Whey protein lactoferrin powder can play a strong role in promoting iron absorption through lactoferrin because the binding rate of iron and lactoferrin is very high, and whey lactoferrin supplementation can bind iron well and then transport it to the body like a ship, thus playing a strong role in correcting iron deficiency anemia. At the same time, whey lactoferrin competes with pathogenic bacteria to inhibit iron ions. When iron ions from pathogenic bacteria are captured by whey lactoferrin, the pathogenic bacteria lose their ability to cure the disease due to iron deficiency, so whey lactoferrin plays a very strong role in improving infectious diseases, especially bacterial infections such as pneumonia and enteritis.
