- Fights the common vitamin K deficiency, helping with several health problems.
- Plays a part in activating certain coagulation factors.
- Helps to redistribute calcium within the body to the bones and teeth.
Complete K is a supplement containing vitamins K1, K2 MK-4 and K2 MK-7, for a complete and optimal delivery of vitamin K in vegetarian capsules, now available to buy at Supersmart.
The term vitamin K covers various substances that play a part in activating certain coagulation factors (or ‘Koagulation’ in German). Having reached the lymphatic vessels, vitamin K is taken up by chylomicrons and accumulates in the liver where it participates in the synthesis of four coagulation factors, including factor II (prothrombin) and its conversion into thrombin.
Having said that, research by Dr Rhéaume-Bleue has revealed that 80% of Americans are deficient in vitamin K2, potentially leading to brain disorders, cancer, stroke, kidney stones or osteoporosis. Taking Complete K is therefore essential for those with:
Scientists at Maastricht University have even demonstrated that many healthy people are lacking in vitamin K and that supplementation may be beneficial for those aged over 40. However, it applies especially to:
It is now known that vitamin K2 remains active for a long time in the body (up to 72 hours), at very low doses, while being ten times more bioavailable than vitamin K1. It also acts synergistically with a number of nutrients such as vitamin E and calcium. However, the biological role of vitamin K2 extends still further:
Up until the last few years, it was thought there was only one form and one active family of vitamin K, represented by vitamin K1 (phytomenadione or phylloquinone). This is the form found primarily in plants and cruciferous green vegetables such as cabbage, parsley, spinach and lettuce. It is fat-soluble and heat-stable but sensitive to light and alkaline environments.
Other forms of vitamin K, essentially vitamin K2, which is divided into two forms – MK4 and MK-7, have recently been the subject of important studies which have highlighted new properties beyond the well-established role in blood clotting mechanism.
Menaquinones (vitamin K2) are synthesised by bacteria in the intestinal tract, but they are unfortunately totally eliminated in faeces rather than distributed to vessels, bones and various tissues. K2 vitamins are also found in offal, meat, fermented products such as certain cheeses, and especially natto, a traditional Japanese food made from fermented soybeans, which is by far and away the richest source of vitamin K2 but is unfortunately not part of the Western daily diet.
There is also a synthetic form, vitamin K3 (menadione) which is rarely used since it interferes with the cells’ antioxidant defences and can cause oxidation of cell membranes. In babies, it can destroy red blood cells, leading to anaemia. Those wishing to supplement with vitamin K should, therefore, do so with both the K1 and K2 forms.
