What should I know about formula?

Breast milk is the optimal source of nutrition for infants. The American Academy of Pediatrics (AAP) recommends iron-fortified infant formula as an appropriate alternative during the first year of life, when breast milk is not available.

A variety of formulas are sold for infants who are not breastfed or who are partially breastfed.

Formulas include:

  • Cow's milk–based formulas and soy-based formulas, which are fortified with iron
  • Hypoallergenic formulas for those with or at risk for allergic conditions
  • Other formulas designed to meet certain dietary needs, such as galactose-free formulas1

Infants who drink enough formula and are gaining weight appropriately usually do not need extra vitamins or minerals, as long as the formula is fortified with vitamin D and iron. Your health care provider may prescribe extra fluoride if the infant formula is mixed with non-fluoridated water.2

Infant formulas can be purchased in the following forms:1

  • Ready to use: Do not need to be mixed with water
  • Powdered: Must be mixed with water
  • Concentrated liquid: Must be mixed with water

The U.S. Food and Drug Administration (FDA) closely monitors infant formulas to make sure they meet certain standards of nutrition for infants.1
