vitamin K2 and arterial health
Can Vitamin K2 Reduce Calcification?Vitamin K2 helps activate proteins that manage calcium in the body, particularly matrix Gla-protein (MGP), which inhibits calcium deposition in soft tissues like arteries. Evidence suggests K2 supplementation may slow progression of arterial stiffness and support vascular health, but research does not yet confirm that it reverses established calcification. Most benefits appear with consistent long-term use of the MK-7 form.What the Research SaysObservational studies link higher K2 intake with lower coronary calcification prevalence. Randomized trials show that MK-7 improves vitamin K status markers (lower dp-ucMGP) and may improve arterial stiffness parameters in some populations, especially postmenopausal women. However, trials measuring imaging endpoints have not consistently shown regression of existing calcified plaques. Therefore, K2 is best viewed as a supportive nutrient for vascular wellness rather than a standalone treatment.Practical Supplementation GuidanceFor arterial health, common MK-7 dosages range from 90 to 200 mcg daily, with 180 mcg often used in research. Take K2 with a meal containing fat to enhance absorption. Pair with vitamin D and magnesium for balanced calcium metabolism. Always consult a healthcare professional if you take blood thinners like warfarin or have medical conditions that affect vitamin K absorption.
