Vitamin K1, K2, And K2 (MK-7) – The Difference
vitamin k1 k2 mk-7

The calcification of the soft tissues is prevented by vitamins K1 and K2, whereby K2 has a stronger effect, especially in the form of MK7. Bone building and decalcification of the bones are also promoted by K1 and K2, together with vitamin D, C, and magnesium.

We get vitamin K1 from lettuce leaves and green leafy vegetables, ideally in combination with healthy fat (e.g., coconut oil, avocado, or butter). Fat increases absorption because vitamin K is fat-soluble, as is vitamin D.

It is currently unclear to what extent vitamin K1 is converted into K2 by the intestinal bacteria and how much is subsequently absorbed.

Apart from natto, vitamin K2 is only found in animal fat, meat, milk, and butter, provided the animals have grazed on green meadows. The green herbs in the food are important. But even then, it is uncertain whether meat and butter will cover the basic need for K2. To prevent a deficiency, it is advisable to supplement vitamin K2 MK7: normally at least 100 micrograms per day; in the case of osteoporosis, calcified arterial walls, and calcified kidneys, it is better to take 200 micrograms. This not only prevents further calcification of the soft tissue, it can even reverse the calcification, although this process takes years. Vitamin K1 is also helpful in this regard but less effective than K2.

During treatment with anticoagulant drugs, the Quick value remains unchanged when taking a vitamin K2 supplement (this provides information about the ability of blood clotting). This does not apply to vitamin K1 because vitamin K1 activates factors that promote and inhibit coagulation.

Nevertheless, even a well-dosed supply of vitamin K1 promises advantages in stabilizing blood clotting. Treatment with anticoagulant drugs (vitamin K antagonists) poses a risk of accelerated calcification of the vessel walls. Vitamin K2, in combination with vitamin D and magnesium, helps against this.

A higher intake of vitamin K1 through food is associated with a higher life expectancy. Even people with advanced arteriosclerosis have a lower risk of heart attack and death with vitamin K. Therefore, any restriction of vitamin K intake should be viewed critically.
