Vitamin K2 100µg – 90 capsules

Vitamin K2: menaquinone MK-7 ensures high bioavailability

This product contains vitamin K2 in its natural form menaquinone MK-7. It´s an extract from non-GMO soybeans, which were fermented with Bacillus subtilus natto. MK-7 is an improved bioactive form of vitamin K2 from Natto, which can be absorbed excellently.

Natural vitamin K2

Vitamin K is one of the fat-soluble vitamins and belongs to the group of phylloquinones. In nature, there are two forms of vitamin K: Phylloquinone (vitamin K1) which is synthesised by plants and menaquinone (vitamin K2) which is derived from fermentation.

Vitamin K2 in food

Vitamin K2 can primarily be found in fermented and animal-based foods, which include, for example, offal, meat, egg yolk, dairy products, certain cheeses, yogurt and sauerkraut.
This is why vegetarians and vegans in particular should ensure an adequate supply and, if necessary, resort to vitamin K2 capsules.

Who is affected by vitamin K2 deficiency?

Normally, a balanced nutrition ensures an adequate supply of vitamin K2 to meet the body’s requirement. However, there are certain conditions, for which a supplementation may be reasonable. For example, absorption disorders, intravenous nutrition, a vegan or vegetarian diet. An extreme low-fat diet can lead to malabsorption of the fat-soluble menaquinone.

Vitamin K2 and blood coagulation

Vitamin K2 involved in the formation of different coagulation factors in the liver. The main task of vitamin K is the synthesis of certain proteins, which play an important role in the blood coagulation.

Vitamin K2 and bones

Vitamin K2 is directly involved in the bone formation within the calcium metabolism by activating endogenous proteins such as osteocalcin and MGP.
Menaquinone MK-7 ensures that the calcium remains in the bones and does not deposit in the blood vessels, joints and tissues.

A study about vitamin K2

Results of a Dutch study published in 2015 by the University of Maastricht confirm that menaquinone MK-7 vitamin K2 is not only able to reduce the age-related arterial stiffness, but also improves the vascular elasticity significantly.
Additionally, the supplementation of vitamin K2 had a positive effect on the blood level of a protein, which plays a main role in counteracting vascular calcification.
