Why local Dutch farms?
- This business provides livelihoods for local environmentally conscious farmers.
- It creates jobs in this sector and thus supports the emergence of more organic farms and livestock.
- Where there is greater demand, there will be greater supply – in the long term, this supports the availability of quality animal products.
More local eco-farmers mean less mass production and happier Dutch cattle.
- Money spent on farms stays in the local economy, creating a domino effect and generating more jobs.
- Shorter distribution chains reduce unnecessary transport and carbon footprint.
- Where livestock is raised according to organic farming standards, there is healthier soil and a richer ecosystem.

FAQs
Is this supplement suitable for lactose intolerance?
The product contains kefir and colostrum from cow's milk, but due to fermentation and natural enzymatic activity (especially the presence of lactase in kefir), many people with lactose intolerance tolerate it without issues.
Colostrum also has a low lactose content. We recommend starting with a lower dose and monitoring the body's reaction. For severe intolerance or allergy to cow's milk protein, the product is not suitable.
What makes the men's mix special?
The supplement combines five nutrient-rich foods into one capsule – beef liver, testicles, oysters, kefir, and colostrum. These ingredients are gently freeze-dried and retain their natural nutritional value.
Liver and oysters are rich in B vitamins, zinc, copper, and iron. Testicles provide specific peptides and enzymes. Kefir and colostrum complement the mix with enzymes, lactic fermentation bacteria, and immunoglobulins.
Is this supplement halal?
The gelatin capsules used in this supplement are halal certified, as are the parts containing kefir and colostrum.
However, the organ components (liver, testicles, oysters) do not come from animals slaughtered according to halal rules, and therefore the product as a whole is not halal certified.
Who is behind the Modern Native brand?
Modern Native is a Dutch brand based on the idea of returning to real nutrition from natural and traditional sources. It produces dietary supplements from whole animal foods, without additives, fillers, or synthetic substances.
The range includes products such as freeze-dried liver, testicles, colostrum, or kefir – animal ingredients come from ethically managed farms, and the product composition always reflects simplicity, functionality, and high nutritional density.
What is the shelf life of the product?
The freeze-dried supplement has a shelf life of 2 years from the date of freeze-drying. A shorter date may be indicated on the label depending on the storage time at the manufacturer or distributor. Store in a dry, cool, and dark place, out of reach of children.
What allergens does this product contain?
The product contains shellfish (oysters) and lactose from dairy components (kefir and colostrum). People with allergies to these substances should use the supplement only after consulting a specialist.

Our ancestors lived differently from us. Traditional societies have been eating organ meat for centuries. They did it for a reason. Intuitively, they knew it was good for them. They knew that organ meats were the source of the most important nutrients. Similarly, in nature many predators go after organ meat first and muscle meat second.
We hardly eat organs these days. It's an ancient tradition that has faded away. Modern Native's mission is to bring the wisdom of our ancestors back to the modern world for optimal health, strength and happiness.
There is no organ meat like meat
Not all organs are the same. When looking for quality (organ) meat, it is important to check several points:
- 100% grass-fed cattle
- Without hormones
- Pesticide and GMO free
- Animals live stress-free and completely in the wild
The term "grass-fed" doesn't tell the whole story. The cow may be partially outside in the summer eating fresh grass, while most of the time she is in the barn and fed concentrate. 100% grass-fed, that's the Modern Native way of doing things. They only work with farmers whose cattle meet the above points. The organs are obtained from cattle in the Netherlands.

Why local cattle?
- It maintains the health of local natural farmers and creates jobs in the industry, thus creating more natural farmers in the Netherlands.
- Where there is more demand, there will be more supply. This will eventually allow the price of quality meat, including organ meat, to fall.
- More local natural farmers means fewer traditional herds (mass production) and happier cattle.
- Money spent on local farms stays in the economy, which has a domino effect and creates more jobs.
- Shorter distribution chains reduce unnecessary transport.
- When there are more natural livestock, healthier soil is created.
- Naturally grazing cattle return nutrients to the soil through the urine and manure they excrete.

Method for Modern Native accessories
- It comes from 100% grass-fed cattle.
- No hormones.
- Pesticide and GMO free.
- The animals live stress-free and completely in the wild.
Why eat organ meat?
Beloved by our ancestors
Traditional peoples, Native Americans, and ancient ancestors believed that consuming the organs of a healthy animal would promote the health of the individual's organ. They ate "from head to tail", i.e. everything from the animal, because they intuitively knew how nutritionally rich the meat from the organs was.
