This is a wonderfully complex question that requires a complex answer.
There are a wide variety of infant formulas on the market. Up until now there were generally three different types of infant formulas to choose from. The three major types were cow milk protein-based formulas, soy-based formulas, and protein hydrolysate formulas.
Most of the formulas you’ll find are cow milk protein-based formulas. Many babies may tolerate this type of formula, however, those with milk protein allergies or other intolerances will require an alternative to cow milk protein-based formulas.
Soy-based formulas are an alternative for babies who are lactose intolerant or have a milk protein allergy. It is important to note that some babies who are allergic to cow’s milk may also present an allergy to soy and will require an alternative to both cow milk and soybean based formulas.
Protein hydrolysate formulas include protein that has been broken down (hydrolyzed) into smaller pieces which makes them tolerable for babies who are allergic to regular cow’s milk or soy-based formulas. These formulas can be very expensive and have a strong odor.
Goat’s milk formula is another alternative to cow milk protein based formulas that has gained popularity in recent years. Making the shift from cow’s milk formula to goat’s milk formula may not solve the allergy or intolerance problems for your baby.
Goat’s milk formula contains many of the same proteins that cause allergic reactions, and goat’s milk contains only slightly less lactose than cow’s milk. For babies with a severe sensitivity to lactose, goat’s milk can still trigger unpleasant symptoms related to lactose intolerance.
Else’s infant formula will offer a whole food, plant-based alternative to cow’s milk, soy, and hydrolysate formulas for a “cleaner,” safer product for your baby.
