Pure, strong vitamin K2 dissolved in olive oil

K-Pearls contains small, soft gelatin capsules containing 75 μg of pure vitamin K2 (menaquinone MK-7) in each. Vitamin K2 is dissolved in cold-pressed olive oil to improve its absorption. Because of their size, the capsules are easy to swallow and can also be chewed. Take K-Pearls with a meal.

All-Trans MK-7
In nature, vitamin K is found in a "trans" form and a "cis" form. The individual form relates to the spatial structure of the molecule. It is only the trans form of MK-7 that is biologically active. The cis form has no biological activity. BioActive K-Pearls exclusively contain the "trans" form and are, therefore, biologically active.

Vitamin K belongs to the same group of lipid-soluble vitamins as vitamins A, D, and E.
The Danish biochemist Henrik Dam discovered vitamin K in 1929 and was subsequently awarded a Nobel Prize for his discovery in 1943. The "K" stands for "koagulation", meaning "coagulation in Danish.

There are two main types of vitamin K: phylloquinone (K1) and menaquinone (K2). A synthetic version of vitamin K called menadione (K3) is also available, but it is not usually used in dietary supplements.

Vitamin K2 is found in various forms, ranging from MK-4 to MK-14. The MK number refers to the length of the vitamin's side chain of isoprene units. Nutritional supplements usually contain the MK-7 and MK-4 forms.

Why vitamin K2 MK-7?
In contrast with Vitamin K1 and K2 MK-4, which are both rapidly metabolized and excreted, K2 MK-7 stays longer in the body and is, therefore, the most effective. We have only a small amount of stored vitamin K in the liver, spleen, and lungs.
Vitamin K and bones
Vitamin K2 is essential for the distribution of calcium to bone tissue. Bone tissue is broken down and reconstructed in a continuous cycle. Age, activity level, and diet affect this process, and we start losing bone mass when we are about 30-35 years old. The good news is we can slow down the process by making the right lifestyle choices and ensuring we have enough vitamin K2 to support calcium transport into the bone tissue.

The bone-forming cells are called osteoblasts. They produce a protein called osteocalcin that vitamin K activates. This activation is vital for transporting calcium from the blood and blood vessels and embedding calcium into the bone tissue to support normal bone function.

Vitamin K and coagulation
Vitamin K is also a key factor in the intricate coagulation process. It is necessary to form prothrombin and various coagulation factors called coagulation factor VII, coagulation factor IX, and coagulation factor X.

Animal food like meat, liver, eggs, and dairy products is the primary source of dietary vitamin K2. Fermented soy products, cheese, and sauerkraut contain a more modest quantity.

In animal foods, vitamin K2 is predominantly in the form of MK-4, whereas bacteria in fermented food mainly produce the MK-7 form.
Vitamin K1 can be obtained from vegetable sources, especially avocado, broccoli, cabbage, spinach, and green beans.

Vitamin K and intestinal bacteria
Even if fruits and vegetables contain vitamin K1 rather than K2, they still positively impact the vitamin K status. A fibre-rich diet nourishes the good gut bacteria, which in turn produce a little vitamin K2 (although insufficient to cover the body's needs). 
 

The European Food Safety Authority (EFSA) has evaluated the evidence behind vitamin K and has acknowledged the following claims:

• Contributes to the maintenance of normal bones
• Contributes to normal blood clotting
