Vitamin K belongs to – just like Vitamin A, Vitamin D, and Vitamin E to the group of fat-soluble vitamins. In the body, it is particularly important for the blood clotting of importance: Vitamin K deficiency, may occur more bleeding. If such a defect is commonly found in newborn babies, which is why they are generally supplied in the framework of the first screening with Vitamin K. In healthy adults, Vitamin K deficiency can be easily prevented, because the Vitamin is contained in many foods.
Vitamin K: Important for blood clotting
Vitamin K plays in our body, mainly for blood clotting a Central role: namely, It is involved in the production of proteins, as clotting factors for bleeding to be stopped. Vitamin K in the liver is responsible for ensuring that inactive precursors of these clotting factors are activated. No Vitamin K in the body is present, can not be converted to the clotting factors thus.
In addition, Vitamin K is also essential for metabolism in the connective tissue and the bone of meaning. Together with Vitamin D and several proteins, Vitamin K ensures that the bones are strengthened: as a result, the risk decreases for a bone fracture and osteoporosis. But not only on bone but also on the cardiovascular System should have a Vitamin K is positive in that it protects against calcium deposits in the arteries.
Vitamin K: found in food
The daily requirement of Vitamin K is 65 to 80 micrograms. Particularly rich in Vitamin K are green vegetables. The daily dose of Vitamin K, for example, is found in the following foods:
- 10 Grams Of Parsley
- 15 Grams Chives
- 20 Grams Of Spinach
- 25 Grams Of Sprouts
- 90 Grams Of Veal Liver
- 220 Grams Of Quark
- 400 Grams Of Champions
In addition, Vitamin K is also found in foods such as milk, Sauerkraut, lettuce, tomato, chicken meat, beans, and peas contain. Food with Vitamin K should be protected from light and stored, otherwise the vitamin content of the food can reduce. The losses during cooking, however, are only low because Vitamin K is very heat-stable.
In General, the intake of Vitamin K is through food, is sufficient. In the case of an increased bleeding tendency, as well as in osteoporosis, the intake of food supplements with Vitamin K, however, makes sense.
Vitamin K deficiency is rather rare
A Vitamin K deficiency is relatively rare, because Vitamin K is found in many foods and also from our gut flora itself can be formed. A Vitamin K deficiency, this is due mostly to the intake of certain drugs and not to an incorrect diet.
Thus, people with liver diseases and disorders of the digestive system, and cancer patients are particularly vulnerable to get a Vitamin K deficiency. If necessary, you should also take Vitamin K supplements. In addition, can also occur due to a long-term treatment with antibiotics, a Vitamin K deficiency because antibiotics, the intestinal bacteria are destroyed.
In addition, babies of Vitamin K are most affected deficiency, since breast milk contains little Vitamin K. In addition, the intestinal flora of babies is not yet fully developed, so that you yourself can only produce little Vitamin K. That’s why newborns receive in addition to the Vitamin K drops.
Typical symptoms of Vitamin K deficiency slow blood clotting and increased bleeding tendency. This is shown by frequent nosebleeds and a tendency to bruises.
Vitamin K for babies
Newborn will come directly to Vitamin K in the rule, after birth was administered (Vitamin K prophylaxis), since they are with low Vitamin K supplies in the world. Babies are fully breastfed, should be given until the end of the lactation, additional Vitamin K administered.
Vitamin K can be administered to the newborn either orally or as an injection. In Germany, Vitamin K will be given today orally in the Form of drops, injections to get born in, as a rule, only in the morning. The Vitamin K drops are administered to the babies in the context of the first three examinations. In other countries, it is preferably, however, an injection to achieve with a gift of the full protection.
Vitamin K Antagonists
In people who have an increased risk of thrombosis, and inhibited the formation of Vitamin K by drugs. These drugs, which include coumarins, such as Phenprocoumon or Warfarin, are referred to as Vitamin K antagonists and belong to the group of the anticoagulants (blood clotting inhibitor). Among them, Marcumar®, Phenpro Ratiopharm® or Falithrom for example,®. You will be administered, among other things, patients with an artificial heart valve or atrial fibrillation.
Vitamin K antagonists prevent the coagulation factors are converted from their inactive precursor into its active Form. As a result, the risk of a reduce blood clots. By a Vitamin K-rich diet can lower the effect of Vitamin K antagonists, however, be minimized.
Entirely on Vitamin K-containing foods does not have to be, but nevertheless – in case of doubt, should be increased after consultation with the attending physician the dose of the blood coagulation inhibitor easily. Additional Vitamin K supplements should be at the taking of a blood clotting inhibitor is not the case.
Overdose of Vitamin K
An Overdose of Vitamin K occurs only very rarely, since this Vitamin has no toxic effect. Very high doses are injected, it may cause an allergic skin reaction. Similarly, in some cases – especially in infants – changes in the blood composition, observed: extremely high doses, it can come to a resolution of the red blood cells (hemolysis).
