What is vitamin K

The human body needs less, newborns are vulnerable to a lack of vitamin K, is to promote normal blood coagulation and bone growth of the important vitamin. Dark green vegetables and yogurt are easy access to the diet of vitamin K stores.

 

The requirements of human vitamin K is very small, but it is to maintain normal function of blood coagulation, reducing physiological period of heavy bleeding, but also to prevent internal bleeding and hemorrhoids. Frequent nosebleeds person should be more from the natural food intake of vitamin K.

 

Vitamin K is divided into two categories, one category is fat-soluble vitamins, namely vitamins extracted from the green plants K1 and intestinal bacteria (such as E. coli) synthesis of vitamin K2. The other is water-soluble vitamins, namely, by the synthetic vitamin K3 and K4. The most important is that vitamin K1 and K2. To absorb fat-soluble vitamin K need bile to help, water-soluble vitamin K absorption without bile.

 

Physiological function

 

Vitamin K control of blood clots. Vitamin K is the four kinds of blood clotting proteins (prothrombin, change the speed factor, anti-hemophilia factor and Stuart factor) in the liver synthesis of essential substances. A lack of vitamin K would be delayed blood coagulation; neonatal hemorrhage caused by a large number even if the supply of vitamin K1 and vitamin K2 is also a natural form is not toxic.

 

Recommended amount of day

 

Group Age (years) Vitamin K (micrograms)

 

Infant 0 - 1 10 - 20

 

Children and adolescents 1 - 11 11-60

 

11 and above 50 - 100

 

Adults 70 - 140

 

Food Sources

 

* Beef liver, cod liver oil, egg yolk, cheese, yogurt, yogurt, seaweed, alfalfa, spinach, cabbage, lettuce, broccoli, peas, parsley, soybean oil, Spirulina, lotus root

 

Supply Notes

 

* The damage to the liver function, patients with liver disease should not be taken;

 

* A large number of pregnant and lactating women to avoid taking vitamin K supplements;

 

* X-ray, radiation, freezing process, aspirin and air pollution are the natural enemies of vitamin K;

 

* If the use of antibiotics, resulting in decrease in the number or function of intestinal bacteria reduction of vitamin K will be relatively insufficient;

 

* At the same time intake of vitamin K (even if the source of natural food), anti-blood coagulant effects of the medicine will have the opposite effect;

 

* After taking vitamin K supplements, if the face flushed, hair rash, gastrointestinal discomfort, skin, tickle and other allergic symptoms, should be immediately suspended and requested the physician diagnosis and treatment.

 

Main function

 

* The prevention of neonatal bleeding disease;

 

* Prevention of hemorrhage and hemorrhoids;

 

* Reduce the physical period of heavy bleeding;

 

* To promote normal blood coagulation.

 

Deficiency symptoms

 

* Neonatal bleeding diseases, such as vomiting blood, intestines, umbilical cord and circumcision bleeding site;

 

* Adult abnormal blood clotting, resulting in nosebleeds, hematuria, bleeding, and bleeding and other symptoms;

 

* Low prothrombin disease, symptoms of blood clotting time prolonged, subcutaneous hemorrhage;

 

* In children with chronic enteritis;

 

* Tropical diarrhea.

 

Demand for ethnic

 

* Recurrent epistaxis persons;

 

* Recent severe burns or trauma persons;

 

* Are taking antibiotics;

 

* Premature infants;

 

* The lack of adequate absorption of fat by bile (will be through the injection of additional);

 

* Patients with chronic cholecystitis.

 

Day dose

 

* Baby because bacteria can assume that there is no intestinal synthesis of vitamin K, proposing that the food intake per kilogram of body weight 2mcg amount of the average adult is about one day from the food intake per kilogram of body weight 1mcg ~ 2mcg the amount was sufficient.

 

Metabolic absorption

 

Vitamin K absorption from the intestine into the lymphatic system or the hepatic portal circulation, after absorption of chylomicrons combined to make it transported to the liver, the last mainly in the form of urine and feces discharged. The absorption of vitamin K depends on the normal function of the pancreas and biliary who can affect the absorption of fat (for example, dietary mineral oil, pancreatic exocrine dysfunction, bile stasis) would damage the intestinal absorption of vitamin K. The absorption rate of change in a wide range, in 10% and 80%, depending on the source of vitamin K, vitamin K, and the excipients.

 

Basic properties

 

Vitamin A, yellow, oily liquid or solid, soluble in oils and fats. Be able to control blood clotting, green vegetables and higher levels.
