That’s why Enfamil formulas are made using trusted ingredients and undergo extensive testing for quality, purity, and consistency.
Our blends are built on decades of research into breast milk composition and infant development. Every formula is developed by scientists and pediatric nutrition experts to ensure complete, balanced nutrition you can trust.
