Pure Nutrition Vitamin D3 with Vitamin K2 provides the right amount of each essential vitamin to maximize their benefits to support brain and heart health. Vitamin D (specifically d3) is essential for absorbing the calcium. While vitamin D ensures that calcium is absorbed, vitamin k2 (specifically as mk-7, the most bioavailable form) is purported to direct the calcium into the bones and out of the bloodstream and arteries, which helps promote both bone mineral density and arterial flexibility.
