How are we different?

All of our vegetarian vitamin D products contain premium vitamin D3 as an active ingredient, which is custom-made according to our strict specifications, and without any additives except vitamin E and a high quality MCT coconut oil as a carrier oil. This product is notable for its absolute purity and guaranteed vitamin D3 content. Vitamin D3 products often contain a wide variety of different additives, including some which are highly questionable but are not legally required to be declared, such as synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils, and maltodextrin. However, our vitamin D3 is ultra pure due to our unique production process. It is custom-made for us by a specialised manufacturer according to our strict specifications and is completely free from common hidden additives.

In order to achieve an even distribution of vitamins D3 and K2 in the active ingredient powder and thus a precise dosage, only highly pure, 100% nanoparticle-free microcrystalline cellulose is used. Our vitamin D3 powder is also rich in high-quality MCT (coconut) oil for optimal absorption of fat-soluble vitamin D3. Natural vitamin E protects the active ingredient from oxidation, allowing for a prolonged shelf life.

We also use premium bioactive K2 MK7 all-trans by Norwegian brand Kappa, a leading producer in Europe. It is one of the few commercial supplements on the market that consists of 100% highly effective all-trans MK7. Impurities and fluctuations in quality among batches are therefore not an issue.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC capsules that can be found on the market, are 100% free from controversial additives such as carrageenans and PEG. We use environmentally friendly amber glass jars for the packaging of this product.

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 capsule with food every 20 days.

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.
