The vitamin K is a nutritive material, which is in the dark-green vegetables. The Vitamin K is very important for metabolism. It was discovered in 1929 when it was noticed that the vitamin K can stop bleeding. The Vitamin K is carried with meal and some part is appeared in the human's body, in the bowel. The best sources of the vitamin K are green vegetables, as leafy tops of the turnip, the spinach, the broccoli, the cabbage and the lettuce. Other sources which have vitamin K are liver and green tea. Butter, cheese, potatoes, tomatoes are also good sources of the vitamin K. People who prefer rich food (especially sausages) should think of eating green vegetables instead.

The first symptoms of the vitamin K lack appear when something is wrong with the bowel, bleeding wounds, the nose bleeding, high fatigability.

The large quantity of medicines, dirty air can destroy the vitamin K. Every day a person needs 0.07 milligrams of the vitamin K. So, when there is a lack of the vitamin K, one need to take the liquid vitamin K. Vitamin K injections should be taken by the following people:

- People with stomach illness
- People with wrong work of the bowel
- Pregnant women
- People who suffer from chronicle diseases
- People who suffer from stress for a long time
- Newborn babies

Vitamin K injections have a higher level of the vitamin than it is in the vegetables, for example. The vitamin K is very important for newborn babies. When they are born the liquid vitamin K is given to them for preventing the hemorrhagic disease. It usually appears when the baby is about three or four days. But sometimes it happens when the child is only one day. Usually babies are born with a low level of the vitamin K. But if the pregnancy was normal and the woman didn't take any medicines usually everything goes well.

The list of risk factors is wide, so the liquid vitamin K is given to everybody, especially when the pregnancy was not normal or the woman took medicines. Newborn babies, whom only the breast milk is given, have also the risk of high vitamin K lack. Liquid vitamin K must be given to them immediately.

Vitamin K gel is also often used in the medical treatment. This treatment is connected with the skin near the eyes. The skin is thin and dry there. And wrinkles appear there firstly. So, to prevent them the vitamin K gel is used. This gel also gives eyes nice look and has the following advantages:

-the skin near eyes becomes soft and smooth
-small wrinkles will disappear
-the skin near the eyes looks younger

Sometimes it happens that there is too much of the vitamin K in the body. It is connected with the wrong work of the stomach and the bowels.

Thus, the vitamin K is one of the important ones for normal metabolism, but in some cases (cases with newborn babies) it helps to save a life and to develop normally. A lack of vitamin K lack is rare among adults because green vegetables have enough of the vitamin. One should eat less rich food. A lack of Vitamin K is often among newborn babies.
