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.
Absolute Purity: No Hidden 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. 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
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.
