From what sources can you get vitamin K?

Discovery history

Scientist Henrik DamHenrik Karl Peter Dame in 1928 studied the effects of a cholesterol-free diet in chickens. For this he was able to get the Nobel Prize. The result of his work was the identification of vitamins, which the world did not yet know - the group K.

Chickens, deprived of food with cholesterol, quickly lost their health. Several weeks of such a diet led to hemorrhagic diseases, spontaneous hemorrhages under the skin, other organs and tissues. After that, he began to add foods high in cholesterol to them, but hemorrhage was not eliminated!

Gradually, he came to the conclusion that the desired substance is in products of plant origin, for example, in cereal grains. They also increased blood clotting. The publication of an article titled "Koagulations vitamin" (German: coagulation, blood clotting) helped give a name to this group of substances.

The baton from Henrik Dame took the Swiss Carrera - in 1939, he isolated from vitamin alfalfa vitamin K1, called phylloquinone.

During this period, another substance was found with the same effect, but with different properties, called K2 (menaquinone, menateterone). It was synthesized from ground waste from fish processing by the Americans Binkley and Doisy.

Why does the body need it?

Blood clotting processThis substance is indispensable in the process of blood coagulation, it participates in the formation of prothrombin, protein C, S and Z, which exhibit antihemorrhagic properties. Some protein structures are formed only under the influence of this vitamin and are located in the heart and lungs.

Vitamin K is involved in the purification of the cardiovascular system of the body.

Vitamin is useful in bone metabolism. These properties are due to its ability to bind and help absorb calcium, it also provides the interaction between calcium and vitamin D. Without it, metabolic processes in the bones do not cost. It follows that he:

  • ensures normal growth of the child’s skeleton;
  • responsible for the health and function of the kidneys;
  • antitumor agent;
  • normalizes energy metabolism (this vitamin exhibits anabolic properties).

Sources of Vitamin

The main key to vitamin K is our own body.It is formed in the small intestine during the operation of Escherichia coli, then it is stored in the liver, and then disintegrates from exposure to light and in alkali solutions.

Contained in the following main products:

  • Broccoligreen vegetables (in spinach, cabbage, lettuce);
  • soy products;
  • cereal;
  • dairy products;
  • in some fruits (kiwi, bananas);
  • meat;
  • olive oil.

Vitamin K deficiency and excess

Shortage develops in the following cases:

  • with the problem of digestion of the gastrointestinal tract
  • hepatitis, cirrhosis and other liver damage;
  • in pancreatic oncology;
  • with an overdose of anticoagulants;
  • if you are taking medications that weaken the action of group K or directly opposite them (these may be vitamins of group E, dimumarin, fenvidione);
  • frequent intake of alcohol, carbonated drinks, food with flavors and preservatives may reduce the absorption of the vitamin;
  • with dysbacteriosis;
  • chemotherapy always affects the decrease in the amount of vitamin K;
  • anticonvulsant drugs;
  • with large doses of salicylates;
  • with insufficient vitamin content in foods.

There are symptoms for which K-avitaminosis can be easily detected. The most common are:

  • if even with small scratches or wounds, the blood does not stop for a long time (bleeding disorder);
  • nosebleeds;
  • problems with digestion and stool;
  • when brushing teeth, the gums bleed;
  • Knee Scratchanemia, increased weakness, as its consequence;
  • frequent bone fractures;
  • liquid feces, similar to tar, in newborns;
  • painful and prolonged critical days;
  • bruising.

Despite all the beneficial properties of vitamin K, its overabundance or deficiency can cause negative effects, for example:

Consequences of vitamin K deficiency Consequences of Vitamin K Excess
  • spontaneous hemorrhage;
  • menstrual pain in women;
  • hypothrombinemia - impaired blood clotting;
  • cartilage ossification;
  • severe deformities in the development of children's bones;
  • the deposition of salts on the walls of the arterial vessels.
  • overdose leads to an increase in platelet count;
  • hyperprothrombinemia;
  • blood viscosity;
  • tendency to thrombosis.

Indications and warnings

You can not use drugs and foods rich in vitamin K for varicose veins and patients with thrombophlebitis (inflammation of the walls of the veins and the formation of a blood clot).

Cholesterol Plaque FormationIt is also not recommended to use vitamin when the vessel is blocked with solid particles, fat or gas (embolism).

With an elevated cholesterol level, this element can contribute to the formation of a cholesterol plaque.

Another contraindication to use is individual intolerance.

Vitamin K will be useful in the following cases:

  • osteoporosis;
  • toxic, alcoholic and infectious lesions of the liver (hepatitis, cirrhosis);
  • osteopenia (loss of bone mass);
  • brittle vessels;
  • in some oncological (liver cancer, prostate) diseases;
  • a form of tuberculosis, one of the symptoms of which is bleeding ;;
  • hardening of the arteries;
  • dysproteinemia (violated quantitative proportions between the different fractions of proteins);
  • persistent diarrhea;
  • during the preparation and after such surgical operations, in which severe bleeding is possible;
  • with hemorrhagic diseases, or diseases that are accompanied by them;
  • during the last four weeks of pregnancy, drugs are prescribed to prevent hemorrhagic disorders in newborns;
  • stones in the kidneys;
  • obstructive jaundice;
  • bleeding in women associated with problems in the genital area;
  • ulcers of the stomach and duodenum, colitis and some other diseases of the gastrointestinal tract;
  • if you are taking large doses of anticoagulants or other medications;
  • muscle weakness and weakness due to anemia;
  • with bleeding during radiation sickness;
  • intestinal atony.
According to recent studies, drugs based on K2 can be a cure for Parkinson's disease.

But this group of vitamins is not well understood, so it is possible that soon we will learn about new areas of its application.

Dosage

Vicasol TabletsIf you are taking drugs for treatment, then the dose is determined by the doctor based on the specific disease and methods and methods of therapy. As a synthetic analogue, doctors usually prescribe Vicasol (C3).

If you mainly get vitamins of this group from the diet and want to know what foods it is in, then there is a special table for this.

Storage and processing of products with vitamin K

It carries storage well, but still it is not recommended to freeze it, since its content after freezing is reduced by 20-30%.

Studies have confirmed that it is not recommended to subject vitamin K to heat treatment, since it collapses at high temperatures.

But here's a funny paradox - in some cases, after heat treatment, it becomes larger. Most likely, this is due to the release of vitamin K from the chloroplasts in which it is contained. It is difficult to say exactly how to prepare it for such a reaction, so it is not recommended to expose vegetables and fruits to heat.

You should not hope to find it in factory juices. After industrial processing, not only this vitamin disappears, but also most of the others.
