What’s in Similac® Formula? Baby Formula Ingredients & Nutrition
Similac products give babies a strong start with important baby formula ingredients.
Whether you’re formula feeding or looking for an option for supplementing, supporting your baby’s growth and development means nourishing him with the right nutrition. That’s why Similac formulas have important vitamins, minerals, and nutrients to help give your little one a strong start.
What’s in Similac Baby Formula?
Protein to Power Growth
Protein helps to build, maintain, and repair tissues in the body. It also helps to produce enzymes, hormones, and antibodies. The protein ingredients most often found in Similac milk-based formulas are nonfat milk and whey protein concentrate from cow’s milk.
Fat & Fatty Acids: DHA for the Developing Brain
About 50% of the calories in breast milk and infant formulas come from fat. All baby formulas contain a blend of different fats and oils that provide important fatty acids (like DHA) for normal brain and eye development.
Similac formulas have no palm olein oil, which means excellent calcium absorption for strong bones.
Carbs for Energy and to Fuel Growth
Carbohydrates are an important energy source that fuels the body’s normal day-to-day activities. Babies, especially, need carbohydrates to help them grow and gain weight.
Lactose is the carbohydrate found in breast milk and in many cow’s milk-based infant formulas. Formulas for sensitive babies often use a different carbohydrate, like corn maltodextrin or corn syrup for babies with lactose sensitivity.
HMO*Prebiotics for Immune Support and More
A large part of our immune system is in our gut. That's why it's important to pay attention to it. Good gut health relies on nurturing the good bacteria found there. Prebiotics do that by feeding the good gut bacteria and helping them to multiply.
Select Similac formulas include the prebiotic 2’-FL HMO.* This prebiotic is structurally identical to the 2’-FL HMO found in breast milk. Similac formulas may also contain the prebiotics fructooligosaccharides (FOS) or galactooligosaccharides (GOS).
Our Similac® 360 Total Care® formulas have an exclusive blend of 5 of the most abundant HMO prebiotics found in breast milk: 2’-FL, 3-FL, LNT, 3’-SL, and 6’-SL. These formulas support baby’s whole-body growth and development, and have the closest prebiotic blend to that in breast milk.
*Human milk oligosaccharide; not from human milk.
Lutein for Eye Development
Lutein and beta carotene are carotenoids that are naturally found in breast milk that are also added to many Similac formulas. These pigments are important for your little one’s eye development.
Key Vitamins for Babies
Baby formulas have vitamins babies need to regulate the processes in their bodies. Here are some key vitamins listed below and how they support your baby’s growth:
Vitamin E – Supports developing cells
Vitamin D – Essential for maintaining strong bones and healthy muscle
Vitamin A – Supports vision, growth, cell division, and the immune system
Common Minerals in Baby Formula
Healthy bones, teeth, and nails are built with the help of minerals. Baby formula has a long list of minerals, but these are some of the common minerals you hear about and how they support the growth of your little one:
Iron – Essential for healthy blood and carrying oxygen throughout the body
Calcium – Important for bone development and circulation
Phosphorus – Supports development of the skeleton
Zinc – Supports tissue growth and repair, wound healing, and a healthy immune system
