Lactoferrin is widely used in the food and beverage industry as a natural preservative and nutritional enhancer. It is added to infant formula to mimic the immune-boosting properties of breast milk, promoting healthy growth and development. In the healthcare sector, lactoferrin is utilized in dietary supplements for its antimicrobial, anti-inflammatory, and immune-modulating effects, helping to combat infections and support overall health. It is also incorporated into skincare products for its antioxidant properties, which help protect the skin from damage and improve its appearance. Additionally, lactoferrin is being researched for its potential role in managing chronic diseases and improving gut health due to its ability to regulate gut microbiota and enhance intestinal barrier function.
