Lactoferrin is an iron transporter protein that is a natural part of the human defense system. It is a first line of defense found in various secretions such as saliva, tears and milk, and it is important for fighting infections and stimulating the immune system. It also improves nutrient absorption and stimulates bone growth. Its effects on the immune system help to fight infections, abnormal cellular growth and modulate the immune system to avoid excessive inflammation.
Since iron is an essential nutrient for harmful bacteria, lactoferrin’s iron binding ability restricts pathogenic growth. It also prevents harmful bacteria from attaching to intestinal walls. One of lactoferrin’s breakdown products inhibits viral access to cells. Not all bacteria are harmful, and some are essential to health. Lactoferrin is an important factor for the proper composition of healthy bacteria in the gut.
Lactoferrin’s roles in helping the body fight infections, balancing the immune system and maintaining healthy cell growth, bone health, and gastrointestinal health make it a very important nutrient for overall health. It is extremely resistant to degradation in the gastrointestinal tract, making it an effective supplement.
