20 Feb 2015 --- A new study has shown the positive impact of MenaQ7 Vitamin K2 as MK 7 (menaquinone 7) on cardiovascular health through its improvement of arterial flexibility. The study titled “Menaquinone 7 Supplementation Improves Arterial Stiffness in Healthy Postmenopausal Women” is significant because it confirms what previous population-based studies have only been able to show an association, according to Cees Vermeer, renowned vitamin K2 scientist and Chief Innovation Officer at the R&D Group VitaK of the Maastricht University Holding (the Netherlands), who led the study’s research team.
