Product OverviewVitamin K2, scientifically known as menaquinone, is a fat-soluble nutrient essential for activating proteins that regulate calcium metabolism, directing it to bones rather than blood vessels. It significantly supports cardiovascular health by preventing vascular calcification and enhances bone density. Key sources include fermented foods (natto) and animal products, particularly in MK-4 and MK-7 forms. Forms of Vitamin K2The"MK"stands formenaquinone, and the number refers to the length of its side chain. The two most important forms for human health are:
MK-4:Found in animal products (egg yolks, butter, liver, dark chicken meat). It has a short half-life (hours), so it needs to be consumed regularly.
MK-7:Derived from bacterial fermentation. Found in natto (a Japanese fermented soybean dish, which is the richest source), aged cheeses (like Gouda), and sauerkraut. It has a much longer half-life (days), leading to more stable and sustained blood levels, making it the preferred form for supplements.
