What do high-dose vitamin D capsules do?

Sunshine vitamin - that's what vitamin D is also called. Because it is a very special vitamin. It is the only one that our body can form itself from precursors in the skin. For this to happen, the sun's rays, or more precisely UV-B rays, must hit the skin. From around March to October, the sun is at the right angle in this country to provide enough energy for vitamin D formation. In winter, on the other hand, our body is dependent on vitamin D stores and food. But this is not so easy, because only a few foods contain large quantities of vitamin D. These include mainly animal products such as fish.

For people who eat a vegetarian or vegan diet, this gap can be closed by vitamin D3/ K2 capsules. But the vitamins can also be used in other situations. For example, vitamin D formation in the skin decreases with age and the risk of a deficiency increases. People who rarely or never go out in the sun with their skin uncovered (e.g. if they have a sun allergy) find it difficult to meet the daily requirement of 20 µg.

But what does the body actually need vitamin D for? The best-known function of the vitamin is its contribution to the maintenance of normal bones and teeth. But it also contributes to the normal function of the immune system, has a function in cell division and supports the normal absorption and utilisation of calcium and phosphorus. It is also important for the maintenance of normal muscle function.

Why shall i take D3 and K2 together?

The fatty vitamin D (calciferol) is divided into vitamin D2 (ergocalciferol) and D3 (cholecalciferol). Both are active compounds with comparable effects in humans, but vitamin D2 has only 25 to 30 percent of the biological activity of vitamin D3. Vitamin D2 is usually found in plant products and vitamin D3 in animal products.

Vitamin K is also not just one compound, but a variety of similar molecules. Vitamin K1, for example, is found in green leafy vegetables, vitamin K2 (menaquinones) in fermented products and vitamin K3 can only be produced chemically. There are 14 different forms of vitamin K2 alone. Compared to K1, which is mainly found in the liver, the highly effective form vitamin K2 MK-7 accumulates better in various tissues. In the body, vitamin K contributes to both normal blood clotting and the maintenance of normal bones.

If vitamin D3 is taken in high doses, then vitamin K2 MK-7 should not be missing, because otherwise a vitamin K deficiency could occur. The positive influence of vitamin D on the incorporation of calcium into the bones can then even be reversed. In addition, it is assumed that the vitamins in combination prevent plaque deposits in the blood vessels, which can result from high doses of vitamin D. That is why we are convinced of vitamin D3/ K2 capsules in combination, because they offer a possibility for well thought-out vitamin D supplementation.
