In a systematic review involving five studies, higher intakes of vitamin K2 were associated with cardiovascular health. Research indicates that it supports a key protein involved in calcium balance. Unlike vitamin K1, which promotes bone health, vitamin K2 (as menaquinone-7) targets vascular tissue to support healthy arterial blood flow and vascular elasticity. In an observational study involving 564 postmenopausal women, higher intake of vitamin K2 was associated with calcium balance in the vascular tissue. Optimal serum levels of vitamin D are also important to maintain healthy calcium balance in vascular tissues. Studies show that the combination of vitamin K and D provides synergistic support.‡
