How are we different?

Most vitamin D capsules on the market today contain unnecessary additives such as fillers, pressing and flow agents, excipients, flavourings and colourings. In contrast, the active ingredient contained in this formulation was custom made for us without any synthetic ingredients, including magnesium stearate. In addition, suspending the fat-soluble vitamin D in MCT oil derived from coconut allows for optimal absorption and bioavailability, making our vitamin D capsules some of the most pure and effective available.

By law, additives contained in the active ingredient do not have to be disclosed. This allows manufacturers to hide additives such as synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils and maltodextrin. Finding no vitamin D active ingredients which met our purity standards, we created our own according to our exact specifications: completely free from hidden additives.

In order to achieve an absolutely even distribution of vitamin D3, and thus ensure precisely dosed capsules, the addition of a carrier is necessary: our formulation includes 100% non-nano microcrystalline cellulose as a carrier; commercially available microcrystalline cellulose may contain up to 10% nanoparticles without this having to be declared.

As a fat-soluble vitamin, vitamin D can only be absorbed by the body in the presence of fats. To ensure optimal absorption, our capsules contain high-quality powdered MCT oil derived from coconut. The addition of natural vitamin E protects the active ingredient from oxidation, ensuring a particularly long shelf life.

Our vitamin K2 comes from the leading European producer of vitamin K2. In contrast to cheaper alternatives, our active ingredient contains a total of 100% K2 MK-7: the only biologically active MK-7 isomer. Inconsistent quality, as well as the presence of impurities and high proportions of ineffective forms of K2, is not an issue here.

The only other ingredient is premium acacia fibre, cultivated without the use of plant protection products. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural, fibre-rich food. Our fair trade acacia gum is climate neutral and is sustainably cultivated to conserve resources.

Vitamin D and Vitamin K2

Vitamin D and vitamin K2 both play key roles in calcium metabolism. Together, they regulate the cells which form and break down bones as well as the important transport molecules which ensure the correct utilisation of calcium. This product's ratio of vitamin D3 to K2 MK-7 is specially formulated to ensure optimal interactivity between these two nutrients.

Vitamin D is still being intensively researched. New mechanisms of action of this fascinating vitamin are discovered almost every year. So far, the following statements on vitamin D have been released by the EU via the European Food Safety Authority (EFSA):

According to EFSA, vitamin D contributes to:

  • Normal absorption and utilisation of calcium and phosphorus
  • Normal calcium levels in the blood
  • The maintenance of bones
  • The maintenance of normal muscle function
  • The maintenance of healthy teeth
  • Normal immune system functioning
  • Cell division

As far as their effects on the body, virtually every health authority currently treats the vitamins of the K group as one. Accordingly, statements released for vitamin K1 are also attributed to vitamin K2.

According to EFSA, vitamin K contributes to:

  • Normal blood clotting
  • The maintenance of normal bones

Vitamin K2 occurs in a variety of molecular structures known as homologues. Although the MK-7 homologue is currently considered the most effective, only the trans isomers are bioactive.


Recommended Dosage

Take 1 capsule with food and 200ml water every 10 days.

Note: Not suitable for children under the age of 7.

Daily Requirements

Vitamin D3
The contradictory information regarding daily requirements for vitamin D intake can be very confusing. Daily recommendations vary greatly between different organisations and governing bodies. For example, the EU recommends a daily intake of 200 IU for adults, while the German Nutrition Society (DGE) recommends 800 IU.

Many researchers and nonprofit organisations consider these recommendations too low to effectively prevent deficiency. The Endocrine Society, for example, recommends 1,500–2,000 IU per day, and the Vitamin D Council (USA) sets the requirement at 3,000–6,000 IU/day.

Vitamin K2
Although the DGE recommends a total intake of at least 70µg vitamin K per day, there are currently no recommendations for vitamin K2 specifically.

Note: Recent research has shown that vitamin K1 and K2 have significantly different effect profiles. Given this new evidence, care must be taken when treating these forms as one. Though the need for vitamin K2 has not yet been scientifically proven, complete carboxylation of matrix GLA protein and osteocalcin – the central task of vitamin K2 – can only be achieved from doses of about 100µg/day.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.
