What does it mean? Why do brands prefer it, and how is it different from MK-4? This article explains <strong>vitamin K2 MK-7<\/strong> in 6 short points.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_What_Is_MK-7\"><\/span>1. What Is MK-7?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Vitamin K is not a single compound but a family that includes K1 (phylloquinone) and K2 (menaquinones). Menaquinones are named by the length of their side chain, from MK-4 up to MK-13. MK-7, or menaquinone-7, has 7 units in that chain.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Why_Do_Supplements_Prefer_It\"><\/span>2. Why Do Supplements Prefer It?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The key advantage is that vitamin K2 MK-7 stays in the blood for a long time \u2013 around 3 days \u2013 compared with just a few hours for MK-4. A small dose once a day is therefore enough to keep a steady blood level, which is why it is the most common form in supplements.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_MK-7_vs_MK-4_vs_K1\"><\/span>3.

What Does It Do in the Body?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Vitamin K2 activates osteocalcin, which binds calcium into bone, and matrix Gla protein (MGP), which helps prevent calcium from building up in blood vessels. In a 3-year study of postmenopausal women, 180 mcg of MK-7 a day helped slow the loss of bone density. The evidence is still developing, though, and it does not replace osteoporosis treatment prescribed by your doctor.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5_Common_Doses\"><\/span>5.
