Vitamin K2 MK-7: K2VITAL®, your ally for bones and calcium

Unlike vitamin K1 (phylloquinone), which is primarily involved in coagulation, K2 MK-7 is distinguished by its role in bone metabolism and calcium distribution. K2VITAL® is a patented form of MK-7, produced by organic synthesis, which guarantees high purity and stability. During pregnancy, vitamin K2 is particularly important for the development of the baby's skeleton and for maintaining the mother's bone density. Its bioavailability and extended half-life make the MK-7 form a reference choice in quality supplements.

Vitamin K2 MK-7 in the diet

Vitamin K2 is found naturally in certain fermented foods, with Japanese nattō being the most concentrated source of MK-7. It is also found in certain aged cheeses such as gouda and brie, in egg yolk, chicken and goose liver, and in pasture butter. Other fermented foods such as sauerkraut and certain yoghurts contain it in more modest amounts. The absorption of K2 is enhanced by the presence of fat in the meal, as it is a fat-soluble vitamin. Dietary intakes of K2 MK-7 are often low in the Western diet, which tends to include few traditional fermented foods. Diets low in fat or animal products may further limit intakes.

Vitamin K2 MK-7 as a supplement

In vitamin during pregnancy, vitamin K2 MK-7 is available as synthetic menaquinone-7 (such as K2VITAL®) or derived from fermentation (nattō). K2VITAL® is a benchmark for purity and stability, certified all-trans — the only biologically active configuration. The pregnancy food supplements Jolly Mama include vitamin K2 to support bone metabolism during maternity. The combination with vitamin D is particularly synergistic, as vitamin D supports calcium absorption whilst K2 directs its deposition towards the bones. This is also important in a menopause food supplement to support the bones.

Check for the all-trans form and the product's traceability. K2VITAL® is of synthetic origin and is suitable for vegetarian diets.
