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 (cholecalciferol). A multi-stage process, which includes gentle extraction and intensive purification, results in a highly pure crysallised D3 that is used as the active ingredient for our vegetarian Sunferol® D3 formulation.
All-trans Vitamin K2
Vitamin K2 exists in various molecular forms, which are referred to as MK-4 and MK-7 depending on the length of their side chains. MK-7 is considered the most effective form of vitamin K2, as it remains active in the body for an exceptionally long time and meets the functional K2 requirement even at low dosages. However, there are further variants within the MK-7 form. Only the trans form has full biological effectiveness. An active ingredient declared as "all-trans" must therefore consist of at least 98% vitamin K2 MK-7 in this effective trans form.
Special caution is required in the area of vitamin K2. Despite manufacturers' claims, widespread label fraud occurs here. Independent laboratory tests show that many supplements declared as "all-trans K2" often 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 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. 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 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 uses high-quality MCT oil as a carrier 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 synthetic plant protection products.
No Hidden Additives
The only other ingredient we use in our vitamin D tablets is gum arabic – a pure, natural filler for tableting. Unlike the synthetic fillers usually found in such products, we use a natural substance that is also a natural foodstuff.
Effects
Vitamin D & Vitamin K2
Vitamin D and vitamin K2 are cofactors in the regulation of calcium metabolism. Together, the two vitamins form and break down bones as well as the important transport molecules which ensure the correct utilisation of calcium. This product's ratio of vitamin D3 to K2 MK-7 is specially formulated to ensure their optimal interaction.
Vitamin D is still the subject of intensive research. New mechanisms of action of this fascinating vitamin are discovered almost every year. To date, the following statements on vitamin D have been approved 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
Currently, almost all authorities do not consider vitamin K2 separately, but all K vitamins together. Accordingly, the statements released for vitamin K1 currently apply to vitamin K2.
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 tablet every 20 days with 200ml water with a meal.
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 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 1500–2000 IU or 3000–6000 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 per day.
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.
Storage
Store in a cool, dry place away from direct sunlight and heat.
