Each pack contains 180 capsules and provides a 30-day supply at the recommended dosage.
Why we have included Modern Native in the PraveBio.cz range
Modern Native is a Dutch brand specialising in organ-based food supplements. It grew from founder Jeroen van Straaten’s personal experience with strength training, a limited diet and a return to foods traditionally eaten according to the nose-to-tail principle.
The brand uses organs from grass-fed Dutch cattle, freeze-dries them and fills them into beef gelatine capsules without fillers. It is not an organic-certified brand. Its main strengths are traceable sourcing, relationships with local farms, glass packaging and gentle organ processing without unnecessary additives.
Grass-fed beef spleen – freeze-dried organ meat in capsules
Grass-fed beef spleen provides a less commonly eaten organ in capsules, without the strong taste, kitchen preparation or inconsistent portioning. A daily dose of 6 capsules provides a precisely measured amount of spleen powder, making it easier to include beef spleen when fresh organ meat is not a regular part of the diet.
- For: adults and physically active people who prefer organ meat in capsules.
- Characteristics: a single-organ supplement from grass-fed Dutch cattle.
- Naturally occurring components: haem iron, vitamin C, vitamin B3, vitamin B12, selenium and alkylglycerols naturally found in beef spleen.
- Free from: fillers, sweeteners, flavourings, gluten, soya and plant-based capsules.
- Dosage: 6 capsules daily, preferably with meals and plenty of water.
Unlike standard mineral supplements, this is not an isolated iron compound. It contains a whole animal-derived ingredient, which is freeze-dried, ground and filled into beef gelatine capsules. Compared with multi-organ blends, it has a narrower and clearer focus: beef spleen only.
The simple formula contains no additional organs, herbs or isolated minerals, making both the chosen ingredient and dosage easy to understand. The emphasis is on precisely measured capsules, traceable Dutch sourcing and a more neutral way to take spleen without the sensory intensity of fresh organ meat.

Edible organs differ from muscle meat in their nutritional profile. A review published in the PubMed database describes marked differences between individual organs and variations in selected micronutrients compared with standard muscle meat.
Beef spleen is also discussed in scientific literature in relation to its iron and ferritin content. This provides nutritional context for the organ ingredient rather than a standalone health claim.
Consumer research into edible beef organs suggests that acceptance is affected by taste, appearance and the method of preparation. The capsule format mainly offers practicality and sensory neutrality.

Which Modern Native supplement should you choose?
Modern Native supplements differ mainly in the type of animal-derived ingredient and the breadth of the formula. For a clear comparison, it helps to distinguish between single-organ products, multi-organ blends and fermented animal-derived supplements.
Individual organs in capsules provide a focused way to include a particular ingredient. Beef liver, heart, kidneys and bovine glands each have a different nutritional profile, so the choice depends on the specific formula.
Multi-organ blends combine a broader range of animal tissues in one dose. They offer a more general form of organ-based nutrition by combining several organs without focusing on one particular tissue.
Specialised organ supplements have a narrower focus. Bovine glands with liver fall into this category, combining reproductive glands and liver in a precise ratio without herbs, sweeteners or isolated minerals.
Fermented animal-derived supplements extend the Modern Native range beyond organ meat. These include kefir capsules, based on a traditional fermented food.
Why choose Modern Native
Brand background: Modern Native was established in the Netherlands in response to a simple issue: organ meat is a traditional nutrient-dense food, but most people no longer prepare it regularly. Founder Jeroen van Straaten began exploring organ meat after his experience with strength training, a limited diet and a search for nutrition based on clearly identified ingredients rather than anonymous blends.
Nose-to-tail principle: The brand follows the view that a quality animal should not be reduced to muscle meat alone. Organs are part of the traditional use of the whole animal, and Modern Native provides them in a precisely measured, easy-to-store format that is straightforward for customers who do not want to prepare organs in the kitchen.
Relationships with Dutch farms: The ingredients come from grass-fed Dutch cattle. The brand has long-standing relationships with local partners, including Zorg & Natuur, Vlees van Ons and Reestdal Rund. A shorter supply chain supports traceability, the freshness of the raw ingredient and less reliance on anonymous high-volume sources.
Gentle processing: The organs are freeze-dried, ground into powder and filled into beef gelatine capsules. The brand avoids fillers, flavourings and plant-based capsules that would unnecessarily change the character of the animal-derived supplement. The result is a simple formula that is clear from the label.
Glass rather than plastic: Modern Native uses glass jars, limiting contact between the capsules and plastic while protecting the contents from light. This detail reflects the brand’s approach: practical decisions that affect storage quality rather than prominent promises.
Who the brand is not for: Modern Native is neither vegan nor certified organic. It is for customers who prefer whole animal-derived ingredients, traceable sourcing and concise formulas over sweetened powders, flavoured blends or long ingredient lists.

What is haem iron?
Haem iron is a form of iron typical of animal-derived foods. In beef spleen, it comes from the whole organ ingredient rather than an isolated mineral salt.
What should I consider when addressing iron levels?
Low iron and anaemia are medical matters. A food supplement is not a treatment for or means of preventing anaemia. Seek medical assessment for laboratory-confirmed iron deficiency or tiredness of unknown origin.
Can I combine it with iron or a multivitamin?
When combining products, consider the total daily intake of iron, selenium and other micronutrients. Consult a doctor when taking iron, a multivitamin or medication at the same time.
What role does vitamin C have in this supplement?
Vitamin C occurs naturally in beef spleen. It is mentioned only as part of the natural complex of nutrients, without reference to authorised EFSA health claims.
What are alkylglycerols?
Alkylglycerols are lipid substances naturally found in spleen tissue. They are mentioned only as part of the spleen’s natural profile, without a health claim.
Can I take it during pregnancy or breastfeeding?
Consult a doctor before use during pregnancy, breastfeeding or when planning a pregnancy. This is because it contains an animal-derived organ ingredient and the total intake of iron and other micronutrients needs to be considered.

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.
