September 2011/NutraSolutions -- Vitamin K was discovered in 1929, and it was deemed essential, due to its ability to prevent a decrease in prothrombin, a coagulation factor necessary for normal clotting of blood. Over the past decade, vitamin K has also been linked to bone health and cardiovascular health.
Natural vitamin K2, as menaquinone-7 (MK-7), is the most bioavailable, longest-lasting and most bioactive form of vitamin K. Research by P.L. Thomas & Co. on its proprietary MK-7 MenaquinGold™ is extending the scientific base for vitamin K, through assessments of alleviating muscle cramping and improving aerobic capacity.
