In NatuGena Selenium 100 Liquid, we use selenium in the form of sodium selenite, an inorganic, water-soluble compound that is immediately bioavailable. This form does not require enzymatic conversion and is therefore particularly suitable for direct, efficient nutrient support.

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.

We offer a range of different products for children:
- Gummies
- Juice
- Capsules
- Drops
All-Rounders
For children and teenagers, we recommend the delicious Wowtamins gummies. They contain vitamins as well as zinc, iodine, selenium, and omega-3.
- wowtamins KIDS Complete for ages 4–9 – also available sugar-free
- wowtamins TEENS sugar-free for ages 10–17
If omega-3 is taken separately as a liquid oil, wowtamins KIDS Multi Gummies can be used without omega-3 for children aged 4–9.
Nutrient support is particularly easy for children with our all-rounder MultiVegan – one capsule already contains 200 mg calcium, 3 mg iron, 50 µg iodine, 20 µg selenium, 2 mg zinc, and vitamins B2, B9, and B12.
Immune System
Curcuma Liquid is a delicious juice containing a phyto-complex with vitamin C and 95% curcuminoids. Our Immune Set provides all important vitamins and trace elements for the immune system as a value set.
Colostrum contains important immunoglobulins (IgA, IgG, and IgM). It is obtained from the first milk of mammals. Colostrum is also well suited for children.
Gut and Digestion
MukosaRepair Powder contains, among other ingredients, L-glutamine, aloe vera, and licorice root (DGL). The formula with plant extracts is traditionally used to support mucous membranes (e.g. in the gut) and has a pleasantly sweet taste thanks to stevia – making it suitable for children as well.
BactoGena Liquid Plus is a liquid herbal ferment containing bioactive enzymes, 33 selected microorganisms, and 20 organically grown herbs. It is suitable for adults, children from the age when complementary foods are introduced, and pregnant women. Not suitable for people with histamine intolerance. Alternatively, BactoGena Liquid Pur is also available without the herbal taste.
Minerals
If there is an increased need for minerals, the gummies can be supplemented with Magnesium Malate & Glycinate. This product has the smallest capsule size of our magnesium products.
For an increased need for iron, we offer wowtamins Iron Gummies. Alternatively, you can choose our Vegan Iron or Liposomal Iron.
OrgaMin Powder provides a comprehensive spectrum of 14 different minerals. The measuring spoon allows for flexible dosing, and the powder can be mixed with water.
Vitamins & Omega
Omega Kids Vegan was specifically developed for children aged 4 and over. It provides 284 mg of omega-3 fatty acids per daily serving (2.5 ml) and also contains 400 IU of vitamin D.
Vitamin D may be beneficial for children. We offer different dosage forms (drops, tablets, and capsules) – see our vitamin D products.
Our vitamin B complex, HydroVitamins, offers flexibility with 3 small capsules, which can also be opened. For vitamin B12, we offer a liquid product with a convenient 10 µg per drop for flexible dosing.
Dosage
In general, the recommended intake stated on the packaging applies to adults. Since children’s nutrient requirements vary depending on age, body weight, diet, and individual circumstances, the use and dosage of our products should be discussed with the treating pediatrician in advance. Please note that not all ingredients and products are suitable for children. Suitability should therefore always be professionally assessed on an individual basis.
Many capsules can generally be opened and their contents mixed into food or a drink, such as (coconut) yogurt, applesauce, or mashed potatoes. However, this should not be used as a basis for independently determining the dosage for children.
For drops as well, the amount and frequency of intake for children should be determined individually based on tolerance and need, in consultation with a healthcare professional.
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.
