Baby formula upgrade: could lactoferrin close the gap with breast milk?

This study looked at whether adding a protein called lactoferrin (found in breast milk) to infant formula can boost immune function and reduce infections in formula-fed babies. It also tested if lowering the iron level in formula is safe and still supports healthy development. About 252 healthy infants were enrolled, with some getting standard formula, some getting formula with added lactoferrin, and a breastfed group as a reference. The goal was to see if these changes make formula more like breast milk.
