Function of Vitamin K for Infants to Adults

The function of vitamin K not only helps the blood clotting process, but also has other important functions. You have to make sure that your daily vitamin K needs are well met so that your body stays healthy.

An easy way to meet the daily needs of vitamin K is to eat foods that contain vitamin K, such as kale, spinach, turnip, mustard greens, green lettuce, broccoli, cauliflower, fish, liver, meat and eggs. By consuming these foods, vitamin K needs can be fulfilled properly so that various functions of vitamin K for health can be obtained.

Various benefits of vitamin K for health

The main benefits of vitamin K are to support blood clotting. According to the National Institutes of Health (NIH), until now there really isn't enough scientific evidence to support the benefits of other vitamin K in addition to blood clotting.

However, from several existing studies show that vitamin K can help prevent and overcome other health problems. For example:




  • Bone health. Some studies show that vitamin K helps maintain bone strength, increases bone density, and reduces the risk of fractures.
  • Brain cognitive function. Increased levels of vitamin K in the blood have been linked to increased cognitive function in older adults so that it can help prevent senility in old age.
  • Heart health. Vitamin K can help keep blood pressure low by preventing mineral formation in the walls of blood vessels, which are the main risk factors for heart disease. In addition, adequate intake of vitamin K has also been shown to reduce the risk of stroke.

Amount of Vitamin K Needed by the Body

Everyone's vitamin K needs are different. Babies under 1 year of age, recommended vitamin K intake is 0.002 mg - 0.025 mg. Children aged 1 - 8 years, recommended intake of vitamin K as much as 0.03 - 0.05 mg. While in adults, the need for vitamin K per day can be calculated based on the kilogram of body weight that is owned.

For each pounds of adult body weight, it takes around 0.0005 mg of vitamin K. If an adult has a body weight of 122 lb, then the person's vitamin K needs are 0.055 mg daily. Meanwhile, an adult with a body weight of 205 lb, requires an amount of vitamin K as much as 0.095 mg every day.

To get the amount of vitamin K needed, you need to eat a varied and balanced diet. Don't worry too much if you consume too much vitamin K. Until now, there have been no studies that provide adequate evidence that there is a negative effect if the body has excess vitamin K.

The good news, sometimes not meeting the quota needed is also not a problem. Because, vitamin K that enters the body is not directly used. When these compounds enter, vitamins will be stored in the liver for future use. However, it would be wiser to fulfill it as needed because balance is always better than too little or too much.

What happens if someone is deficient in vitamin K

Without enough vitamin K, your body cannot produce prothrombin, which is a special protein that functions for blood clotting and bone metabolism. If this happens, you will find it easier to experience bruising even if only a minor injury. Vitamin K deficiency also makes you more prone to bleeding and difficult to heal, even if only a small scratch. The reason is, your blood becomes difficult to freeze when your body doesn't have enough prothrombin.

Not infrequently, bleeding that does not heal can have serious consequences, especially if the injury is quite severe.

Vitamin K Important Function

Some of the following are functions of vitamin K for the body that should be known:

Prevent bleeding diseases in newborns

Newborns have very little vitamin K levels, because this vitamin cannot penetrate placental tissue. In addition, newborns do not have bacteria that help the process of vitamin K formation in the digestive tract. This can increase the risk of haemorrhagic disease of the newborn (HDN) or bleeding disease in newborns, which can cause damage to the baby's brain due to bleeding. Therefore, newborns are strongly advised to get injections of vitamin K.

Accelerate wound healing

One of the important functions of vitamin K is for blood clotting. If the body does not have enough vitamin K, even a small wound can take a very long time to heal.

Build and strengthen bones

In addition to helping the blood clotting process, the next function of vitamin K is to build and strengthen bones. A medical study states, there is a connection between the low level of circulation of vitamin K in the body with a low density of a person's bones.

There are various functions of vitamin K that are important for the body. It is recommended to eat a variety of foods with balanced nutrition to meet these vitamin needs. If you want to take vitamin K supplements, make sure the amount is not excessive. To be more accurate, you should consume these supplements after consulting with a doctor.
