Lactoferrin: A Protective Protein Found in Milk
Lactoferrin is a naturally occurring protein most abundant in human colostrum and milk, where it plays a key role in the body's first defense system. It binds iron, making it less available to certain bacteria, and is recognized for its importance in supporting the health benefits of breast milk. This multifunctional protein is also found in lesser amounts in cow’s milk and other bodily secretions.
