When I worked at a factory that made baby formula, we made our name brand version and also the version that went to Walmart. Our name brand stuff had the modern,most recently developed formulation for maximal nutrition and flavor. The walmart labeled stuff was made using a recipe that was two iterations old. Still ok, not the best or most current. Both made in the same factory by the same people. Both probably healthful for your baby (assuming I didn't let a bad batch slip through in my job in Quality Control/Assurance), but not quite equivalent.
