Doppelherz Vitamin K2 + D3 1900 – For bones + calcium level + blood clotting + immune system
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 preservation.
Doppelherz Vitamin K2 + Vitamin D 1900 I.E. are recommended for people who want to ensure their supply of the “sun vitamin” Vitamin D.
Per tablet, the food supplement 1900 I.E. provides vitamin D, which contributes to the normal functioning of the immune system as well as to the maintenance of normal bones and muscle function.
Vitamin D is combined with vitamin K, which also plays a role in numerous bodily functions. Vitamin K contributes to normal blood clotting and, like vitamin D, helps maintain normal bones.
The modern combination of Doppelherz Vitamin K2 + Vitamin D 1900 I.E. contains 47.5 µg of vitamin D. This corresponds to 1900 I.U. (International Units) and 100 µg vitamin K2 in the form of menaquinone (MK-7).
Vitamin D for bones, muscles and immune system
Our immune system, like all organs and cells of our body, is dependent on nutrients to give its best at all times. In addition to vitamin C, vitamin D has made a name for itself here because it supports the normal functioning of the immune system.
We absorb Vitamin D partly through the consumption of foods such as fish, eggs and dairy products. But our body can produce vitamin D itself by the influence of sufficient sunlight on our skin. However, the sun rarely shines on our skin during the autumn and winter months.
Vitamin D is also becoming more and more important in connection with bone health: it supports the normal absorption of calcium and the normal calcium level in the blood and thus helps to maintain normal bones.
Vitamin K – for blood coagulation 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 has its name: “K” for coagulation (clotting).
A further task of vitamin K is bone health. By supporting the mineralisation of the skeleton, vitamin K, like vitamin D, helps to maintain normal bones.
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 (phyllochinin) 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 called “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 in-house production is not sufficient.
On the other hand, animal and bacterially fermented foods are considered a source of vitamin K2, but the content is usually not particularly high.
The decisive factor for the Vitamin K content of fermented foods, e.g. yoghurt, cheese or sauerkraut, is which bacterial strains are used for preservation.
Natto, a bacterially mixed and fermented soya bean product from Japan, which is hardly known in our country, is by the way the food with the probably highest vitamin K2 content.
