Protein lactoferrin is present in
human body and it is found in certain body fluids such as saliva, breast milk and
urine. The main function of protein lactoferrin is to bind with and transport
iron in the body. When an infant absorb iron in breast milk, protein
lactoferrin attaches to any of the extra iron that the infant does not absorb
and stops it from allowing harmful pathogens such as bacteria to grow in the
baby's gastrointestinal tract. Thus, protecting babies from illness and
infections.
