An eHF is a formula where the proteins in cow milk have been hydrolyzed. Extensively hydrolyzed proteins mean that the protein in the
formula has been broken down to only consist of very small peptides and free amino acids, which are the building blocks of protein.
The proteins are carefully produced this way so that the formula will be tolerated by infants with allergy to cow milk. In the United
States, all formulas that are labeled as being "hypoallergenic" must also demonstrate tolerability by infants with allergy to
cow's milk in a clinical study based on criteria established by the American Academy of Pediatrics (AAP). Pepticate infant formula has
been clinically demonstrated to be hypoallergenic by this standard. Extensively hydrolyzed protein-based formulas are different than
formulas described as partially hydrolyzed. The proteins in partially hydrolyzed formulas are not broken down to the extent of the
proteins in eHFs and may not be appropriate for infants with a food allergy who require a hypoallergenic
formula.
