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 essential fatty acids (like DHA) for normal brain and eye development.
Similac formula Has No Palm Olein Oil –
Palm olein oil is often the first fat listed on the ingredient labels of other leading infant formulas. Palm olein oil binds to calcium in the intestine, making it difficult for calcium to be absorbed into your baby’s body. This makes it difficult for calcium to be absorbed into your baby’s body.
Similac does not use palm olein oil, which means our formulas support 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.
Prebiotics for Digestive Health
A large part of our immune system is in our gut. That's why it's important to pay attention to digestive health. Good gut health relies on nurturing the good bacteria found there. Prebiotics do that by feeding the good gut bacteria and helping it to multiply and keep the “bad” bacteria in check.
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).
*Human milk oligosaccharide
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
Similac formulas have vitamins babies need to regulate the processes in their bodies. Here are some vitamins listed below and how they support your baby’s growth:
Vitamin E – Found in breast milk and supports developing cells
Vitamin D – Functions as a hormone and is essential for maintaining strong bones and healthy muscle
Vitamin A – Supports vision, growth, cell division, and immunity
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
