Do infants fed infant formulas need to take additional vitamins and minerals?
Infants fed infant formulas do not need additional nutrients unless a low-iron formula is fed. If infants are fed a low-iron formula, a health care professional may recommend a supplemental source of iron, particularly after 4 months of age.
FDA's nutrient specifications for infant formulas are set at levels to meet the nutritional needs of infants. In addition, manufacturers set nutrient levels for their label claims that are generally above the FDA minimum specifications and they add nutrients at levels that will ensure that their formulas meet their label claims over the entire shelf-life of the product.
