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 interest in the traditional use of animal-derived ingredients and the nose-to-tail approach.
The organs are freeze-dried and filled into beef gelatine capsules without fillers. This is not an organic brand in the certification sense; its main strengths are traceable sourcing, relationships with local farms, glass packaging and gentle organ processing without unnecessary additives.
Grass-fed beef testicles with liver – freeze-dried organs in capsules
Grass-fed beef testicles with liver is a food supplement containing 50% freeze-dried beef testicles and 50% freeze-dried beef liver. The capsule format makes it easier to include organ meat without its distinctive taste, kitchen preparation or variable portions. A daily serving of 6 capsules provides 3000 mg of organ powder, equivalent to approximately 15 g of fresh organ meat. A pack of 180 capsules provides a 30-day supply at this dosage.
- For: adults who prefer organ meat in capsules without cooking or a distinctive taste.
- Characteristics: a blend of testicles and liver from grass-fed Dutch cattle.
- Naturally occurring nutrients: zinc, selenium, vitamin A, vitamin B3 and vitamin B12 found in the organs used.
- Free from: fillers, sweeteners, flavourings, gluten, soya and plant-based capsules.
- Dosage: 6 capsules daily, preferably with a meal containing fat because of the fat-soluble vitamins.
Unlike a conventional multivitamin, this is not an isolated blend of synthetic substances. The nutrients come from whole animal-derived ingredients, which are freeze-dried, ground into powder and filled into beef gelatine capsules. Compared with a five-organ blend, this formula has a narrower focus: testicles and liver, two clearly defined animal-derived ingredients.
The simple formula contains no other organs, herbs or isolated minerals, making the source and ratio of the ingredients easy to understand.

Which Modern Native supplement should you choose?
Modern Native supplements mainly differ in the type of animal-derived ingredient used and the breadth of the formula. When choosing, it helps to distinguish between single-organ products, multi-organ blends and fermented animal-derived supplements.
Individual organs in capsules provide the clearest way to work with a specific ingredient. Beef liver, heart, kidneys and testicles have different nutritional profiles, so selection should be based on the ingredients rather than a general impression of the category.
Multi-organ blends bring a broader range of animal tissues into one serving. They offer a straightforward introduction to organ-based nutrition without choosing a single tissue.
Specialised organ supplements use a narrower selection of ingredients. Beef gallbladder with liver falls into this group, combining bile-associated animal tissue with nutrient-dense liver in capsules without sweeteners, flavourings or plant-based capsule shells.
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 origins: Modern Native was founded in the Netherlands in response to a simple issue: organ meat has a long history as a traditional food, but most people no longer prepare it regularly. Founder Jeroen van Straaten became interested in organs after his experience with strength sports, a restricted diet and a search for food that did not rely on anonymous blends.
Nose-to-tail approach: The brand works on the principle 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 presents them in a precisely measured, easy-to-store format that is also accessible to 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 works with local partners over the long term, including Zorg & Natuur, Vlees van Ons and Reestdal Rund. A shorter supply chain supports traceability, the freshness of the raw ingredients 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 alter the animal-derived nature of the 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 bold 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 to sweet powders, flavoured blends or long lists of additives.

FAQ
What is Grass-fed beef testicles with liver for?
It is a food supplement made from freeze-dried beef testicles and liver for adults who prefer organ meat in capsule form. Zinc contributes to normal fertility and reproduction and the maintenance of normal testosterone levels in the blood. Selenium contributes to normal spermatogenesis.

How do I take the capsules?
The recommended daily serving is 6 capsules daily. Take the capsules together or divide them throughout the day. Take them with meals where this is more comfortable.

Do I need to start with the full serving?
With organ-based supplements, begin gradually with 1–2 capsules daily, for example, before slowly increasing the amount. This makes it easier to assess individual tolerance.

When can I assess whether the supplement suits me?
No specific timeframe or result can be promised for an organ-based supplement. Individual experience varies according to diet, sleep, physical demands, health and consistency of use. For your own assessment, take it regularly for several weeks and monitor your individual tolerance.

How much organ meat is equivalent to the daily serving?
A daily serving of 6 capsules provides 3000 mg of freeze-dried organ powder. This is equivalent to approximately 15 g of fresh organ meat.

What is the ratio of beef testicles to liver?
The formula contains a precise ratio of 50% freeze-dried beef testicles and 50% freeze-dried beef liver. The daily serving provides 1500 mg of testicles and 1500 mg of liver.

What does freeze-dried mean?
Freeze-drying removes water from organ meat without conventional heat drying. The result is a dry organ powder that can be filled into capsules.

What does grass-fed mean?
Grass-fed means that the beef organs come from cattle fed on grass. In this case, the ingredients come from Dutch pasture-based farms.

Where do the ingredients come from?
The beef testicles and liver come from grass-fed Dutch cattle. A shorter and more traceable supply chain is particularly important for animal-derived supplements because it supports control of the source material.

