Vitamin K is a nutrient that the body needs in the process of blood clotting. Vitamin K is contained naturally in foods and is available in supplement form.
Vitamin K was first discovered in Denmark (1964), when it was discovered that chicks fed fat-free rations, were found to show symptoms of hemorrhage. In infants, hemorrhage can be prevented by giving vitamin K to the mother before the baby is born. Based on this reason, vitamin K is also called vitamin coagulation, because it plays a role in maintaining the consistency of blood flow and clotting it when needed.
The main sources of vitamin K are vegetables and fruits. Types of vegetables that contain vitamin K include kale, spinach, broccoli, radish, mustard, and cabbage. While some types of fruits containing vitamin K are avocados, figs, kiwi, pomegranate, and grapes.
Although not as much as in vegetables, vitamin K can also be found in fish, meat, liver, and egg yolks.
The main function of vitamin K is to help the blood clotting process. If the body is deficient in vitamin K, blood will be difficult to clot. As a result, people who are deficient in vitamin K will easily experience bleeding. Vitamin K deficiency is more common in newborns than older persons.
Vitamin K types
Vitamin K is found in three different forms. The first is vitamin K1 or phylloquinone, which is a type that plants find and produce. The second is K2 or also called menaquinone, which is produced by beneficial bacteria in the digestive system. And the third is K3 or menadione which is an artificial vitamin for those who are unable to absorb from food.
All vitamin K in your body is processed in the liver, where it will later be used to produce substances that make your blood clot. In addition to playing a role in clotting, this vitamin is also important for bone formation especially type K1. Vitamin K1 is necessary so that the absorption of calcium for the bones becomes maximal and ensures that it is not mistargeted.
Chemical properties of Vitamin K
Vitamin K is found in the natural fat soluble, but some synthetic preparations are water soluble. 2-Methyl-1,4-nafrakuinone, also known as menadione, is a synthetic product of vitamin K, which is more active than vitamin K1.
Vitamin K Use
Vitamin K can be used for a variety of treatments. This vitamin, has two forms, namely K1 (phytonadione) and vitamin K2 (menaquinone). However, vitamin K1 is more commonly used because it is safer, can work quickly, powerfully, and better in some conditions. Vitamin K is useful for the process of blood clotting, preventing vitamin K deficiency, and treating osteoporosis (weakening of bones).
