What are DHA & ARA? What do they do?
DHA is short for docosahexaenoic acid, and ARA stands for arachidonic acid. These are fatty acids that help build your baby's brain and eyes.
Why do babies need iron?
Iron serves many biological functions, including helping in the proper formation and growth of healthy blood cells and the transportation of oxygen throughout the body. Iron deficiency can cause irreversible impairments to cognition.
What is an intact protein?
Intact proteins are proteins that aren't broken down yet; they need to be fully broken down by your digestive system when eaten. Breast milk has intact whey and casein proteins, as do most formulas. The American Academy of Pediatrics recommends starting with a routine milk-based formula, if you are formula feeding. If your baby has tolerance issues with a routine formula, consult with your health care professional to see if they recommend trying a formula with partially broken down or extensively broken down proteins, or possibly reduced lactose.
What is MFGM?
Milk Fat Globule Membrane (MFGM) is a naturally occuring component in whey protein concentrate or whey protein hydrolysate. MFGM can play an important role in brain structure and function, which supports your baby's cognitive development.
What is Palm Olein Oil?
Palm olein oil is a refined version of palm oil; the liquid component of palm oil that has undergone “fractionation” or a process that filters out crystals in the crude oil. This helps make the oil more temperature-stable, shelf-stable, and nutritious!


What are human milk oligosaccharides?
Human milk oligosaccharides, or HMOs, are immune supporting prebiotics commonly found in breast milk. They are one of the most abundant elements of human breast milk, and over 100 different HMOs have been identified. HMOs aid growth of beneficial bacteria in baby's digestive tract, and may help support immunity.
Are the HMOs derived from breast milk?
No, the HMOs in infant formula are not from human milk. They are manufactured to be structurally identical to the HMOs found in breast milk.
What are the roles for HMOs in digestive health?
HMOs aid growth of beneficial bacteria in baby's digestive tract for immune support and digestive health.
Which HMOs are in Store Brand Formulas?
Store Brand Infant Premium™ and Gentle Premium™ both contain 2'-FL (2’-fucosyllactose) HMO. Store Brand Advantage Premium™ and Sensitivity Premium™ contain both 2'-FL and LNnT (Lacto-N-neotetraose). These are two common HMOs found in breast milk and both can provide benefits to the immune system and digestion.
What is 2'-FL HMO? What are the benefits?
2'-FL (2’-fucosyllactose) is the most abundant human milk oligosaccharide found in breast milk. HMOs are immune supporting prebiotics commonly found in breast milk. They help grow beneficial bacteria in the digestive tract and may help support immunity.

Can families switch between formulas if their WIC allotment runs out?
Definitely. WIC is a supplemental nutrition program and is not intended to last the full month. When families finish their WIC formula, they can look for the store brand option that matches the nutrition of the advertised brand. All infant formula in the United States is required to meet the same strict nutrition and safety standards set by the FDA. For each formulation, we try to make it easy for families to find their store brand option by stating the comparable national brand on the package. We also use similar colors and packaging, and offer a comparison chart to the national brand on each product.
Who makes Store Brand Infant Formulas?
Perrigo is the largest supplier of store-brand infant formulas which can be found in retail locations throughout the United States, including major retailers such as Walmart, Sam's Club, Target, Kroger, CVS and Walgreens. Perrigo is a leading global self-care company. We produce store brand and national brand self-care products including over the counter medicines, oral care and nutritional products. Our mission is to make lives better by bringing quality, affordable self-care products that consumers trust everywhere they are sold. In addition to infant formulas, Perrigo's Nutrition division also distributes store brand oral electrolyte solutions and powders.
Why should consumers feel confident buying a store brand formula?
All infant formula brands provide complete nutrition for growing babies and meet FDA regulations for safety, nutrition and quality. Store brand formulas are easy to digest and contain key ingredients found in mother's milk to support a healthy baby's growth and development. Store brand formulas also meet the nutritional levels recommended by the U.S. National Academy of Science-National Research Council and the American Academy of Pediatrics, the largest organization of pediatricians dedicated to the health and well-being of infants and children. In addition, all infant formula made in the U.S. undergoes testing required by the FDA to ensure the product is safe. Store brand formula manufacturers follow this required testing protocol.
What are the differences in store brand formula from a name brand formula?
All formulas must meet the same nutritional and quality regulations from the FDA. Perrigo Nutritionals makes formulas that meet the same regulatory requirements as the leading brands. For a helpful side-by-side comparison of specific store brand formulas and national brands, visit our product pages. One major difference between store brand formulas and national brand formulas is the cost for parents. Store brand formulas contain the latest ingredients at comparable levels to the name brands without the significant marketing spending, to provide an affordable infant formula option for families.
Where are store brand formulas produced?
We produce store brand infant formulas in FDA-inspected facilities in Vermont, Ohio and Wisconsin, U.S.A. Our dairy ingredients are sourced from leading dairy markets, including the United States, Canada, and New Zealand. We do NOT produce infant formula overseas. While Perrigo sources raw materials globally, all raw materials, regardless of their country of origin, are required to meet the same stringent quality standards as their counterparts in the United States. All Perrigo infant formula products undergo testing required by the FDA to ensure the product is safe for use. Perrigo complies with the Safe Quality Food (SQF) Code, which certifies that a supplier’s food safety and quality management system comply with this international and domestic food safety standard. We also conduct a finished product surveillance testing program to further enhance product compliance, safety, and quality.

