PureHeart^® K₂D helps maintain healthy calcium balance in vascular tissue for optimal cardiovascular function. PureHeart^® K₂D targets vascular tissue to support healthy arterial blood flow and vascular elasticity.^‡

^{Vitamin K₂ menaquinone-7 promotes healthy vascular calcium balance and cardiovascular function. In a systematic review involving 5 studies, higher intakes of vitamin K₂were associated with cardiovascular health. Research indicates that it supports the carboxylation of matrix Gla-protein (MGP), a key protein involved in calcium balance. Unlike vitamin K₁, which promotes bone health, 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, in part by supporting the activity of MGP. Studies indicate that the combination of vitamin K and D provides synergistic support. Vitamin K supplementation may be contraindicated for those taking Coumadin/warfarin anticoagulant medication.‡}
