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.
Absolute Purity: No Hidden Additives
Our branded active ingredient, Sunferol® D3 Vegan, is a bespoke formulation containing high-quality, premium vitamin D3 derived from a completely plant-based source. To ensure optimal dosage and stability, our premium D3 is dissolved in MCT coconut oil. Vitamins D is a fat-soluble vitamin that can only be absorbed by the body when combined with fats, which is why we use a particularly high-quality, coconut-based MCT oil.
The only other ingredient used as a pure, natural bulking agent is premium gum arabic (Gummi arabicum). In contrast to microcrystalline cellulose, a widely used synthetic filler often containing nanoparticles, we use a natural food source instead.
For the capsule shells, we use special HPMC capsules which, unlike most other HPMC or pullulan capsules on the market, are 100% free from the controversial but undeclared additives carrageenan and PEG. We use amber glass jars for the packaging of this product.
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 capsule (5000 IU vitamin D3) every 5 days with 200ml water at mealtimes.
Note: Not suitable for children under the age of 7.
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 a healthy lifestyle. Keep out of reach of young children.
Storage
Store in a cool, dry place away from direct sunlight and heat.
