Vitamin K
Vitamin K is the quiet player in the background. It contributes to normal blood clotting and to the maintenance of normal bones. In calcium metabolism it forms a pair with vitamin D3, its most common companion. A solid foundation, here and now.
In this category you will find vitamin K2 in the premium menaquinone MK-7 form, on its own or in proven D3 + K2 combinations. All with clean formulas free of unnecessary additives.

Good to know
- K1 vs. K2 – K1 comes mainly from leafy greens, K2 (menaquinones) from fermented foods. In supplements, the long-acting MK-7 form has become the standard.
- A pair with D3 – vitamin D3 supports calcium absorption while K2 contributes to the maintenance of normal bones, which is why they belong together.
- Fat solubility – take with a meal containing fat.
