French colostrum of animal origin, from cows raised on small family farms (as is the case 100m from our office).

Colostrum is the "milk of the first days", before milk production, and therefore extremely rich in protein. High quality, it is harvested within the first 12 hours for maximum immunoglublin density. Siho colostrum has an exceptional nutritional content: 50% IgG as well as many other nutrients: IgA, IgE, IgM, Il-1, Il-6 and Il-10, growth factors IgF-1 and IgF-2 , PRP, Lactoferrin or even l-carnitine.

All this gives it exceptional nutritional qualities, helping natural defenses and digestion.

Guaranteed without pasteurization, it is nevertheless free of bacteria, germs and other pathogens. Thanks to this unique process, it keeps all its initial qualities.

From dairy cows, it contains lactose as well as casein, but in small quantities. Thanks to the lactase enzymes that help digest milk, there should be no intolerance when ingesting it.

Intestinal health: Promotes a healthy intestinal flora and the normal functioning of the entire digestive tract.

Growth Factors: Growth factors naturally found in colostrum can promote the growth of new cells for healthy skin, bones, muscles, nerves and cartilage.

Immune response: improves your body's immune response in case of aggression
Endurance: May improve endurance and muscle growth after strenuous exercise, at approximately 20 grams per day.

100% French colostrum, from family farms, part of which is organic. The cows are raised without antibiotics and fed on grass.

Origin: regions of northern France (Hauts-de-France, Normandy, Brittany), including one 100m from our offices :)


Derived from milking in the first 24 hours after giving birth, Siho colostrum is offered to you in powder form. Its consistency is the same as powdered milk. It is therefore very easy to dose. It is exceptionally rich in immunoglobulin (50% IgG).


1 to 4 teaspoons according to your needs, to be diluted in a cold drink at any time of the day. Once the powder is in the glass, add water and stir immediately. Wait a minute, stirring occasionally, and the colostrum will be completely dissolved.

Proline-rich polypeptides (PRPs)

PRPs act systemically, modulating the immune system so that it can better respond to its needs.

Immunoglobulins (IgG, IgA, IgE, IgM, IgD)

Immunoglobulins are antibodies. They play an essential role in maintaining a healthy immune system and digestive tract.

Naturally occurring growth factors

Growth factors are peptides that activate or deactivate the production of specific proteins in target cells. They contribute to the growth, development and maintenance of a healthy intestinal wall.


Lactoferrin is an iron-binding protein found in most immune cells. Its receptors are found on most immune-functioning cells, including lymphocytes, monocytes, macrophages and platelets.

I often get asked if there was a particular product that helped me get back to normal life. To this question I answer that there was a before and an after: the one where I consumed colostrum. Before that, my digestion was catastrophic and my stomach aches very frequent, unless on an ultra strict diet. I dreamed of being able to eat everything, of having no more pain and no longer being tired. After a few weeks of taking bovine colostrum daily, my gut health improved greatly. I was then able to quickly return to a varied diet and a normal life.

I dreamed of offering you this food from responsible farms where antibiotics are banned and where the immunoglobulin level is exceptional. The quest was long and I am proud to be able to offer you today such a qualitative product that meets the highest safety and quality standards.

🍃 - "Always", that's what Sophie said when asked how long she had had a stomach ache. Here the past is used because his stomach problems are, precisely, in the past. In a few days she noticed noticeable improvements, at the rate of 3 teaspoons a day. A few weeks later she left with her family for the mountains. Who says change of habit says change of diet and, very often in people with a capricious intestine, it does not pass. Except that this time no problem! And the following times either.

🍃 - Cédric regularly suffers from episodes of diarrhea, which complicates his life. After having consulted specialized doctors, passed several colonoscopies which did not detect any problem and tried dozens of food supplements, he tried Siho bovine colostrum. Skeptical at first, he saw his digestion gradually improve after two weeks, taking two teaspoons on an empty stomach in the morning. Since then he consumes it every day and has a much better transit. Without being perfect because he himself admits abusing croissants and pizzas 🙂
