The Food and Drug Administration (FDA) announced on Thursday it is proposing a new rule that will update the nutrient requirements for infant formula.

The Department of Health and Human Services (HHS), which oversees the FDA, said in a press release that it would be the first major update to infant formula standards in nearly 30 years.

The proposed rule would update requirements for vitamin A, vitamin D, iodine and manganese as well as reaffirm existing requirements for chloride, potassium, selenium and sodium, the agencies said.

It would also change the units of measure for two nutrients and request public input on possible requirements for ingredients not currently required in infant formula but sometimes added by manufacturers, they noted.

The ingredients not currently required include arachidonic acid (ARA), docosahexaenoic acid (DHA), and L-carnitine. Some studies have suggested they contribute greatly to infant growth, brain development and health.
