BioClinic's Vitamin K2 uses menaquinone-7 (MK-7) -- which has the greatest half-life of all the forms of vitamin K with the best extra-hepatic distribution.
Most people are not getting the required intake of vitamin K in their day-to-day diets. Vitamin K is used primarily to support bone metabolism (bone health), vascular calcification, cell growth regulation, ATP production, and blood coagulation.
Clinically, low levels of vitamin K has been associated with stroke, cardiovascular plaque, and diabetes.
