Research consistently shows that while Vitamin K is crucial for normal blood coagulation, Vitamin K2 does not lead to excessive clotting or increased blood thickness. Today, we are addressing the widespread myth that Vitamin K2 can cause elevated coagulation levels.
Vitamin K is vital for maintaining proper blood coagulation, a natural and healthy process that prevents excessive bleeding. This raises a common question: Does Vitamin K increase blood thickness or elevate the risk of thrombosis?
Do you know Vitamin K?
Vitamin K, historically viewed as a single nutrient, is a group of fat-soluble vitamins essential for human health. The two key forms are Vitamin K1, primarily found in leafy greens, and Vitamin K2, present in small amounts in fermented foods.
Vitamin K1 plays a primary role in supporting blood clotting by activating clotting factors in the liver. In contrast, Vitamin K2 has additional health benefits, including supporting bone strength and cardiovascular health. Unlike K1, Vitamin K2 stays in the bloodstream longer, making it more bioavailable for various tissues.
Vitamin K2 and Blood Coagulation
Prothrombin, a protein activated by Vitamin K, is central to the blood coagulation process. It influences clotting when necessary but does not determine blood thickness. Vitamin K ensures that clotting factors function optimally, preventing harmful bleeding. A deficiency in Vitamin K, however, leads to impaired coagulation, resulting in prolonged bleeding.
While Vitamin K2 activates clotting proteins like K1, it does not increase the risk of thrombosis in healthy individuals. The liver primarily uses Vitamin K1 for coagulation processes, leaving K2 available for other functions, such as maintaining cardiovascular health.
Coumarin: The Only Concern with Vitamin K2
Patients on vitamin K antagonists like warfarin should consult a healthcare provider before supplementing with Vitamin K2. Warfarin and similar drugs inhibit Vitamin K, which can affect bone and cardiovascular health over time. Fortunately, new anticoagulant drugs, such as direct oral anticoagulants (DOACs) and anti-platelet medications like aspirin, do not interfere with Vitamin K2, allowing for safe supplementation.
MenaQ7®: Proven Safe and Effective
Clinical research on MenaQ7® Vitamin K2 has demonstrated no increase in blood clotting risk or coagulation levels. Studies across children, adults, and patients with kidney issues confirm stable thrombin and coagulation parameters, reinforcing the safety and efficacy of Vitamin K2 for supporting bone and cardiovascular health.
With advancements in antithrombotic medications, patients can safely integrate MenaQ7® Vitamin K2 into their routines to promote healthy aging and development while maintaining robust cardiovascular and bone health.
