Lactoferrin is a core constituent of the human body’s immune system, carrying potent antimicrobial properties that kill both bacteria and fungi, and forming a critical component of innate immune defense that primarily acts across mucosal surfaces. Most notably, it provides targeted antibacterial protection for human infants. It can interact with DNA, RNA, polysaccharides and heparin, and many of its key biological functions are activated when it forms stable complexes with these ligand substances. As a professional manufacturer of Lactoferrin Protein, China Extract Warehouse has long been dedicated to supplying premium grade Lactoferrin powder to clients all over the world at highly competitive, fair pricing. For parties seeking long-term collaborative partnerships, complimentary product samples are available upon request.

Application of Lactoferrin Protein
Lactoferrin (LF), also known as lactotransferrin (LTF), is a multi-functional protein belonging to the transferrin family. It is a globular glycoprotein with a molecular mass of roughly 80 kDa, that is widely present in various secretory fluids such as milk, saliva, tears and nasal mucosal excretions. It also exists in the secondary granules of PMNs, and is secreted by some specialized acinar cells. It can be purified directly from milk, or manufactured via recombinant biotechnological processes. Human colostrum (widely called "first milk") has the highest natural concentration of this protein, followed by regular mature human milk, then cow milk which contains approximately 150 mg/L of the active ingredient.
Benefits of Lactoferrin Protein
Lactoferrin is one of the core component proteins that make up the human innate immune system. Beyond its primary function of binding and transporting iron in the body, it also delivers a wide range of functional attributes including iron-targeted antibacterial action, antiviral effects, anti-parasite activity, catalytic properties, cancer prevention and anti-tumor action, anti-allergy support, and radiation protection effects. Its most widely verified key functions are as follows:
- Broad-spectrum antimicrobial activity
- Potent antiviral performance
- Effective antifungal action
- Promotes iron absorption via milk protein receptor pathways
- Provides supportive benefits for cystic fibrosis related management