Is it safe to switch baby formula?

Clinical evidence has demonstrated that store brand formulas are well-tolerated by babies. One clinical study by University of Virginia researchers found that switching from a national brand formula to a store brand is safe and well tolerated by infants1. When you choose a store brand formula, you're choosing to feed your baby a formula that is backed by nutrition science and clinical research. We meet the same FDA standards as the big brands, and have strict safety and quality protocols. You can be confident in choosing Store Brand formulas for your baby.

What temperature water should I use to prepare infant formula?
Powdered formula will not mix well with cold or hot water. The water should be warm, at approximately 100F (40C), which is close to body temperature. This will allow the formula to mix best, and will keep baby safe from burns due to higher temperatures. Always test the temperature before feeding your baby by putting a few drops of formula on your wrist so you do not burn your baby’s mouth.
Can you prepare formula in advance?
Yes - once prepared, the formula should be refrigerated and used within 24 hours.
How should infant formula be warmed?
To warm a bottle of already prepared formula, place the bottle under running warm water, taking care to keep the water from getting into the bottle or on the nipple. Always test the temperature before feeding your baby by putting a few drops of formula on your wrist so you do not burn your baby’s mouth. Never microwave. Microwaving may cause “hot spots” where some parts of the formula will heat faster than other parts and can therefore cause serious burns to your baby. When overheated, heat sensitive and important ingredients may break down and other nutrients are destroyed due to the high temperatures.
Is it ok to re-warm prepared formula?
You can warm a prepared bottle once, and then it will need to be used within 2 hours. Once a baby has nursed from a bottle, bacteria from the child's mouth are introduced into the bottle. If any unused portion of baby formula is refrigerated and reheated, the bacteria will have the opportunity to multiply. Refrigeration will not prevent the growth of the bacteria. Therefore, you should fill each bottle with only the amount of formula needed for one feeding. After feeding, you should discard any unused formula.
How long can prepared formula be unrefrigerated?
Formula that is removed from refrigeration should be used within two hours or discarded. Because of possible bacterial contamination, formula remaining in a bottle one hour after the start of feeding should also be discarded
How long do I have to use the powdered formula once it's opened? Why?
Once opened, powdered formula should be used within 30 days, unless otherwise stated on the label. The formula may have sensory issues after 30 days of opening due to oxidation.

What is cow's milk allergy?

Cow's Milk Allergy (CMA) is one of the most common food allergies during infancy.1 It is the the body creating a negative response to the protein in cow's milk. This allergy can affect up to 3% of babies during the first year of life.1

Cows' milk allergy can cause a wide range of symptoms, including:

  • skin reactions-  such as an itchy rash or swelling of the lips, face and around the eyes
  • digestive problems – such as stomach ache, vomiting, colic, diarrhea or constipation
  • hay fever-like symptoms – such as a runny or blocked nose
  • eczema that does not improve with treatment.

If you think your baby may have an allergy, meet with your healthcare professional for more information and recommendations.

Can a premature baby consume Store Brand formula and if not, why?
Powdered formulas are not sterile, and should not be used by premature infants, or infants who may have immune problems unless directed by the baby's doctor. Premature infants often require different nutrients than a healthy full-term infant.