How does it differ from a five-organ blend or a men’s complex?
Unlike a five-organ blend, this formula contains only two ingredients: 50% beef testicles and 50% beef liver. Compared with a men’s complex containing oysters, kefir and colostrum, it has a shorter formula without other food ingredients.

Are the capsules appropriate for vegans?
No. The formula is entirely animal-derived: beef testicles, beef liver and a beef gelatine capsule. The capsules are therefore not appropriate for vegetarians either.

Why is the capsule made from beef gelatine?
The beef gelatine capsule matches the animal-derived nature of the supplement. It also masks the distinctive taste of the organ powder and provides precise dosing without plant-based capsule blends.

Do the capsules have a strong taste or smell?
The capsules significantly reduce direct contact with the taste of the organ powder. A natural animal-derived aroma may be noticeable when the jar is opened, reflecting the ingredients used and the absence of flavourings.

Can I open the capsules and add the powder to food?
You can technically open the capsule, although the organ powder has a distinctive taste. Capsules provide a more practical way to take organ meat without the taste of fresh or dried organs.

Is it better to take the capsules with meals?
Taking them with meals is particularly appropriate because vitamin A is fat-soluble. This may also be more comfortable if taking them on an empty stomach does not suit you.

Can I divide the daily serving?
Yes. Take the daily serving of 6 capsules together or divide it between two meals, for example. Do not exceed the recommended daily dosage.

How do I calculate how long a pack will last?
Divide the number of capsules in the pack by the recommended daily serving of 6 capsules. A pack of 180 capsules, for example, provides 30 days at the recommended dosage.

Do the capsules contain gluten, soya or sweeteners?
No. The formula contains freeze-dried beef testicles, freeze-dried beef liver and a beef gelatine capsule. It is free from gluten, soya, sweeteners, flavourings and fillers.

Is the supplement certified organic?
No. This is not a certified organic food supplement. The focus is on animal-derived ingredients from grass-fed cattle, a simple formula and gentle freeze-drying.

How does it differ from fresh organs?
Fresh organs need to be purchased, stored and cooked. Capsules provide beef testicles and liver in a precisely measured, easy-to-store format without cooking or the distinctive taste of a prepared meal.

How does it differ from a conventional multivitamin?
A conventional multivitamin usually contains a blend of isolated vitamins and minerals. This formula is based on two whole animal-derived ingredients: freeze-dried beef testicles and liver.

Can I combine the capsules with other food supplements?
Yes, but consider your total intake of vitamin A, zinc, selenium and other micronutrients. Take particular care when also using multivitamins, retinol supplements or products with higher amounts of minerals.

Can I take the capsules while eating organ meat?
You can, but consider your total intake of organ meat. Liver naturally contains retinol and certain minerals, so a high long-term intake of fresh liver should not be combined with a full serving of organ capsules without professional advice.

Is the supplement appropriate for active adults?
Yes. For active adults, capsules can be a practical way to include organ meat without cooking or the distinctive taste of fresh organs. This is not a stimulant or pre-workout product; its significance comes from the nutritional profile of the organs used.

Is the supplement only for men?
The supplement is for adults. Its description is based on its ingredients and naturally occurring nutrients, for which approved claims relating to zinc and selenium may be used where their conditions of use are met.

Who should not take the supplement?
It is not for kids, vegans or vegetarians. Consult a doctor before use during pregnancy or breastfeeding, when planning a pregnancy, taking medication or managing a medical condition.

Is it appropriate during pregnancy or breastfeeding?
Consult a doctor before use during pregnancy, breastfeeding or when planning a pregnancy. This is primarily because of the natural vitamin A content in the form of retinol, which needs to be considered as part of your total intake when consuming liver.

Why is the vitamin A warning important?
Liver naturally contains vitamin A in the form of retinol. Consider your total vitamin A intake and do not combine several supplements containing higher amounts of retinol without professional advice, particularly during pregnancy, when planning a pregnancy or while taking medication.

What should I consider regarding zinc and selenium?
Zinc and selenium are naturally occurring minerals. When also taking other supplements containing zinc or selenium, monitor your total daily intake and do not exceed the recommended dosage of each product.

Which nutrients are typical of this formula?
Typical naturally occurring nutrients from the organs used include zinc, selenium, vitamin A, vitamin B3 and vitamin B12. Zinc contributes to normal fertility and reproduction, selenium to normal spermatogenesis and vitamin B12 to normal energy-yielding metabolism.

Why can the colour or aroma of the capsules vary?
This is a natural animal-derived ingredient without flavourings or colourings. Slight differences in colour, the shade of the powder or aroma may reflect the characteristics of each batch and are not unusual in organ-based supplements with simple formulas.

How should I store the capsules?
Keep them tightly closed in a cool, dry place and out of reach of young children. Protect the glass jar from direct sunlight and moisture.

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.
