Vitamin K
Vitamin K exists as vitamin K1 (phylloquinone) and vitamin K2 (menaquinone). Phylloquinone is mainly found in plants, while menaquinone, which appears to be more active, is produced by gut bacteria, and is also found in fermented foods such as sauerkraut and the Japanese fermented soy bean dish Natto.
Vitamin K2
Vitamin K2 activates a whole series of special proteins which play a role in important metabolic processes, such as calcium transportation and utilisation; blood clotting; cell division, differentiation and migration; and important repair processes in various vessels and organs.
Most organisations do not consider vitamin K1 and K2 separately and, as such, there is not extensive information available on the benefits of vitamin K2 specifically. As such, our statements about vitamin K2 are based on the assumption that K1 and K2 function similarly.
According to the European Food Safety Authority (EFSA), vitamin K contributes to:
- Normal blood clotting
- The maintenance of normal bones
Vitamin K2 MK7: All-Trans from Norway
Vitamin K2 exists in various forms, each of which has a different level of efficacy. Vitamin K2 MK-7 is currently considered to be by far the most effective form of K2. However, even between different vitamin K2-MK7 active ingredients there are still considerable differences, as the vitamin molecule occurs in different chemical arrangements - we speak of so-called cis- and trans-isomers of vitamin K2. It is assumed that only the trans form can be utilized by the body at all.
Our original K2VITAL® vitamin K2 from Norway is one of the few active ingredients on the market that can guarantee 100% of the highly effective all-trans MK7 for the stated vitamin K2 content and can reliably vouch for this through a special laboratory test carried out in Norway.
Vitamin D and Vitamin K2
Vitamin D and vitamin K2 are cofactors in the regulation of calcium metabolism. Together, the two vitamins control the formation and breakdown of bone cells and important transport molecules that ensure the correct utilisation of calcium.
