Abstract
Single dose administration of MK-4 (420 μg; 945 nmol) or MK-7 (420 μg; 647 nmol) was given in the morning together with standardized breakfast. Vitamin K 2 contributes to bone and cardiovascular health. However, little is known about the bioavailability of nutritional MK-4.
Introduction
A number of blood coagulation factors including coagulation factors II (prothrombin), VII, IX, and X are well-known examples of Gla-containing proteins, which are synthesized in the liver. In food, vitamin K 1 is bound to the chloroplast membrane of leafy green vegetables. Mk-4 is derived from the conversion of menadione (synthetic analog of vitamin K only consisting of the 2-methyl-1,4-naphthoquinone ring structure), which is given to the animals.
The Japanese fermented food “natto” contains MK-7 at an exceptionally high concentration [2]. The effects of long chain MK-n such as MK-7 on normal blood coagulation is greater and longer lasting than vitamin K 1 and MK-4 [3-5].

Vitamin K2 has numerous positive properties and is able to support the body in many ways.
The dietary supplement is also able to promote strong bones and clean arteries, which is especially important, because in advanced age the calcium supply is often insufficient. Vitamin K2 is one of the fat-soluble vitamins and supports the body in maintaining the dental health. Vitamin K activates proteins, which are responsible for transporting the calcium (e.g.
Rotterdam Heart Study On Vitamin K2
4800 people who were at least 55 years old were monitored. The study came to the conclusion that all participants, who took vitamin K2 regularly, had healthy arteries and less calcium in the blood. This proves that dietary supplements containing vitamin K2 support the circulation.
This vitamin K2 supplement by Fairvital combines menaquinone MK-4 and menaquinone MK-7. Mk-4 is the fastest resorbed form of K2 and MK-7 has a very long half-life in the body.
