What is Colostrum?

Colostrum (first milk) is the first milk of the mother cow and is produced in a highly concentrated form in the first 72 hours after birth. Unlike humans, calves see the light of day without an innate immune system. It is only through maternal Colostrum that they are provided with a secure protection for a healthy cow life. This wealth of immune competence is unique in nature.

For the production of our LACsell® Colostrum products, the Colostrum is only obtained from the 1st and 2nd milking. This guarantees the highest concentration of over 400 bioactive substances. For our LACsell® Colostrum products, we only use surplus Colostrum that the newborn no longer needs, because, of course, the health of the calf always comes first.

Colostrum, the building block of life

Our main interest is in the numerous immune factors found in Colostrum. These are bioactive messenger substances that can directly influence immunological processes. In particular, these are special antibodies (immunoglobulins), but growth factors, hormones and cytokines also play a major role. Additionally, of course, Colostrum also contains numerous vitamins, enzymes and minerals, as well as all amino acids.

We would like to explain these bioactive messengers to you in detail.

Antibodies = Immunoglobulins

Immunoglobulins – proteins produced as a specific response of the immune system to the invasion of pathogens. These antibodies can neutralize or label bacteria, viruses, allergens, etc. on their own, so that as a result other immune-competent helper cells can take over this work.

* IgG – antibodies make up the largest proportion with approximately 80%. Among other things, they are responsible for the defense against invading bacteria or viruses. Antibodies neutralize unknown microorganisms.

* IgA – antibodies protect the mucous membranes in the nose, throat and intestines from bacterial and viral attacks in a direct line.

* IgD – antibodies stimulate B-cells to produce very specific antibodies.

* IgE – antibodies control allergic reactions, among other things.

Growth factors

Growth factors are special messenger substances that modulate cell metabolism by transmitting information from one cell to another. On the one hand, they intervene directly in cell division and the differentiation of stem cells; on the other hand, they also regulate a wide variety of intracellular processes.

Bio-identical hormones

Hormones (an ancient Greek term that could also be translated as “drive”) are intra-secretory glandular substances that ‘activate’ organs and metabolism in the best sense.

Proline-rich polypeptides (PRP)

PRP have a regulatory effect on the immune system via the thymus gland. They can stimulate a weakened immune system as well as calm an allergic overreaction. Polypeptides support the functions of our brain activities and contribute to mental stabilization.


Lactoferrin (LF) is a strong iron-binding protein and is found in many body fluids, and also in white blood cells. To this end, Lactoferrin has both antiviral and antimicrobial properties.


Cytokines are special proteins with regulatory properties. They serve to control the body’s immune response to pathogens. Interleukins are also responsible for communication among immune cells so that targeted defense responses can be coordinated.
