Premium Bioactive Ingredients
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. Plants, on the other hand, contain only very small amounts of the much less effective form of vitamin D2. However, years of research have recently led to the discovery of a completely plant-based source of vitamin D3: a multi-stage process, which includes the conversion of plant precursors into bioactive vitamin D3 and intensive purification, results in a D3 crystallisate with a purity of over 99%. This means we can now offer entirely natural and vegan vitamin D3 products with Sunferol® D3 Vegan.
All-Trans Vitamin K2
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, as it remains active in the body for a particularly long time and is able to cover the functional K2 requirement of the body in relatively small doses. 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.
Vitamin K2 is designated "all-trans" when it consists of at least 98% trans isomers. Despite manufacturers' claims, widespread label fraud occurs in the sale of vitamin K2. Independent laboratory tests prove that many supplements declared as all-trans K2 often actually contain only small amounts of all-trans vitamin K2.
Our original Sunquinone® K2 is a branded active ingredient with a uniquely high MK-7 all-trans content of approximately 99.8% in the raw material. The consistently high purity is ensured by independent laboratory tests.
Absolute Purity: No Hidden Additives
Our branded active ingredients Sunferol® D3 Vegan and Sunquinone® K2 are specially manufactured for Sunday Natural – made from natural raw materials and with particular emphasis on purity and quality.
Conventional vitamin D3 + K2 active ingredients are often mixed with a whole range of questionable additives, including synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils and maltodextrin. However, our active ingredients are specially manufactured according to our specifications, thereby avoiding such hidden additives. The purity of these raw materials means only a small amount of bioactive vitamin E needs to be added as an antioxidant to ensure optimal stability and shelf life.
To maintain the excellent quality of our products, they are regularly tested in an independent laboratory for active ingredient content, freshness and possible contaminants such as heavy metals.
MCT Coconut Oil for Optimal Absorption & Protection
Vitamins D and K2 are fat-soluble vitamins that can only be absorbed by the body when combined with fats. For this reason, Sunday Natural's vitamin D3 + K2 is dissolved in high-quality MCT oil. In contrast to other carrier oils (such as olive oil), pure MCT oil offers optimal protection for fat-soluble vitamins, thus ensuring maximum stability of the active ingredients. The medium-chain fatty acids in the carrier oil constitute valuable nutrients themselves. Our oil, which is processed in the Netherlands, is grown without the use of plant protection products.
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, making them immediately bioactive. All our oils come in environmentally friendly amber glass bottles with a glass dropper for precise usage.

Vitamin D3 & K2
Vitamin D3 naturally occurs almost exclusively in animal sources, 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 form of 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. Almost all body cells have special receptors for the vitamin D hormone and are dependent on an adequate supply of it.
Vitamin K2 is the most important cofactor of vitamin D in the regulation of calcium metabolism. Together, the two vitamins control bone-building as well as breaking down cells and important transport molecules that ensure the correct utilisation of calcium.
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:
- the 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
- the 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
Dosage
Directions
Take 4 drops with a meal every 20 days. Shake well before use.
Food Supplement
Vitamin D
The different information on the exact dosage of vitamin D can be confusing. Recommendations vary greatly from organisation to organisation.
For adults, for example, the EU recommends 200 IU, while the German Nutrition Society (DGE) recommends 800 IU. However, many researchers and non-profit organisations consider these recommendations to be too low to prevent a deficiency or maintain vitamin D levels.
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.
Food Supplement
Do not exceed the recommended daily intake. Food supplements are not a substitute for a balanced, varied diet and a healthy lifestyle. Keep out of reach of young children.
Storage
Store in a cool, dry place away from direct sunlight and heat. To optimise shelf-life, keep in the refrigerator.
