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.

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.

MCT Coconut Oil for Optimal Absorption

Vitamins D and K2 are both fat-soluble vitamins that can only be absorbed by the body when combined with fats. Sunday Natural Vitamin D3 + K2 is dissolved in high-quality MCT oil for optimal bioavailability and can therefore be directly utilised by the body. In contrast to capsules and tablets that must first be digested in order for their active ingredients to be released, vitamins D3 and K2 combined with oil are readily available and can be optimally absorbed. Our MCT coconut oil is completely free from additives and the medium-chain fatty acids in the carrier oil constitute valuable nutrients themselves.

Oils are easy to use, and are therefore suitable for those who have difficulty swallowing capsules and tablets. All our oils come in amber glass bottles with a high-quality glass dropper. In contrast to dispensing bottles, which are often difficult to use and clog easily, glass droppers are ideal for precise usage.

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 drop with food every 5 days.

Daily Requirements

Vitamin D

Determing the correct dosage of vitamin D can be very confusing because recommendations vary greatly from organisation to organisation.

For adults, for example, the EU recommends 200 IU but the German Nutrition Society (DGE) recommends 800 IU.
However, many researchers and non-profit organisations consider these recommendations too low to prevent a deficiency or even to maintain vitamin D levels.

Vitamin K2

There is currently no single recommendation for vitamin K2. The German Nutrition Society recommends a total vitamin K intake of at least 70µg.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Note: Not suitable for children under 7 years. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat. To optimise shelf-life, keep in the refrigerator.
