Hydrolyzed formulas are designed to help infants with specific dietary needs. One of the primary reasons for their use is to reduce the risk of cow's milk protein allergy (CMPA). Infants with CMPA may experience symptoms such as vomiting, diarrhea, or eczema when exposed to regular cow's milk formula. By using hydrolyzed formulas, these symptoms can often be prevented or minimized. Additionally, these formulas are sometimes recommended for infants with gastroesophageal reflux disease (GERD), colic, or other digestive issues.
