Lactoferrin is a multifunctional glycoprotein found naturally in mammalian milk, tears, saliva, and other bodily secretions. It plays a key role in regulating iron absorption and immune function. Lactoferrin exhibits broad-spectrum antimicrobial activity by binding free iron, which inhibits the growth of bacteria and fungi. It also possesses antioxidant, anti-inflammatory, and prebiotic properties, supporting gut health and overall immunity. Due to these benefits, it is widely used in dietary supplements, infant formulas, and functional foods.
