HA formula by HiPP is a their Combiotic subcategory for hypoallergenic formulas. They are suitable especially for children who are at risk of allergies and cannot be breastfed. In HA’s organic formula the proteins are broken down into smaller pieces (partially hydrolyzed), therefore, the baby’s organism perceives those modified amino acids as less as non-HA based formulas. HA products are available in three different formula stages (Pre, 1, 2) and thus offer an alternative for children at risk of allergies at any age. As HA Organic formula is also made from cow's milk, children with cow's milk allergy or lactose intolerance should not drink it. Please talk to your pediatrician before switching to hypoallergenic formula.
