Definition of Soy milk allergy
Medically reviewed by Min Clinic Staff | Updated: January 2026
Soy milk allergy: Soy protein formulas contain no cow milk and are therefore reasonable alternatives for infants with true cow milk allergy.
However, some infants have allergy to both cow milk and soy proteins. These infants require a formula in which the cow milk protein (casein) has been "predigested" and specific amino acids added to provide a formula that can provide proper nutrition.
The decision to utilize one of these specialized formulas should be made in consultation with the infant's pediatrician.
