ativa HA is a powdered milk suitable for infants from birth when they can not breast-feed alone. Nativa HA offers the necessary amount of protein and all the necessary nutrients to meet the nutritional needs of an infant of this age. It is indicated for infants with an increased risk of allergic reaction to cow's milk (eg because another family member has developed an allergy). If your baby has already been diagnosed with a cow's milk protein allergy, do not use Nativa HA without consulting your pediatrician.
