How are we different?
Absolute Purity: Guaranteed No Additives
Our branded active ingredient Sunferol® D3 is a special formulation with high-quality vitamin D3 obtained from the wool wax of sheep. 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.
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
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 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 synthetic 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.
Effects
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. 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 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
Dosage
Directions
Take 1 drop with a meal every 10 days.
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 healthy lifestyle. Keep out of reach of young children. Note: Not suitable for children under 7 years.
Storage
Store in a cool, dry place away from direct sunlight and heat. To optimise shelf-life, keep in the refrigerator.
