Vitamin D3 drops from Edubily
Vitamin D3 is an essential nutrient that plays a crucial role in the body. It contributes to the normal absorption and utilization of calcium and phosphorus, thereby significantly contributing to the maintenance of healthy bones. The body needs vitamin D to utilize calcium efficiently. Vitamin D also contributes to the maintenance of normal muscle function and the normal function of the immune system.
Edubily uses only a few raw materials in its vitamin D range: it contains only cholecalciferol (vitamin D) and coconut oil-based MCT oil, as well as vitamin K2-MK7 in the all-trans form; no other additives. Easy to dose with the pipette: One drop contains 20 µg (= 800 I.E.) Vitamin D and 15 µg vitamin K2.

Supplemented with vitamin K2
This product also contains vitamin K. Some sources suggest that vitamin D may influence vitamin K requirements, in part because it supports the formation of certain vitamin K-dependent proteins such as osteocalcin.
For its product, Edubily uses vitamin K2-MK7 in the so-called all-trans form – a form that also occurs naturally in fermented foods. This structure is considered particularly stable and easily absorbed. Unlike synthetic mixed forms with cis isomers, studies have shown that the all-trans form is more readily available in the body and stays in the blood longer.
According to official health claims, vitamin K contributes to normal blood clotting and the maintenance of normal bones.
Frequently Asked Questions & Answers from Edubily
Does vitamin D need to be combined with vitamin K2?
Not essential, but useful. If you want a supplement without vitamin K2, then check out the Vitamin D3 as drops or capsules to.
Is vitamin D3 vegetarian or vegan?
Vitamin D3 is vegetarian, but not vegan.It is obtained from wool fat (lanolin) from sheep.
Can I add vitamin D3 to food or drinks?
Theoretically, yes, but taking it directly into the mouth is more advisable. This allows the vitamin D3 to be absorbed through the mucous membranes, which can promote more effective absorption.
How much vitamin D is in food?
Vitamin D is present in very small amounts in the diet, usually covering only 10-20% of the body's needs. Foods with significant amounts of vitamin D include fatty fish (salmon, herring, and mackerel).
It is almost impossible to cover your vitamin D needs exclusively through diet.
Isn't it enough if I stay in the sun?
The intensity of solar radiation in our latitudes between October and March is not sufficient to produce enough vitamin D. Supplementation may therefore be beneficial.
How long does the vitamin D storage from summer last?
In short: not at all. Studies show that vitamin D levels in Europe are inadequate, especially during the winter months. A 2015 study by the Robert Koch Institute found that 80% of Germans don't even reach the recommended 20 ng/ml – and 30 ng/ml is even rarer. Despite this significant undersupply, the problem is often downplayed in Germany.
What is an optimal vitamin D level?
Information on optimal vitamin D levels varies depending on the source. According to the Robert Koch Institute, a level of approximately 20 ng/ml (50 nmol/l) is considered sufficient. However, several professional societies, including the Endocrine Society and vitamin D discoverer Michael F. Holick (recent publication in Nature), recommend at least 30 ng/ml (75 nmol/l) to maximize the positive effects on calcium, bone, and muscle metabolism.
How does body weight affect vitamin D dose?
Body weight has a direct impact on vitamin D requirements. First, adipose tissue can serve as a "storage" for vitamin D, making it less available in the blood. Second, the requirement increases with increasing body mass. Studies show that severely obese people need up to two to three times more vitamin D, while overweight people should, on average, consume about 50% more.
How much vitamin D should one-year-olds get?
A recent article in the renowned journal Nature recommends a daily intake of 400 to 1,000 IU for infants up to one year. For babies and children, we also have a specially tailored preparation from Edubily in our range. This allows for safe and easy dosing for children.
Can you overdose on vitamin D?
Theoretically, yes, but in practice, this is rare. Vitamin D is one of the safest vitamins because it is naturally produced in very high amounts in the skin during the summer through sun exposure. A dose of around 10,000 IU, often considered high, can be produced by the skin in just a few minutes. The body therefore has mechanisms to cope with high doses. However, very high doses of more than 10,000 IU per day for extended periods should be avoided.
Can you take vitamin D3 during pregnancy?
Yes! Studies show that up to 4,000 I.E. per day are safe.
