FDA proposes first-phase update to U.S. infant formula nutrient rules
The FDA on Thursday proposed changing iodine, vitamin A, vitamin D and manganese limits in infant formula and keeping chloride, selenium, potassium and sodium ranges, Reuters reported, matching an FDA notice.
The U.S. Food and Drug Administration on Thursday proposed changing nutrient limits and labeling rules for infant formula sold in the United States, the first of three planned phases in a broader review2,3.
The proposal, if finalized, would update or reaffirm specifications for eight of the 30 nutrients FDA requires in infant formula2. FDA described the work as a priority under Operation Stork Speed2. Reuters reported the review also increased testing for heavy metals and other contaminants1.
The unpublished proposed rule would raise the iodine minimum from 5 to 15 micrograms per 100 kilocalories and lower the iodine maximum from 75 to 50 micrograms per 100 kcal3. For manganese, it would lower the minimum from 5 to 1 microgram per 100 kcal and set a maximum of 50 micrograms per 100 kcal3.
Vitamin A would be measured in microgram retinol activity equivalents instead of International Units, with a lower minimum of 70 micrograms RAE and a lower maximum of 120 micrograms RAE per 100 kcal, and only preformed vitamin A would count toward those limits2,3. Vitamin D would be measured in micrograms, with a higher minimum of 2 micrograms and a higher maximum of 3 micrograms per 100 kcal3.
FDA said current minimums and maximums for chloride, selenium, potassium and sodium remain appropriate2,3. It is asking for comments on possible future requirements for nutrients not now required, including DHA, ARA and L-carnitine2.
The proposed rule estimated annualized manufacturer costs of $8.4 million to $31.7 million, with a primary estimate of $17.6 million at a 7 percent discount rate3. Reuters reported the same cost range1. FDA said it would later propose rules on remaining nutrients and issue one comprehensive final rule, with independent peer review of the science used2,3.
A Federal Register public-inspection posting listed the unpublished proposed rule as document 2026-22273, docket FDA-2026-N-10832, filed Oct. 29, 2026, and scheduled for publication Nov. 2, 20263. Comments would be due 120 days after Federal Register publication2,3.
FDA said infant formulas now on the U.S. market remain safe for babies2. Reuters noted the agency has also urged tighter supplier oversight after recalls and recent infant botulism cases1. Not medical advice.
