How are we different?

Most vitamin D tablets on the market contain a large amount of unnecessary and controversial additives. Such additives may already be a component of the active ingredient, used as fillers, pressing and anticaking agents such as magnesium stearate, or are added for flavour or colour. By contrast, our custom-made active ingredients as well as our unique production process ensure that our vitamin D tablets are completely free from any controversial or synthetic ingredients. For optimal absorption, we further use a natural MCT coconut oil in which the fat-soluble vitamin D3 can be mixed and made even more bioavailable to the body. We can confidently say that Sunday Natural offer the purest and most effective vitamin D tablets on the market.

Additives that are already contained in the active ingredient are not legally required to be on the product label. As a result, most vitamin D tablets contain "hidden" synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starches, sucrose, denatured plant oils, and maltodextrin. Because none of the sources of vitamin D on the market that we could find were able to match our demands for purity, we use an exclusive vitamin D active ingredient that is custom made according to our strict specifications. Our vitamin D is completely free from common "hidden" additives.

To ensure that there is an absolutely even amount of vitamin D3 mixed throughout the supplement powder and thus to ensure an exact dosage of the tablets, a carrier material is needed. We exclusively use ultra pure and 100% nanoparticle-free microcrystalline cellulose while many generic tablets use microcrystalline powders with up to 10% undeclared nanoparticles.

As a fat-soluble vitamin, D3 can only be absorbed with oil. Our tablets therefore contain high-grade MCT coconut oil in powder form for optimal absorption. Natural vitamin E is added to protect the D3 from oxidation and lengthen the product's shelf life.

Our vitamin K2 comes from a top European manufacturer and is a premium active ingredient. It is one of the few commercial supplements on the market that consists of 100% highly effective all-trans MK7, guaranteed by Norwegian laboratory testing. Impurities and fluctuations in quality among batches are therefore not an issue.

The only other ingredient we use is premium acacia fibre cultivated without pesticides. In contrast to the usual synthetic fillers, we use an ultra pure natural filler that is also rich in dietary fibre. Our acacia fibre is sourced from climate neutral, resource-saving, sustainable and fair cultivation.

Vitamins D and K2

Vitamin D3 occurs in nature almost exclusively in animal sources and particularly in fish, dairy products, eggs and meat. Plants, such as lichens and various fungi contain only very small amounts of the much less effective vitamin D2.

Vitamin D plays a very important role. It is one of the few vitamins that is not absorbed directly from food, but rather produced by skin cells from sunlight. It is not a vitamin in the traditional sense of the word, but rather a pro-hormone.

In contrast to many other vitamins, vitamin D is converted into an important hormone which regulates cell functioning and bodily processes. Almost all bodily cells have special receptors for the vitamin D hormone that are dependent on sufficient supply.

Vitamin D and vitamin K2 are cofactors in the regulation of calcium metabolism.Together, the two vitamins control the formation and breakdown of bone cells and important transport molecules that ensure the correct utilisation of calcium. Sunday Natural Vitamin D3 and K2 MK7 combines the two nutrients in a ratio that ensures optimal synergy.

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 (EFSA):

Vitamin D contributes to

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

Vitamin D has a function in cell division.

Vitamin K contributes to

  • Normal blood clotting
  • The maintenance of normal bones

Vitamin K2 exists in different forms, each of which has a different level of efficacy. Vitamin K2 MK7 is today considered by far the most effective form of K2. Since vitamin molecules take different chemical forms (the so-called cis-trans isomers of vitamin K2), there are enormous differences even between different vitamin K2 MK7 active substances. It is believed that only the trans forms can be utilised by the body.


Recommended Dosage

Take 1 tablet every 20 days with 200ml water at mealtimes.

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

Daily Requirements

Vitamin D3

The contradictory information surrounding 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.

However, numerous researchers and nonprofit organisations believe that these recommendations are too low and are not enough to prevent deficiency. An intake of at least 1,500-2,000 IU or 3,000-6,000 IU are recommended by the American Endocrine Society and the Vitamin D Council (USA), respectively.

Vitamin K2

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

Note: Recent research shows that vitamin K1 and vitamin K2 have distinctly different profiles in terms of their effects. Vitamin K2 requirements have not yet been scientifically established, but are likely higher than those listed by the DGE. A complete carboxylation of Matrix GLA protein (MGP) and osteocalcin, which is the main function of vitamin K2, can be observed in doses starting from 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. Not suitable for children under the age of 7.


Store in a cool, dry, dark place.
