Vitamin K and vitamin D play an important role in bone maintenance

Healthy bones are important at any age because they form the skeleton of our body. In addition to the mineral calcium, vitamin D and vitamin K also play an important role in bone maintenance.

The high-dose tablets of Doppelherz Vitamin K2 + D3 2000 I.U. are recommended for people who want to ensure their supply of the "sun vitamin" vitamin D.

• Vitamin D and K contribute in interaction to the maintenance of healthy bones.
• Vitamin D contributes to the normal absorption and utilization of calcium. Thus, it serves as an "incorporation helper" for the bone mineral calcium absorbed from food.
• Vitamin K + D contribute to the maintenance of healthy bones.
• Vitamin D contributes to normal blood calcium levels.
• VitaminK contributes to normal blood clotting.
• Vitamin D contributes to the maintenance of normal muscle function and contributes to the maintenance of normal immune system function.

The easy-to-swallow mini tablet from Doppelherz contains 100 μg vitamin K in the form of menaquinone (MK-7). This is a high-quality vitamin K2 and can be well absorbed by the human body. In addition, the mini tablet contains 50 μg of vitamin D, which corresponds to 2000 I.U. (International Units).

Vitamin D for bones, muscles and immune system

Our immune system, like all organs and cells of our body, depends on nutrients to perform at its best at all times. Along with vitamin C, vitamin D has made a name for itself here because it supports the normal function of the immune system.

We absorb vitamin D in part by eating foods like fish, eggs and dairy products. But our bodies can make vitamin D on their own through the influence of enough sunlight on our skin. However, the sun rarely appears in the autumn and winter months.

However, vitamin D is also coming more and more into focus in connection with bone health: It supports the normal absorption of calcium and the normal calcium level in the blood and thus contributes to the maintenance of normal bones.

Vitamin K - for blood clotting and bone health

Like vitamin D, vitamin K plays a role in numerous bodily functions. It has long been known that vitamin K contributes to normal blood clotting. This is why the vitamin also bears its name: "K" for coagulation (clotting).

Another role of vitamin K is in bone health. By helping to mineralize the skeleton, vitamin K, like vitamin D, helps maintain normal bones.

Vitamin K2 Menaquinone MK-7

In turn, vitamin K2 can be divided into several variants, for example MK-4, MK-5 or MK-7, whose number of chemical side chains is different.
These variants differ from each other both in biological activity and bioavailability, with MK-4, for example, being very poorly absorbed in the intestine.

The vitamin K2 MK-7 used by Doppelherz is considered the best-known variant and is well absorbed by the human body.

Vitamin K1 and K2 in food

The fat-soluble "vitamin K" is not a single vitamin, but occurs in nature in the form of vitamin K1 (phylloquinine) and the group of K2 vitamins (menaquinones, abbreviated MK).

Vitamin K1 is mainly found in green plants such as lettuce or cabbage, where it plays a decisive role in photosynthesis.

Vitamin K2 is also known as "bacterial vitamin K" because it is produced by microorganisms. On the one hand, it can be produced in small quantities by intestinal bacteria themselves and transported into the blood. However, it is assumed that this self-production is not sufficient.

On the other hand, animal and bacterially fermented foods are considered sources of vitamin K2, but the content is usually not particularly high.
The decisive factor for the vitamin K content of fermented foods, e.g. yogurt, cheese or sauerkraut, is which bacterial strains are used for preservation.
Incidentally, Natto, a fermented soybean product from Japan that is hardly known in Germany, is probably the food with the highest vitamin K2 content.
