Arteries become hardened when calcium accumulates on its wall, thus causing the arteries to lose its flexibility. Extra workload is imposed on the heart as it needs to pump harder to maintain consistent blood flow, resulting in elevated blood pressure which in turn increases the risk of heart disease. Little known to most, Vitamin K, commonly known for its ability to facilitate blood clotting, has shown to be beneficial for heart health. Vitamin K2, or menaquinone, is the form of vitamin K which helps to reduce stiffness in arteries anf thus increases arterial blood flow. It actively regulates the protein that inhibits calcium deposition on arteries. Researchers have found that amount of vitamin K2 in healthy arterial tissues is 100 times more than that in unhealthy arteries! Hence, adequate intake of vitamin K2 is definitely crucial as studies show that increased intake of vitamin K2 may lower the risk of early death caused by cardiovascular disease.
