HiPP Hypoallergenic formulas are specially developed for babies with allergies and food sensitivities. The milk proteins in these formulas are broken down into smaller pieces (hydrolyzed) to minimize the risk of allergic reactions. In addition, hypoallergenic formulas do not contain starch, as allergy-prone babies often experience digestion issues. Formulas free of starch are easily digestible, making them ideal for sensitive tummies.
