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.
Absolute Purity: No Hidden Additives
Our branded active ingredient Sunferol® D3 Vegan is a special formulation with high-quality vitamin D3 from a completely plant-based source. For optimal intake and maximum stability, we suspend our premium D3 in MCT coconut oil.
Conventional vitamin D3 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 vitamin D3 is specially manufactured according to our specifications, thereby avoiding such hidden additives. The purity of this raw material means only a small amount of the natural, bioactive form of vitamin E (D-alpha-tocopherol from sunflowers) 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 and solvent residues.
MCT Coconut Oil for Optimal Absorption & Protection
Vitamin D is a fat-soluble vitamin that can only be absorbed by the body when combined with fats. For this reason, Sunday Natural's vitamin D3 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 D
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 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 immune system function
Vitamin D has a role in the process of cell division.
Dosage
Dosage
Directions
Take 1 drop daily with a meal on a spoon or in a drink. Shake well before use.
Daily Requirements
The contradictory information surrounding daily requirements for vitamin D intake can be 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.
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.
