How are we different?

Vegan Vitamin D3

Vitamin D3 is found almost exclusively in animal products, meaning that the vitamin D3 found in supplements is usually obtained from raw materials such as sheep's wool, fish oil and shellfish. However, years of research have recently led to the discovery of a purely plant-based source of vitamin D3, meaning we can now offer entirely natural and vegan vitamin D3 products.

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.

Sunday Natural vitamin D drops contain only 2 ingredients: vitamin D3 and MCT oil.

MCT Coconut Oil for Optimal Absorption

Vitamins D is a fat-soluble vitamin that can only be absorbed by the body when combined with fats. Sunday Natural vitamin D3 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, vitamin D3 combined with oil is 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 precision dropper.

Vitamin D

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 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.


Recommended Dosage

Take 1 drop with food every 10 days.

Daily Requirements

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.

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.
