The Active Ingredient Is: Vitamin K2 (MK-7)

Vitamin K2 in the MK-7 form is a fat-soluble vitamin that helps activate proteins that regulate calcium use in the body. This MK-7 is produced by natural fermentation of Bacillus subtilis subsp. natto, giving a long-lasting and highly bioavailable source of the vitamin.

In this product, the active ingredient is MK-7, with the emphasis on its role as a nutrient rather than a marketing label. The fermentation-based MK-7 form is noted for stronger bioactivity and prolonged activity compared with other forms of vitamin K.

What Does Vitamin K2 Do?

Vitamin K2 helps with the carboxylation of specific bone proteins, enabling them to bind calcium for bone maintenance. It also supports the carboxylation of proteins related to arterial health, aiding calcium distribution in the body. Dr. Knapen from a university noted that MK-7 can influence bone mineralisation and arterial properties.

This nutrient helps direct calcium to bones and helps preserve arterial flexibility, aligning with EFSA-supported functions for bone and cardiovascular health support.
