Vitamin K2 is one of our channel subscribers’ favorite topics. We also get a lot of questions about blood thinners and vitamin K2. For instance, here’s a question posted by a viewer on our YouTube channel. Does vitamin K thin your blood? No. In fact, vitamin K makes blood thicken or “coagulate” to form a clot. If you’re wounded or get a cut, it is this clotting process that would stop the flow of blood. However, vitamin K can interfere with a specific class of blood thinners called VKA (vitamin K antagonist). What are vitamin K antagonists? A vitamin K antagonist (VKA) is a special blood thinner. VKAs prevent blood clots by decreasing the action of vitamin K. Among VKAs, coumarins are the most commonly used. And among coumarins, warfarin (sold under the brand name Coumadin and Jantoven) is the most popular. The interfering action, however, goes both ways. VKA depletes the action of vitamin K. On the other hand, vitamin K also interferes with the blood-thinning action of VKAs (InnovixLabs, 2019). What are blood thinners? Blood thinners are medications or supplements that help blood flow smoothly. They don’t thin your blood or break up clots. They just decrease the risk of clots by slowing the clotting mechanism. There are 2 types of blood thinners: anticoagulants and antiplatelets (WebMD, 2020). Anticoagulants keep your blood from clotting. Examples of anticoagulants are: Apixaban (Eliquis) Rivaroxaban (Xarelto) Dabigatran (Pradaxa) Heparin (Fragmin, Innohep, Lovenox) Warfarin (Coumadin, Jantoven) Antiplatelets target tiny particles in the blood
