How are we different?

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 highly 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 ingredients from oxidation, allowing for a prolonged 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 from sustainable cultivation. In contrast to the usual synthetic fillers, we use an ultra pure natural filler that is also rich in dietary fibre. The soluble dietary fibres of acacia are extremely well tolerated by the body and function as a source of bifido and lacto bacteria in the intestine. 

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.


  • Premium active ingredients in their purest form
  • Sourced directly from the world’s best producers
  • Our select raw materials are the basis of all our formulations
  • Complete avoidance of all unnecessary additives and adjuvants
  • Exclusive use of valuable natural ingredients for additives

  • All extractions performed without the use of chemical solvents
  • Custom production when necessary, in order to achieve the highest possible level of purity
  • Independent laboratory testing available on product pages
  • Raw materials sourced only from premium suppliers who are committed to fair working conditions

  • Vegan capsule shells, free from PEG and carrageenans
  • Packaged in the EU according to HACCP, GMP and ISO 22000:2018 standards
  • Stored in non-toxic containers
  • Shipped in mineral oil-free boxes

Vitamin D and Vitamin K2

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.

A pre-existing vitamin K2 deficiency combined with vitamin D3 supplementation can increase the risk of calcium buildup in blood vessels and organs (leading to calcification, arteriosclerosis, kidney stones, etc.). Sunday Natural Vitamin D3 and K2 MK7 combines the two nutrients in a ratio that ensures optimal synergy.

Health Benefits of Vitamin D (According to the EFSA)

Vitamin D contributes to:

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

and vitamin D has a role in the process of cell division.

Vitamin D is still being researched and new properties of this vitamin are still being discovered on an almost yearly basis.

Sunday Natural Premium Vitamin D3

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 D is a fat-soluble vitamin that can only be absorbed by the body when combined with fats. Our vitamin D3 is therefore dissolved in MCT coconut oil and then dried to make a fine powder. The powder also contains fat-soluble vitamin E in the form of natural D-alpha-tocopherol. As a result, it exists in a form that can be readily absorbed by the body. The high-quality, medium-chain fatty acids of the MCT oil and vitamin E offer valuable nutrients themselves.

In order to achieve an even distribution of vitamin D3 in the active ingredient powder and thus a precise dosage, we use only highly pure, 100% nanoparticle-free microcrystalline cellulose. This allows us to avoid variation in active ingredient content between capsules, which is common among many other brands.

Health Benefits of Vitamin K (According to the EFSA)

Vitamin K contributes to:

  • Normal blood clotting
  • The maintenance of normal bones

Most organisations do not consider vitamin K1 and K2 separately and, as such, there is not extensive information available on the benefits of vitamin K2 specifically. As such, our statements about vitamin K2 are based on the assumption that K1 and K2 function similarly.

Vitamin K2 MK7: All-Trans from Norway

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.

Original K2VITAL® vitamin K2 from Norway is one of the few commercial supplements that consists of 100% highly effective all-trans MK7, guaranteed by Norwegian laboratory testing.

Practical Capsules

Our ultra pure, PEG- and carrageenan-free capsules dissolve quickly in the stomach to release the active ingredient. In contrast to tablets, the loose powder in the capsules has not been pressed and can therefore be better absorbed by the body.

Furthermore, we ensure that each of our high-dose capsules contains an exact dose of active ingredients. With capsules, we can achieve precision and avoid common fluctuations in dosage. Thus our capsules contain the exact dosage listed, eliminating the potential for accidental over- or under-dose.

Premium Acacia Fibre

Acacia fibre is a well tolerated, water-soluble natural fibre. It serves as a food source for bifido and lacto bacteria. The bacteria process the acacia fibre into short-chain fatty acids, which nourish the intestinal mucosa. Our premium sustainable acacia fibre powder is an organic, GMO-free natural substance of the highest quality, derived from the acacia gum of specially selected Acacia senegal trees in Africa.

Our producer works with and supports local communities in the Sahel region (also known as the Gum Arabic Belt). The brand prioritises sustainability, and does not use pesticides.


Recommended Dosage

Take 1 capsule (5,000 IU vitamin D3 + 200µg K2 MK7) every 5 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.

Daily Cofactor Requirements

The German Nutrition Society recommends a daily intake of between 300 and 400mg of magnesium (NRV: 375mg). However, individual magnesium needs may vary according to biochemical factors, and can be significantly increased during stressful periods.

Note: According to the German Federal Institute for Risk Assessment (BfR), magnesium intake through supplements should not exceed a maximum daily amount of 250 mg of magnesium in food supplements in order to avoid a laxative effect (mild diarrhoea). The maximum amount applies to persons aged four years and older. For infants under four years of age, there is no such guidance relating to a daily maximum due to lack of data.

The BfR recommends that the daily dose be divided into at least two separate doses per day. This is because scientific data shows that magnesium tolerability is increased when intake is spread between two or more portions per day.

The official daily requirement for calcium according to the German Nutrition Society (DGE) is 1,000mg (NRV: 800µg). Adolescents between the ages of 13 and 19 have an increased calcium requirement of 1,200mg per day, while the elderly and those suffering from certain diseases may be at a higher risk of developing a calcium deficiency.

Vitamin A
The German Nutrition Society recommends a daily intake of 1mg retinol (vitamin A) for men over the age of 19, and 0.8mg for women, while breastfeeding women have an increased vitamin A requirement of 1.5mg per day, and pregnant women and boys between the ages of 13 and 15 of 1.1mg per day.


Vitamin K2
If you are taking blood thinners (e.g. coumarin, warfarin, or Marcoumar), or suffering from a blood coagulation disorder, consult a doctor before taking this product. Vitamin K2 promotes blood coagulation and can interfere with blood thinners.

If you have a thyroid or iron metabolism disorder, medically treated cardiac arrhythmia, or are suffering from kidney failure, consult a doctor before taking magnesium.

Calcium is contraindicated in cases of hypersensitivity, calcemia, calcium oxalate stones, nephrocalcinosis, hypercalciuria, and kidney failure.

Food Supplement

Do not exceed the recommended dose. Nutritional supplements cannot replace a balanced and varied diet. Keep out of reach of children.
