NatuGena Copper – High-dose combination of three copper compounds: gluconate, bisglycinate and citrate. MCT powder is used as a carrier to support optimal copper bioavailability. The capsules are free from excipients, colourings and additives, and made in Germany. 90 vegan capsules for a 3-month supply.

  • Copper complex: Contains copper bisglycinate, copper citrate and copper gluconate
  • High-strength formulation: 2 mg of pure copper per capsule
  • Copper gluconate: A fruit acid chelate with gluconic acid, well absorbed by the body
  • Copper bisglycinate: Bound to the amino acid glycine, making it particularly stable and efficiently available
  • Copper citrate: Well tolerated and bioavailable; its mildly alkaline character makes it especially gentle on the stomach
  • Made in Germany: Exceptional purity and bioavailability for optimal nutrient uptake

Copper is an essential trace element needed only in small amounts. However, there may be times when the body requires more, such as during particular life stages or under specific conditions. Our copper complex combines three forms of copper in an optimally balanced ratio: copper bisglycinate, copper citrate and copper gluconate. Each form contributes its own unique properties to copper metabolism. Just as copper is never found in isolation in food, this formula offers diverse forms to support efficient and comprehensive absorption.

What does copper do in the body?

Copper is vital for the maintenance of connective tissues, normal pigmentation of skin and hair, and for the proper functioning of the immune and nervous systems. It also supports energy metabolism, contributes to iron transport in the body, and protects cells from oxidative stress.

What is the benefit of combining three copper sources?

Just like in nature, copper does not appear in a single form. This complex mirrors that variety by including multiple organic compounds.

  • Copper bisglycinate, bound to the amino acid glycine, provides high bioavailability.
  • Copper citrate, a mildly alkaline salt of citric acid, is well tolerated and absorbed without disrupting stomach acidity or intestinal flora.
  • Copper gluconate, a fruit acid chelate with gluconic acid, is also known for its excellent absorption.

Quality

  • No separating agents, binding agents or colourants
  • Free from genetic engineering, nanoparticles and animal testing
  • Hypoallergenic and sensitive formulations (e.g. free from lactose, soya and gluten where possible)
  • Ultra-pure, plant-based coating agents (HPMC) and food-safe, light-protected containers
  • Free from unwanted additives such as PEG, silicon dioxide, magnesium stearate & titanium dioxide
  • Premium raw materials from pure substances
  • Regular, independent testing for harmful substances
  • Production in accordance with German quality standards (GMP, HACCP, ISO 9001)

Vitamin C – The Classic Choice for Our Immune System and Its Forms of Administration

It’s hard to imagine daily life without vitamin C, and it’s often the first thing people mention when it comes to supporting the immune system. But there’s much more to this well-known nutrient than just a supplement for the cold season. From its historical beginnings on the high seas to cutting-edge technological developments, our understanding of its absorption and effects has steadily deepened. A look at its history and the various modern forms available reveals just how versatile this vitamin truly is.

FAQ

Most of our capsules can be opened without any concerns. The contents can be stirred into yogurt, plant-based yogurt, applesauce, smoothies, or juice, for example.

One of the reasons we encapsulate the ingredients is to keep their sometimes intense natural taste and smell as neutral as possible. When opened, the taste and smell may therefore be more noticeable.

Did you know? Our capsules can be easily opened by gently twisting them.

Please do not open: enteric-coated capsules

For certain bacterial and enzyme products, we use enteric-coated capsules. These should not be opened, as doing so may alter the intended release profile.

These include, for example:

  • Bacterial preparations, such as HistaBakt, MakroAktiv, and BactoGena 21+2
  • Enzyme products, such as N-Zymarase® Intest and N-Zymarase® Inflam. Exception: N-Zymarase Komplex contains betaine HCl, which is intended to take effect in the stomach; therefore, it does not have an enteric-coated capsule shell and can be opened
  • Soft capsules with liquid contents, such as omega-3 capsules, are also not intended to be opened. In this case, you can switch to the liquid oil instead.

If you have any questions, please contact our advisory team at info@natugena.de.

From the very beginning, NatuGena has used exceptionally pure, plant-based HPMC capsules in the majority of its products. HPMC stands for hydroxypropyl methylcellulose and is made from plant-based cellulose.

Unlike many HPMC capsules commonly available on the market, the coating agents we use contain no carrageenan or PEG. Although they are more expensive, they meet our high standards for a carefully selected and transparent product composition.

Our plant-based HPMC capsules are:
  • 100% plant-based cellulose (HPMC)
  • Carrageenan-free
  • PEG-free
  • Gelatin-free
  • GMO-free
  • Free of allergens and irritants
What types of capsule shells are used in omega-3 products?

