Vitamin K2 MK-7: All-trans from Norway
Vitamin K2 exists in different molecular forms, which are labelled MK4 and MK7 according to the length of their side chains. MK7 is currently regarded as the most effective form of vitamin K2, which remains effective in the body for a particularly long time and covers the functional K2 requirement even at low doses.
Vitamin K2 MK7 is also available in various forms, of which only the trans form is biologically effective. The addition ‘all-trans’ refers to an active ingredient that consists of at least 98% vitamin K2 MK7 in the trans form.
Regardless of the manufacturer's claims on the label, extensive labelling fraud is also taking place in this area, as a recent study has shown: Despite being declared as ‘all-trans’ K2, some of the supplements examined in the study contained no vitamin K2 at all and many others contained only 30% trans K2.

Our original K2VITAL® vitamin K2 from Norway is one of the few commercial supplements that consists of at least 99.7% highly effective all-trans MK-7, guaranteed by Norwegian laboratory testing.
MCT Carrier Oil For Optimum Protection And Better Absorption
Vitamin K2 requires fats for optimal absorption. Our Sunday Natural K2 drops therefore feature a premium, coconut-derived MCT oil from the Netherlands as the ideal carrier.
This high-purity MCT oil excels at preserving vitamin K2, minimizing degradation to ensure sustained potency more effectively than many conventional oils. Furthermore, its medium-chain triglycerides (MCTs) provide their own distinct nutritional value.
While capsules and tablets must first break down in the body to release their active compounds, our vitamin K2 in MCT oil form offers immediate bioavailability directly in the mouth for optimal absorption. This oil-based delivery is also exceptionally convenient and ideal for those who have difficulty swallowing pills. All of our oils come with a high-quality glass pipette, ensuring precise, drop-by-drop dosage with ease. Unlike conventional dropper bottles, which can be awkward and prone to smudging, our glass pipettes provide a consistently clean and user-friendly experience.
