High-dose vitamin K1

This food supplement provides you with high-dose vitamin K1 in the form of phytomenadione. One tablet contains 500µg vitamin K1.
As this is a fat-soluble vitamin, the tablets should always be taken with a meal.

Function of vitamin K1

The main function of vitamin K1 is to maintain normal blood clotting. It plays an important role in the activation of 4 so-called coagulation factors by converting them into the effective form.
The vitamin K1-dependent coagulation factors are enzymes produced in the liver which, through various functions, ensure that the blood coagulates and closes the wound in case of injury.

Vitamin K not only helps to regulate blood clotting, but also plays a role in bone metabolism and bone mineralisation. While vitamin D3 makes sure that calcium from food is absorbed well through the intestines, vitamin K1 is responsible for ensuring that this calcium does not get deposited in the blood vessels but gets to where it belongs: to the bones and teeth.

Vitamin K plays a key role in the activation of osteocalcin. This protein makes up 10 to 20 percent of total bone protein and contains γ carboxy-L-glutamic acid residues. These enable osteocalcin to bind the crystalline hydroxyapatite stored in the bone, which makes up about 60 percent of the bone substance. The formation of the necessary γ-carboxy-L-glutamic acid residues depends on vitamin K.
In colloquial language, it is therefore also called "bone vitamin" together with vitamin D.

Vitamin K1 in food

Significant amounts of vitamin K1 are found primarily in vegetable foods. The best sources are green leafy vegetables such as spinach, lettuce and kale as well as broccoli, cauliflower and Brussels sprouts. Lentils, chickpeas, oatmeal and bran are also good sources of vitamin K1.
Good animal-based sources include pork liver, eel and eggs.
