Premium Bioactive Ingredients
How are we different?
Natural Vitamin D3
All of our vitamin D3 oils contain a high-quality premium vitamin D3 as the active ingredient, which has been specially produced for us without any hidden additives—only with MCT oil from coconut and natural vitamin E. The active ingredient is characterised by its purity and guaranteed vitamin D3 content. D3 active ingredients very often contain a whole range of additives, some of which do not have to be declared, such as synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils and maltodextrin. Our vitamin D3 is particularly pure and free from the usual hidden additives due to the elaborate special production according to our specifications.
All-trans Vitamin K2
Vitamin K2 exists in various molecular forms, which are referred to as MK-4 and MK-7 depending on the length of their side chains. MK-7 is considered the most effective form of vitamin K2, as it remains active in the body for an exceptionally long time and meets the functional K2 requirement even at low dosages. However, there are further variants within the MK-7 form. Only the trans form has full biological effectiveness. An active ingredient declared as "all-trans" must therefore consist of at least 98% vitamin K2 MK-7 in this effective trans form.
Our original K2VITAL® vitamin K2 from Norway is one of the few commercial supplements that consists of at least 99.7% highly effective all-trans MK-7, guaranteed by Norwegian laboratory testing.
MCT Coconut Oil for Optimal Absorption & Protection
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.
Simple & Precise Dosage
Oils are easy to use and are therefore suitable for those who have difficulty swallowing capsules and tablets. They also offer the advantage of direct absorption through the oral mucosa, meaning the fat-soluble vitamins are immediately bioactive. All our oils come in environmentally friendly amber glass bottles with a glass dropper for precise usage.

Effects
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 in the body. 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 MK-7 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 calcium levels in the blood
- The maintenance of bones
- The maintenance of normal muscle function
- The maintenance of healthy teeth
- Normal function of the immune system
- Cell division
Vitamin K contributes to:
- Normal blood clotting
- The maintenance of normal bones
Vitamin K2 exists in various forms, which have different levels of effectiveness. Vitamin K2 MK-7 is considered by far the most effective form of K2 today. However, since vitamin K2 molecules occur in a variety chemical structures (the so-called cis–trans isomers of vitamin K2), there are considerable differences in efficacy even between different vitamin K2 MK-7 compounds. It is believed that only the trans forms can be utilised by the body.
Dosage

Daily Requirements
Vitamin D
The National Health Service (NHS) recommends a daily intake of 10μg of vitamin D for those 1 year of age and older, inclusive of those pregnant, breastfeeding and at risk of vitamin D deficiency. The NHS recommends a daily intake of 8.5-10μg of vitamin D for babies up to the age of 1 year. However, it is important to note that individual vitamin D needs may vary according to geographic location (sun exposure), dietary habits, genetics and other factors.

The National Health Service (NHS) does not currently have any published recommendations regarding daily intake of vitamin K.

Product Details
Our in-house production guarantees uncompromising purity and quality. Production, bottling and encapsulation take place in the EU according to our own rigorous specifications and in strict compliance with HACCP, GMP and ISO 22000:2018 standards.
Bespoke liquid formulations, (functional) foods for athletic and daily performance and select exclusive items are produced as high-grade custom preparations by chosen partners who share our commitment to quality, adhering strictly to HACCP, GMP and ISO standards.
In line with our True Clean Label philosophy, we refrain from using artificial additives, colourants and preservatives intended to standardise product appearance. Consequently, formulations containing natural botanical extracts and plant-based raw materials may display subtle batch-to-batch colour variations. These variations stem from natural factors such as harvest timing (seasonal differences between early and late harvests), origin (geographical soil and climate fluctuations) or processing dynamics (variations in particle grind size). Such natural shade shifts may also occur in our plant-based or compressed tablets formulated with premium acacia fibre or nanoparticle-free cellulose and do not constitute a defect in quality.
Laboratory Tests
The purity of our formulas is important to us. This is why we have both our raw ingredients as well as our finished products extensively tested by independent laboratories to confirm purity and active ingredient content. Here, we have provided the results of some of the tests carried out on this product.
