Why WIC Families Have Fewer Formula Choices Than Other Parents,And What It Means for Baby Safety

Families relying on the WIC program (Special Supplemental Nutrition Program for Women, Infants, and Children) have significantly fewer infant formula options than parents who can buy any brand off the shelf. While WIC serves an estimated 56 percent of all infants consuming formula in the United States, the program's state-by-state contracting system means eligible families are often limited to just one primary brand, even though independent testing has identified safer, lower-contaminant options available on the open market.

The issue isn't about safety standards. All infant formulas sold in the U.S. must meet federal nutritional requirements, including providing at least 10 milligrams of iron per liter and at least 67 kilocalories per 100 milliliters at standard dilution. However, recent independent testing by Consumer Reports has revealed significant differences in contaminant levels between brands, raising questions about whether the current WIC system is truly serving vulnerable infants equitably.

How Does WIC Decide Which Formula Brands Families Can Buy?

Most states use a competitive bidding process to select which infant formula brand will be covered by WIC. Formula manufacturers submit rebate bids offering discounts for each can purchased through the program. The state then awards a contract to the company offering the highest discount on the wholesale price. This system allows WIC to stretch its limited funding and serve more families, but it comes at a cost to consumer choice.

In practice, this means almost all infant formula provided by WIC comes from just two companies: Abbott, which makes Similac formulas, and Mead Johnson, which makes Enfamil formulas. When states do offer formulas from other manufacturers, they are typically specialized formulas for specific dietary needs and usually require a prescription. For example, as of May 1, 2026, all WIC families in Illinois will choose from Similac formula products only. California, which operates the largest WIC program in the country, offers families access to Enfamil milk-based formula and Similac soy-based formulas. Texas families have access primarily to Enfamil formulas, with one Similac soy-based option.

What Did Independent Testing Reveal About Formula Safety and Contaminants?

Since 2025, Consumer Reports has tested 90 infant formulas for heavy metals, including lead and arsenic, as well as process contaminants. The results were concerning. Many soy, plant-based, and hypoallergenic brands included in the testing had inorganic arsenic levels above experts' levels of concern. The testing also found that many formulas included per- and polyfluoroalkyl substances (PFAS), which are synthetic chemicals linked to negative health outcomes.

However, the testing also identified some formulas with lower contaminant profiles. Organic formulas tested lower for heavy metals and other contaminants on average than non-organic formulas. Additionally, contaminant levels varied between different products under the same brand, suggesting that some manufacturers maintain stricter quality controls than others. The two formulas covered by WIC that rated among Consumer Reports' Top Choices for having low to non-detectable contaminants in independent tests were Similac Advance and Enfamil Infant formulas in their powdered form.

How to Navigate Formula Choices When Using WIC

• Ask Your Pediatrician About Alternatives: If your baby has feeding intolerance or a medical condition requiring a specialty formula, a pediatric provider can work with your state's WIC program to ensure your baby receives an appropriate alternative formula beyond the standard contract option.
• Understand Your State's Specific Options: Contact your state WIC agency to learn exactly which brands and formula types are covered in your area, as options vary significantly from state to state and change periodically.
• Request Lactation Support: WIC provides infant nutrition counseling and lactation support services. Speaking with a WIC lactation counselor can help you explore all feeding options available to your family.
• Know the Difference Between Brands: While all WIC-covered formulas meet federal safety standards, differences exist in ingredient sourcing, manufacturing transparency, and third-party testing practices between manufacturers.

The real challenge for WIC families is financial. If a parent wants an organic formula, a non-contract brand, or a formula with lower contaminant levels identified in independent testing, they typically have to pay out of pocket. For many low-income families, that makes choosing a specific brand a significant financial burden.

"For many families, that makes choosing a specific brand a significant financial burden," explained Dr. Caitlin Goodwin, a certified nurse midwife. "Parents can trust that these products provide the essential calories and nutrients babies need to grow. The real differences between brands usually come down to ingredient sourcing, manufacturing transparency, and whether the company does extra third-party testing."

Why Does This Matter for Babies' Health?

Infants are uniquely vulnerable to toxins like heavy metals because their kidneys and liver functions are still developing. Babies from low-income families, who are more likely to rely on WIC, face a particular equity concern. They have the same exposure risk to contaminants as any other infant, yet they have fewer options to access formulas with lower contaminant profiles.

The difference in regulations between the United States and the European Union also highlights a gap in protection. The FDA's "Closer to Zero" action plan aims to reduce heavy metals in baby foods, but it does not apply to baby formula. The European Union often maintains even stricter limits on contaminants in infant formula than the U.S. does. From a clinical standpoint, experts argue the goal should be to move toward more proactive, public testing to better protect infant health and give all parents, regardless of income, peace of mind.

WIC plays a critical role in supporting infant nutrition across the country. However, the current state contracting system raises important questions about equity and access to the safest available options. As independent testing continues to identify differences in formula quality and contaminant levels, the conversation about whether WIC's system should evolve to allow for more consumer choice is becoming increasingly urgent for families and health advocates alike.
