Is lactoferrin a protein?

Lactoferrin is a special type of protein originating from milk, especially abundant in colostrum, and is a member of the transferrin family. Lactoferrin is an iron-containing whey protein and belongs to the category of proteins. This protein not only has highly efficient iron-binding capacity but also performs multiple important biological functions in the body, such as enhancing the activity of immune cells and promoting the absorption and utilization of iron, thereby helping to maintain immune health and iron metabolism balance.

Lactoferrin has various biological functions in the human body, including involvement in iron transport and storage, regulation of immune responses, antimicrobial effects, and promotion of intestinal health. Lactoferrin is mainly present in the milk of mammals, particularly at higher levels in colostrum. Therefore, lactoferrin is commonly used in infant formula, health supplements, and pharmaceutical products. For populations needing additional iron supplementation or immune support, such as infants, pregnant women, and the elderly, lactoferrin is a safe and effective option. For specific health conditions or disease treatments, lactoferrin should be used appropriately under the guidance of a physician.
