FDA proposes updating nutrient rules for infant formula in phased review
By Life and Health Today Staff, . Life and Health Today.
The Food and Drug Administration published a proposed rule on October 29, 2026, that would revise the nutrient standards infant formula manufacturers must meet, according to the FDA's own announcement and a notice in the Federal Register.
What the proposal would change
Infant formula sold in the United States must contain specific amounts of roughly 30 nutrients, set by federal regulation. The proposed rule targets eight of those nutrients. For four of them, the FDA is proposing to change the minimum level, the maximum level, or both. For at least one nutrient, the agency is also proposing to change the unit of measurement used to express the requirement, and to change which ingredient sources manufacturers are permitted to use to meet one of the requirements. Required label content would also be updated.
For the remaining four nutrients reviewed in this round, the FDA concluded that the existing required levels are still correct and reflect, in the agency's words, "the best available scientific evidence on infant nutritional requirements and safe intake levels," according to the Federal Register notice.
How this fits into a larger review
The FDA is conducting its review of all 30 infant formula nutrients in three phases and plans to consolidate any final changes at the end of the process, according to the agency's website. This proposed rule is part of that phased approach. The agency said it intends to finalize changes across phases together, meaning the rules that actually govern manufacturing will not change until the full review is complete and a final rule is issued.
A proposed rule is not a final rule. Manufacturers, researchers, and the public can submit comments before the FDA decides whether to finalize the changes, modify them, or withdraw them.
What the full proposal contains
The FDA's published summary names the categories of change but does not specify which four nutrients would see adjusted levels, what the proposed new minimums or maximums are, which nutrient's permitted source would change, or what the labeling revisions would require. Those details are in the full proposed rule, available through the Federal Register's public docket.
Parents and caregivers should note that no manufacturing requirements change until a final rule is published. Whether to continue using a current formula is a question for a pediatrician who knows the child.
