Vitamin K2-MK7

Superior absorption of MK-7 in a double micro-encapsulated, soy-free formula

While vitamin K1 (phylloquinone) is best known for its role in blood coagulation, it’s not the kind of vitamin K we need to support proper calcium deposition. It’s vitamin K2 (menaquinone) that plays an essential role in the development and maintenance of the human skeleton by activating two key bone proteins: osteocalcin and matrix GIa protein (MGP). In this way, vitamin K2 supports strong bones by regulating calcium deposition into the bone mineral matrix.

About Vitamin K2-MK7

It’s vitamin K2 that directs calcium to where it’s supposed to go—instead of where it doesn’t belong. Since K2 appears to keep calcium from depositing in soft tissues, it may have a protective role against coronary artery disease by helping maintain arterial flexibility.

Heart disease, bone fractures, pain and cognitive decline don’t have to be part of the aging process. These preventable conditions are all associated with dysregulated calcification—in other words, calcium deposition in places where it shouldn’t be happening, instead of where it should. When calcium is deposited into the arteries and joints instead of into the bones, it can trigger the development and/or exacerbate chronic disease, reducing quality of life. For these reasons, vitamin K2 supplementation can be a valuable part of any lifestyle.

Is your diet a reliable source of vitamin K2? Generally, the vitamin K in foods is poorly absorbed, with the small amount that’s absorbed being rapidly metabolized and excreted by the body. This necessitates replenishment every few hours to maintain blood levels.

Add to this the fact that vitamin K2 is present in foods in very small amounts, as the inferior MK-4 form, and in just a few obscure foods. For example, while it’s true that vitamin K2 is found in certain fermented soy-based foods as the preferred MK-7 form, availability and use of these products in North America is modest at best. Plus, soy allergy/intolerance is increasingly common.

Combine all these facts and it becomes obvious that supplementation of Pure Lab Vitamins K2 - MK7 is the better way to ensure consistent blood levels of vitamin K2.

Why is Pure Lab Vitamins K2 - MK7, not MK4? Research shows that compared to the MK4 form used in some vitamin K2 supplements, MK7 is the most bioavailable. That’s why Pure Lab Vitamins K2 - MK7 consists exclusively of dry form MK7—the most efficiently absorbed, stable form of vitamin K2. It is double micro-encapsulated using a unique process that ensures compatibility with food and supplementary doses of minerals and a long shelf-life.

Our MK7 is dry form, long-lasting, soy-free, and extracted from rose and geranium oils.
