Vitamin K is a fundamental micronutrient for the human body. As part of the fat- soluble (fat-soluble) vitamins, vitamin K comes in three different forms:
The first is known as phylloquinone, or vitamin K1. It is found in plants and is best absorbed when consumed with fat.
Another form is menaquinone, or K2, produced by bacteria in the intestine. It is absorbed only in small quantities
Finally, vitamin K3, or menadione, is more potent than K1 and K2, but it is only synthesized in the laboratory and is found in supplement form.
But, after all, what is vitamin K for? Why is it essential for our body and where can we find it? Continue reading and understand!
What is vitamin K good for?
Vitamin K has two main functions in the human body:
Regulating blood clotting
Like other fat- soluble vitamins, vitamin K assists in protein synthesis . In this case, proteins synthesized with the aid of this vitamin have the function of controlling bleeding and regulating blood clotting.
Promote bone health
Vitamin K also plays an important role when it comes to bones. It helps in fixing calcium in the bones, which makes them more resistant. So, like calcium and vitamin D, vitamin K is an ally to prevent diseases such as osteoporosis .
What are foods with vitamin K?
Vitamin K is produced in the human body, but not in sufficient quantities. Therefore, it is important to have a diet that guarantees its presence in the processes in which it is essential.
This micronutrient can be found in some vegetables and also in meats. Below, we have separated the foods that most contain vitamin K:
|Food||Portion||Amount of vitamin K|
|Cooked Brussels sprouts||78g||460µg|
What happens to a lack of vitamin K?
If the amount of vitamin K in the body is insufficient, problems can occur, mainly related to blood clotting. As a result, bleeding and bleeding may be more difficult to control. There may also be internal bleeding, weakening of nails, bones and cartilage.
Vitamin K deficiency in healthy adults is rare. Usually, it is caused by the use of some medication that influences its performance, as is the case of some antibiotics .
It is more common for children to be absent, especially premature babies. In such cases, vitamin K supplementation may be necessary.
On the other hand, the excess presence of vitamin K can cause liver disease and hemolytic anemia (when red blood cells are destroyed). Overdosing is rare, and usually occurs due to over-supplementation.
Vitamin K is a fundamental micronutrient for blood clotting and bone formation.
Therefore, it is essential to have an adequate consumption of this vitamin, since the K1 type is not produced in sufficient quantities by us.
