Baby formula is typically made with either a milk protein or soy protein. Milk proteins can come from a cow or goat. Some manufacturers like HIPP make formulas with hydrolyzed proteins. Hydrolyzed proteins are broken down to help make it easier for baby to digest.
Although soy protein formulas are consumed by approximately 20% percent of infants in the U.S., there is oftentimes no valid reason as to why a soy-based formula is being used. Because soy contains a high level of endocrine disruptors, we recommend only using soy-based organic formula in cases where severe allergies or health conditions exist.
