Valens K2 oral spray

Description

Valens K2 (Keovon) is a convenient dietary supplement in the form of an oral spray that allows good absorption as well as easy and accurate dosing of this extremely important vitamin. Vitamin K contributes to the normal coagulation of blood and the maintenance of healthy bones. Valens K2 oral spray contains a natural form of vitamin K2 – menaquinone-7, which is obtained by fermentation. It is one of the highest quality forms in the world, produced in the European Union. Vitamin K2 MK-7 is extremely well absorbed, and studies show that it remains in the bloodstream for up to three days.

The difference between K1 and K2

Phylloquinone (vitamin K1) is a form of vitamin K whose source are plants, mainly dark green vegetables, while menaquinones (vitamin K2) are of bacterial origin. We know a lot of different menaquinones, which we name according to the length of the side chain. The vitamin is most commonly found in the forms mk-4 (short chain) and mk-7 (long chain, produced by bacteria).

Studies have shown that vitamin K1 (phylloquinone) is poorly absorbed by the body and also disappears from the body after just a few hours. In contrast, vitamin K2 in the form of mk-7 is extremely well absorbed and remains in the bloodstream for up to 3 days, which leads to the intake of menaquinones leading to higher plasma vitamin K concentrations.

Sources of vitamin K

The main sources of vitamin K in the western world are green vegetables, where vitamin K is found in the form of phylloquinone (vitamin K1). Vitamin K1 is rich in spinach, broccoli, brussels sprouts and cabbage, as well as some vegetable oils and margarines. Meat, milk, dairy products and eggs contain lower concentrations of vitamin K than vegetables, but in the form of menaquinones (vitamin K2). Very high concentrations of menaquinones are found in natto, a typical Japanese fermented soy product. To some extent menaquinones can also be produced by bacteria in the gut.
