Lactoferrin

Lactoferrin is a naturally occurring glycoprotein found in milk and other bodily secretions, most commonly supplemented in its bovine-derived form. Research suggests it plays a multifaceted role in supporting immune function, as it can bind iron and modulate inflammatory responses while also demonstrating antimicrobial activity against certain bacteria, viruses, and fungi. Studies indicate that lactoferrin may contribute to gut health by promoting the growth of beneficial bacteria such as bifidobacteria and lactobacilli, which is why it is often grouped alongside prebiotics despite being a protein rather than a fiber. Additionally, its iron-binding properties have drawn interest for their potential role in enhancing nutrient absorption, particularly in populations where iron status is a concern. While the body of evidence continues to grow, lactoferrin remains an intriguing area of nutritional research worth following.