Special softgels are required for liquid oils. Our classic omega-3 capsules therefore contain a coating made from gelatin and glycerin and are not vegan.

In our vegan omega-3 capsules made from algae oil, the coating consists of glycerin and modified cornstarch and contains no gelatin. This makes these capsules suitable for a vegan diet.

The exact composition of each coating agent is clearly listed in the ingredients list.

It All Comes Down to the Composition

Conventional capsule shells may contain technical additives—such as anti-caking agents, release agents, or binders—due to the manufacturing process. These components aren’t always immediately apparent, as certain processing aids aren’t required to be listed in the ingredients list.

People who take several dietary supplements daily, in particular, regularly ingest not only the actual ingredients but also the respective capsule shells. That is why at NatuGena, we pay close attention not only to the quality of the nutrients and plant-based ingredients contained in our products but also to the composition and processing of the capsule shells. For us, transparency, purity, and quality go hand in hand.

Most of the NatuGena capsule products are size 00 (8,2 × 23,3 mm) to 0 (7,3 × 21,2 mm). Information on the capsule sizes of individual products can be found on the relevant product page or by contacting info@natugena.de

We work with the independent laboratory AgroLab, which we commission to perform microbiological and heavy metal tests.

In our microbiological testing, we measure the aerobic mesophilic plate count (total plate count), as well as the levels of Escherichia coli (E. coli), yeasts, Salmonella, molds, and staphylococci.

For heavy metals, we test for arsenic, lead, cadmium, and mercury in accordance with the limit values specified in Regulation (EU) 2023/915.

The optimal duration of use depends on the specific nutrient, your initial situation, diet, and individual requirements.

There is therefore no one-size-fits-all recommendation for how long a product should be taken. For products intended to support nutrient intake over a longer period, use over several weeks to months may be appropriate. In many cases, a period of around three months may be suitable before nutrient status and further requirements are reassessed.

In the case of diagnosed deficiencies, medical conditions, or the use of medication, the use of supplements should be individually discussed with a doctor or qualified healthcare professional.

The optimal time to take a supplement depends on the specific nutrient, individual tolerance, and the composition of the product. However, some ingredients can be particularly well suited to certain times of day or meals.

In the morning

Stimulating ingredients are often preferably taken in the morning or during the first half of the day. These include, for example:

  • Coenzyme Q10
  • Green tea extract
  • Certain B vitamins

Especially for sensitive individuals, it may be advisable to avoid taking stimulating ingredients immediately before bedtime.

Throughout the day

For some nutrients, it may be beneficial to divide the daily amount into several doses.

Water-soluble vitamins such as B vitamins and vitamin C can be taken throughout the day.

Magnesium can also be divided into several doses rather than taking the entire daily amount at once. This may improve tolerance, particularly with higher amounts.

In the evening

Depending on the type of magnesium compound, taking it in the evening may be beneficial. Magnesium glycinate, for example, is often preferably taken in the evening.

In general, however, the best time to take a product also depends on when it is individually best tolerated and can be reliably incorporated into your daily routine.

With a meal

Some nutrients benefit from being taken together with a meal.

Fat-soluble vitamins A, D, E, and K can be taken together and ideally with a meal containing some fat.

Omega-3 fatty acids should also be taken regularly with a meal. Omega-3 oils can be combined well with fat-soluble vitamins.

Many plant-based ingredients can also be taken as part of a meal or together with omega-3 products. However, the optimal timing depends on the specific plant compound and product formulation.

Zinc can cause nausea or stomach discomfort on an empty stomach in some people. If you have a sensitive stomach, it is therefore advisable to take zinc with a meal.

Between meals

Iron is often taken separately from meals, as various foods and beverages can affect its absorption. It is particularly advisable to leave a gap between iron and:

  • Coffee and tea
  • Caffeinated beverages
  • Milk and dairy products
  • Calcium- or mineral-rich supplements

However, if you have a sensitive stomach, iron can also be taken with a meal. In this case, individual tolerance is more important than a theoretically optimal intake situation.

Enzyme supplements vary depending on their intended use: digestive enzymes are generally taken with meals. Products that are specifically intended to be taken between meals may, for example, be taken around 30 minutes before a meal. The product's specific recommended intake should always be followed.

Around exercise

Proteins and amino acids can be taken both before and after training.

If you exercise on an empty stomach, taking them around 30 minutes before training may be beneficial. If you have already eaten a protein-rich meal, you can also plan your protein intake for after training.

In general, ensuring sufficient protein intake throughout the entire day is more important than adhering to a narrow time window around your workout.
