ArtriFlo-K is a synergistic 2-in-1 formula that combines Vitamin D3 with special MenaQ7 Vitamin-K2 – the patented Vitamin K2 (as MK-7) from *NattoPharma ASA, Norway. Vitamin K2 is important for healthy vascular blood flow in our bodies as it prevents accumulation of Calcium deposits from hardening in our blood vessels by ensuring Calcium is properly absorbed into the bones. When not properly absorbed into our bones, Calcium can end up in our blood vessels and harden; thereby restricting and impeding circulation and vascular blood flow in our bodies. Take 2 capsules of ArtriFlo-K daily to stay healthy and young at heart. ?*NattoPharma ASA (Norway) is the world leader in Vitamin K2 research for bone and heart health and the exclusive innovator of MenaQ7 Vitamin K2 (as MK-7) with guaranteed actives and stability, clinical substantiation and international patents granted and pending.
