Menaquinone-7
Based on 3 publication(s) in Google Scholar
Menaquinone-7 (Vitamin K2-7), belongs to a class of K2-vitamin homologs (orally active), is originally discovered as the anti-hemorrhagic factors. Menaquinone-7 inhibits osteoclast bone resorption in vitro and stimulates bone formation in femoral tissue of aged female rats. Menaquinone-7 has a well-researched potential in the prevention of aging-induced bone degeneration. Menaquinone-7 is also a pharmacological option for activating Gla matrix protein and intervening in the progression of calcific aortic stenosis (CAVS).
