How are we different?
Natural Vitamin D3
Our Sunferol® D3 Vegan is sourced from pine trees. The pine oil is sustainably obtained as a byproduct of forestry (bark, branches), meaning that pine trees do not need to be cultivated or felled specifically for vitamin D production, as the raw material originates from an existing circular system. This provides a key advantage over vegan vitamin D sourced from algae or lichen, which are grown exclusively for vitamin D production. Unlike resource-intensive algae cultivation, production from pine oil requires neither controlled bioreactors nor artificial lighting or heating systems. Our vegan vitamin D from pine oil can therefore be produced more cost-effectively and with significantly lower energy and raw material consumption.
Through a multi-stage process involving the conversion of plant precursors into bioactive vitamin D3 and intensive purification, we obtain a D3 crystallisate with a purity of over 99%. This forms the foundation for our natural, vegan premium-quality vitamin D3 products.
Absolute Purity: No Hidden Additives
Our branded active ingredient, Sunferol® D3, is a bespoke formulation crafted exclusively for Sunday Natural from natural raw materials, with an uncompromising commitment to purity and quality. To ensure optimal dosage and stability, our premium D3 is dissolved in coconut-based MCT oil. Conventional D3 ingredients are often combined with a variety of questionable additives that do not require declaration, such as synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils and maltodextrin. Our active ingredients are produced by a specialised manufacturer using a time-intensive process that adheres strictly to our specifications. We deliberately avoid every common, hidden additive; the inherent purity of the source material allows us to include only a minimal amount of bioactive vitamin E to ensure oxidative stability, maintaining maximum potency and shelf life. To guarantee this standard, our products undergo regular independent laboratory testing for nutrient content, freshness, and potential contaminants such as heavy metals.
MCT Coconut Oil for Optimal Absorption
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.
In order to achieve an even distribution of vitamin D3 in the powder and thus an exact dosage of the tablets, a carrier must be used. We have opted for 100% nanoparticle-free microcrystalline cellulose; commercially available microcrystalline cellulose may contain up to 10% nanoparticles without requiring declaration.
The only other ingredients are premium gum arabic and the vegan amino acid L-leucine. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural food source.
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
Vitamin K2 & Vitamin D
Vitamin K2 is the most important cofactor of vitamin D in the regulation of calcium metabolism. Together, the two vitamins control bone-building as well as breaking down cells and important transport molecules that ensure the correct utilisation of calcium.
Dosage
Directions
Take 1 tablet daily with 200ml water with a meal.
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. 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.
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.
