LactoferrinBestimmungen

LactoferrinBes... is not a standard term in scientific literature, and it may be intended to refer to lactoferrin-based products or derivatives. This article provides a concise overview of lactoferrin and how related lactoferrin-based formulations are viewed in research and industry.

Lactoferrin (LF) is a glycoprotein of the transferrin family found in mammalian milk and other secretions, as well as in neutrophil granules. It has a molecular weight of about 80 kDa and exists in iron-free (apo) and iron-bound (holo) forms. LF binds ferric iron with high affinity, playing a role in iron transport and in limiting microbial growth by iron sequestration.

In addition to iron handling, lactoferrin participates in innate immunity. It exhibits antimicrobial activity against a range of bacteria, fungi, and some viruses, through iron withholding and direct interactions with microbial membranes. LF also modulates inflammation, guides immune cell function, and can support gut mucosal integrity and the composition of the intestinal microbiota.

Applications and uses: In industry, lactoferrin is used as a functional ingredient in foods and dietary supplements, particularly bovine LF, and is added to infant formulas, nutrition products, and some oral care items. It is also explored in pharmaceutical and cosmetic contexts, including as a drug delivery carrier and in antimicrobial coatings. In research, LF serves as a tool for studying iron metabolism, immune responses, and host–pathogen interactions. Lactoferrin-based formulations may refer to products that use LF as an active component, a carrier, or a bioactive modifier.

Safety and regulation: LF is generally well tolerated in many products, but regulatory status depends on the source (bovine, human, or recombinant) and intended use. Individuals with milk protein allergies should exercise caution.
