Lactoferrin to strengthen the immune system

7 August, 2020

The World Health Organization today declares that there are still no specific vaccines or drugs that can defeat the coronavirus disease (COVID-19). However, many clinical trials are underway to search for medical scientific solutions to improve the chances of recovery and survival.

Before even reflecting on how to intervene in the course of the disease, it is of crucial importance to be able to act preventively and increase the immune system, creating an immunological barrier capable of protecting the upper respiratory tract, considered the main access route of the virus into guest.

Recent studies have shown that some components of human secretions are key elements of the immune system and act as a key barrier against viral injury.

What the research says

The research “Lactoferrin as Protective Natural Barrier of Respiratory and Intestinal Mucosa against Coronavirus Infection and Inflammation” conducted by the Roman universities Tor Vergata and La Sapienza and published in the “International Journal of Molecular Sciences” has highlighted the possible preventive role of lactoferrin.

Assuming that this glycoprotein is a component of the innate immunity of children and that it is a fact that the pediatric population has been the least affected by the coronavirus pandemic, the review set the stage for its use in supporting defenses. immune.

What is Lactoferrin

Lactoferrin is a multifunctional protein with recognized antimicrobial and antiviral properties, belonging to the transferrin family, capable of binding and transporting iron. It is found mainly in breast milk, especially in colostrum, saliva and tears, in neutrophil granulocytes, immune cells that defend the body from fungal and bacterial infections.

What are the functions of Lactoferrin?


The main activity of lactoferrin seems to be attributed to its ability to bind and retain iron, an important nutrient for potential pathogens that depend on it for multiplication and adhesion to the mucous membranes. The ability to damage the outermost layers of the cell membrane of some bacterial species should also be highlighted.


By binding to plasma membranes, lactoferrin prevents the binding between viral particles and target cells, blocking replication and infection in the bud, thus acting as an important preventive factor; this mechanism appeared effective against herpes simplex.


Lactoferrin is able to naturally stimulate the growth of bifidobacteria in natural killer cells, stimulate the activity of neutrophils and modulate the activity of inflammatory cytokines. It is therefore an ideal support for the entire immune system.

There is no doubt that this substance is essential for the human body and the immune system in the fight against viruses and other microbes.

Lattoferrina 200 Immuno

PromoPharma® research and development laboratories, making use of the scientific studies of these authoritative Italian universities, have decided to formulate a new supplement: Lattoferrina 200 IMMUNO.

Lattoferrina 200 IMMUNO contains 200 mg of lactoferrin, in practical buccal sticks, it is taken once a day, pouring the contents of the stick directly into the mouth.

When to take Lactoferrin 200mg:

  • Low low immune defenses
  • Bacterial infections
  • Viral infections
  • Iron deficiency anemia
  • Gastrointestinal disorders
