K2VITAL is the purest, most
active and safe vitamin K2 MK-7, with proven bioavailability
Allergens are a serious concern and may impact labelling. Products produced by fermentation mostly use a soy-based raw material. This may require soy to be listed as an allergen. K2VITAL® is free from all known allergens.
Further, it does not contain residual solvents, metals or microbial contaminants.
Published Safety Data
Consumer safety is our utmost concern. It is with that in mind, K2VITAL® underwent a stringent safety assessment. K2VITAL® is the only Vitamin K2 MK-7 with published safety data, ensuring peace of mind for manufacturers and consumers alike.
Acute and sub-chronic toxicity studies of synthetic K2VITAL® were conducted according to OECD guidelines for testing of chemicals:
Acute toxicity in mice:
Dose tested: 2g/kg
(e.g. 2million X recommended dose)No adverse effects*
Sub-chronic, 3 months in rats:
Dose tested: 0; 2.5, 5; and 10 mg/kg/day for 90 days
(e.g. 10 000 X recommended dose)No treatment related effects*
The no-observed-adverse-effect level, NOAEL = 10 mg/kg/day (based on the highest dose tested)
