FDA Proposes First Infant Formula Nutrient Overhaul in 30 Years

Key points

• The FDA announced a proposed rule to update nutrient requirements for infant formula, the first major change in nearly 30 years.
• The first phase adjusts minimum and maximum levels for iodine, manganese, vitamin A, and vitamin D, while reaffirming standards for chloride, potassium, selenium, and sodium.
• Iodine requirements are tripled to 15 micrograms per 100 calories, while vitamin D minimums are doubled to 2 micrograms per 100 calories.
• The FDA is seeking public comment on making non-mandatory nutrients like DHA, ARA, and L-carnitine required, citing evidence for their role in neurodevelopment.
• The review is part of the Trump administration's Operation Stork Speed initiative, with subsequent phases covering the remaining 22 required nutrients and carbohydrate sources.
• Manufacturers would have three years from the final rule's effective date to reformulate products, meaning changes will not appear on shelves for several years.

Background

The FDA is required by law to review infant formula nutrient standards every four years, but the last comprehensive review was in 1998. In 2025, the agency launched Operation Stork Speed to accelerate this process. Previous discussions involved potential removal of seed oils, though current experts dispute the pro-inflammatory claims. The 2026 proposal follows a 2025 Request for Information and aims to align US standards with current scientific understanding of human milk composition.

How outlets are covering it

CNN and ABC News highlight the long delay since the last update and the phased nature of the review, noting that experts like Dr. Steven Abrams call the first phase 'well done' but warn that changes will not reach shelves for years. The FDA and HHS emphasize the proactive, science-driven nature of the update and the reassurance provided by new contaminant testing data. ABC News notes that previous FDA officials suggested removing seed oils, a move contested by medical experts who argue seed oils are not pro-inflammatory. All sources agree on the specific nutrient adjustments but differ in emphasis: government sources focus on safety and modernization, while media outlets highlight the timeline and expert skepticism regarding the pace of implementation.

Why it matters

Infant formula is a critical food source for millions of US babies, and outdated nutrient standards could impact health outcomes. Updating these requirements ensures that formula better mimics human milk and reflects current scientific knowledge. The potential addition of nutrients like DHA and ARA could have significant implications for infant brain development. Furthermore, the review addresses public concerns about chemical contaminants, aiming to restore confidence in the safety of infant formula. The long timeline for implementation means that current formulas remain safe, but future generations of infants will benefit from more precise nutritional standards.

What to watch

The FDA will accept public comments until February 26, 2027. Subsequent phases of the review will assess the remaining 22 required nutrients, potential new nutrient requirements, and carbohydrate sources. The agency intends to consolidate all changes into a single comprehensive final rule. Manufacturers will have three years from the final rule's effective date to reformulate and relabel their products. The FDA will continue monitoring chemical contaminants and may establish action levels for certain substances.
