FDA Proposes New Iodine and Vitamin D Levels for Infant Formula

The Food and Drug Administration is proposing updates to the nutrient requirements for infant formula, marking the first comprehensive review of the standards in nearly 30 years. The Department of Health and Human Services announced the initial phase of a three-part proposal on Thursday. This first rule specifically targets the required levels of iodine, manganese, vitamin A, and vitamin D. It also reaffirms existing thresholds for chloride, potassium, selenium, and sodium.

The proposal includes a change to the units of measure for two specific nutrients. It further seeks public feedback on whether to mandate ingredients that manufacturers sometimes include voluntarily. These optional components include arachidonic acid, docosahexaenoic acid, and L-carnitine. The agency cited evidence suggesting these ingredients support neurodevelopmental health in infants. Future phases of the review will address other required nutrients, potential new mandates, and carbohydrate sources.

The FDA intends to consolidate all proposed changes into a single final rule. The agency has opened a window for public comment, inviting input from parents, healthcare professionals, and researchers. Submissions are due by Feb. 26. This process allows stakeholders to review the technical details before the final standards are set.

Alongside the nutrient proposal, the FDA released new data on chemical contaminants in infant formula products sold in the U.S. The agency tests samples for pesticides, PFAS, phthalates, and heavy metals including arsenic, cadmium, lead, and mercury. The results indicated that most samples contained low or non-detectable levels of these contaminants. The agency characterized the findings as reassuring.

To improve transparency, the FDA launched a new public dashboard where consumers can view the contaminant testing results. The agency stated it will continue to monitor and test formula for contaminants. It said it will take action when appropriate based on future testing data. The new digital tool makes the specific test results for various brands accessible to the public.

HHS Secretary Robert F. Kennedy, Jr. commented on the release in a news statement. He stated, "Parents deserve confidence in every bottle they feed their baby." The Secretary linked the initiative to the Operation Stork Speed and Make America Healthy Again agenda. He added that the administration is proposing stronger nutrient requirements and placing test results directly in parents' hands. He said the agency will hold manufacturers to rigorous scientific standards.

The proposal represents a shift in how the agency manages the infant formula market. By updating the nutrient standards and publishing contaminant data, the FDA aims to align regulatory requirements with current scientific evidence. The final rule will establish the binding standards for manufacturers across the U.S. market.
