NAN H.A. is the hypoallergenic formula, which is easier to digest and helps to reduce the risk of allergies. NAN Optipro is the usual cow's milk formula. If your baby has no known allergies or issues, good to start with NAN Optipro first as it's cheaper and does not have the bitter taste that most parents said is present in H.A. versions
How old is bb? Does he have allergies? If doesn’t start on regular formula and need no go on hypo allergic milk. Try a few brands if you like. I heard Friso is good for digestion!
My PD recommended HA cause my baby have ecezma. Otherwise I think just get the Nan Pro will do.
