FDA plans to rework four of 30 infant formula nutrient specs

What happened?

1. FDA proposed updated nutrient requirements for infant formula, which acting director Kyle Diamantas said Thursday is the first nutrition review of formula in nearly 30 years.
2. The first phase adjusts 4 of the 30 nutrients the agency currently requires: iodine, manganese, vitamin A and vitamin D.
3. The iodine minimum would rise from 5 micrograms to 15, with a new upper limit of 50 micrograms set by the proposal.
4. The manganese minimum would fall from 5 micrograms to 1 per 100 calories, with a new 50-microgram maximum established.
5. Vitamin D's minimum would double from 1 to 2 micrograms (maximum 3), while vitamin A drops from 250 IU to 233 IU per 100 calories, with units shifting to retinol activity equivalents (RAE).
6. The review is part of Operation Stork Speed, announced in March 2025; Reuters reported the proposed rule also covers labeling rules, and the proposal reaffirms requirements for chloride, potassium, selenium and sodium.

An FDA proposed rule would change the specifications for four of the 30 nutrients required in US infant formula: iodine (5 to 15 micrograms, new 50-microgram cap), manganese (5 to 1 microgram per 100 calories, new 50-microgram cap), vitamin A (250 to 233 IU per 100 calories) and vitamin D (1 to 2 micrograms, new 3-microgram maximum). Reuters reported the proposal also includes labeling rules, and vitamin A's unit of measure would shift from international units to retinol activity equivalents.
