Premium Bioactive Ingredients
How are we different?
Natural Vitamin D3
Vitamin D3 naturally occurs almost exclusively in animal sources as the bioactive form of vitamin D. Plants, such as lichens and various fungi, contain only very small amounts of the much less effective form of vitamin D2. Lanolin, the wax found in sheep's wool, is a proven source for obtaining bioactive vitamin D3. A multi-stage process, which includes gentle extraction and intensive purification, results in a highly pure D3 crystallisate that is used as the active ingredient for our vegetarian Sunferol® D3 formulation.
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, vitamin K2 molecules occur in a variety chemical structures; 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 premium branded active ingredient, delivering an exceptionally high MK7 all-trans content of approximately 99.8%. This consistently high degree of purity is rigorously verified through comprehensive independent laboratory testing.
Absolute Purity: No Hidden Additives
Our branded active ingredients Sunferol® D3 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
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 Dosing
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 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. Our 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 immune system functioning
- 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
Directions
Take 1 drop daily with a meal.
Daily Requirements
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 dose. Food supplements cannot replace a balanced, varied diet and 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.
