Introduction
A 3-year-old child with cow’s milk allergy can consume hydrolyzed formula. Children allergic to cow’s milk protein cannot drink standard infant formula; moreover, most infants with cow’s milk protein allergy are also allergic to goat’s milk formula. Only specially formulated hydrolyzed formulas—designed specifically for allergic infants—are unlikely to trigger an allergic reaction. Hydrolyzed formulas break down cow’s milk proteins into free amino acids, resulting in amino acid-based formulas that contain no intact cow’s milk protein molecules.
A 3-year-old child with cow’s milk allergy can consume hydrolyzed formula. Children allergic to cow’s milk protein cannot tolerate standard infant formula; moreover, most infants with cow’s milk protein allergy also react adversely to goat’s milk formula. Only extensively hydrolyzed or amino acid-based formulas—specifically designed for allergic infants—are generally well tolerated.
Hydrolyzed protein formulas contain proteins that have been completely broken down into individual amino acids, rendering them non-immunogenic. These formulas are primarily indicated for the management of severe cow’s milk protein allergy or for cases involving multi-system clinical manifestations. While their caloric and nutritional profiles match those of standard infant formulas, they are associated with certain limitations and side effects. A key limitation is that, because free amino acids lack immunogenicity, they cannot induce immune tolerance to cow’s milk protein in infants. Additionally, hydrolyzed formulas often have a bitter, unpleasant taste, which may lead to poor acceptance and reduced intake. Prolonged inadequate consumption may compromise normal nutrition and growth.
Hydrolyzed formulas are specifically developed for infants with cow’s milk protein allergy. In amino acid–based formulas—the most extensively hydrolyzed type—cow’s milk protein molecules are entirely replaced by free amino acids; thus, no intact cow’s milk protein remains, eliminating the trigger for allergic reactions. With consistent use over time, such formulas serve as an effective therapeutic intervention for cow’s milk protein allergy.
