Types, needs, sources, deficiency and toxicity symptoms of Vitamin K

Types, needs, sources, deficiency and toxicity symptoms of Vitamin K. This vitamin is a vital requirement for the synthesis of several proteins including the clotting of blood. Also called the coagulation vitamin, this vitamin is responsible for maintaining consistency and freeze the blood flow when needed. Fat-soluble vitamins also play an important role in bone formation and maintenance of the kidney.

This type of Vitamin K

Vitamin K found in three different forms. The first is vitamin K1, or phylloquinone, is found and the resulting types of plants. The second is referred to as K2, or menaquinone, which dihasilan beneficial bacteria in the digestive system. And the third is a K3 or menadione is a vitamin made for those who are unable to absorb from food.

The entire vitamin K in your body is processed in the liver which will be used to produce substances that can make your blood freeze.Besides a role in clotting, this vitamin is also essential for bone formation, especially the type K1. Vitamin K1 is required so that the absorption of calcium for bones to be maximized and ensure it is not misplaced.

Vitamin K Cycle

As a cofactor to the carboxylase It produces gamma-carboxyglutamic acid, vitamin K has oxidation and reduction cycles COMPANY That Allows reuse. Important details of this cycle are:

Vitamin C (Normally K1) with Reduced vitamin KH2.

Oxygenation of vitamin KH2 provide energy to drive the carboxylation reaction, causing the formation of gamma-carboxyglutamic acid residues and the vitamin K oxide.

Vitamin K Oxide is Reduced by the others returned to vitamin K reductase, ready to enter another cycle. Warfarin anticoagulation dry and block the reduction of vitamin K to vitamin K oxide, explaining their antagonistic effect on this cycle

How much Vitamin K?

According to the standard RDA (Recommended Dietary Allowance), vitamin C a person needs depends on the weight. For adults, it requires at least 1 microgram per day per kg of body weight. So, if you weigh 50 kg then the need to reach 50 micrograms per day.

Sources of vitamin K

To meet the needs of vitamin K is quite easy because in addition to relatively small numbers, our digestive systems contain bacteria that can synthesize vitamin K is partially absorbed and stored in the liver. But once the body also need to get extra vitamin K from food.

Most sources of vitamin K in the body is synthesized by bacteria in the digestive system, but you can get vitamin K from foods such as liver, vegetables, green leafy, cruciferous vegetables cabbage (cabbage) and milk.Vitamin K is found in high concentrations in soy milk, green tea, milk cows, and beef and liver. The types of probiotic foods like yogurt that contains active healthy bacteria, can help stimulate the production of this vitamin.

Deficiency symptoms of vitamin K

If vitamin K is not contained in the body, blood can not clot. This can cause bleeding or hemorrhagic. However, vitamin K deficiency is rare because almost all orag get it from bacteria in the gut and from the food.

But the flaws can occur in infants because their digestive system is sterile and does not contain bacteria that can synthesize vitamin K, breast milk contains only small amounts of vitamin K. For the infants were given a vitamin K at birth.

In adults, deficiency can occur due to lack of consumption of vegetables or taking too long antobiotik. Antibiotics can kill beneficial bacteria in the gut that produce vitamin K. Sometimes vitamin K deficiency caused by liver disease or digestive problems.

Vitamin K toxicity

You can also experience toxicity vitamin K. This occurs only in people who receive a water-soluble vitamin K replacement. The symptoms are the hemolysis (destruction of red blood cells), jaundice and brain damage.Variety of sources.
