Description: Vitamin K2

Health claims

Vitamin K contributes to normal blood clotting.

Vitamin K contributes to the maintenance of normal bones.

Vitamin K is a fat-soluble vitamin that plays an essential role in blood clotting and bone health.

Our menaquinone-7 vitamin (MK-7) is a natural vitamin K2 obtained through fermentation.

Being 100% trans ensures high bioavailability and absorption that benefits our bones.

In addition, studies conducted with vitamin MK-7 have shown that this vitamin has anti-inflammatory and cardiovascular properties.

Vitamin K helps keep our bones healthy. If vitamin K intake in the diet is not adequate, the risk of fractures and osteoporosis may increase.


Detailed information

Vitamin K is a fat-soluble vitamin that was originally recognised for its role in the coagulation process (K comes from the German word “Koagulation”). There are two types of vitamin K: vitamin K1 (phylloquinone) and menaquinones (MKs or vitamin K2). Vitamin K 1 is found mainly in leafy green vegetables and vegetable oils, while vitamin K2 is found in products of animal origin and is produced through various bacterial fermentation processes1.

In addition to its role in coagulation (vitamin K is needed for the functioning of many of the enzymes involved in the clotting cascade), vitamin K plays a fundamental role in bone health, as it is required for the activation of osteocalcin, the most abundant non-collagenous protein found in bone2 that helps to fix calcium in the bone matrix, participating in bone mineralisation3. This role in maintaining bone health has been demonstrated in various studies that observed a positive effect of vitamin K on bone mineral density and a reduced risk of fracture4. In countries such as Japan, for example, use of vitamin K2 is approved for the osteoporosis5.

Together with these properties, vitamin K2 promotes suppleness in the arteries by avoiding the accumulation of calcium in the artery walls3, helping to reduce cardiovascular problems.

Although vitamin K is fat-soluble, the body only stores a small amount, so stores of the vitamin can be depleted rapidly if there isn’t a regular supply through diet, while vitamin K deficiency increases the risk of fracture and osteoporosis6. Low levels of vitamin K have also been linked to a greater predisposition to osteoarthritis in the hands and knees7.

Our product: Menaquinone-7 (MK-7)

One dose of our product contains 105 μg (140% NRVs*) of menaquinone-7 (MK-7) (vitamin K2) produced through biotechnology (obtained through natural fermentation). Recently, a study also demonstrated the anti-inflammatory properties of our vitamin MK-78, confirming another mechanism through which vitamin K2 aids cardiovascular health.
