PureHeart K2D - *Maintains healthy vascular calcium homeostasis to support cardiovascular function

What Is It?

Vitamin K includes a group of compounds that contain a central ring structure with varying side chains. These differing side chains account for differences in absorption, bioavailability, transport and tissue distribution. Vitamin K 1 , phylloquinone, is the most common form and is found in plants and green vegetables. Vitamin K 2 (MK-7) is less common and found primarily in fermented soy. Studies indicate that while vitamin K 1 is primarily concentrated in the liver, vitamin K 2 (MK-7) is concentrated in extra-hepatic tissues, including vascular tissues, allowing for targeted support. MK-7 also has a longer half-life.*

Uses For PureHeart™ K 2 D

Vascular Health: Vitamin K 2 menaquinone-7 (MK-7) promotes healthy vascular calcium homeostasis and cardiovascular function. In a systematic review involving 5 studies, higher intakes of vitamin K 2 were 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 K 1 , which concentrates in bone, MK-7 concentrates in vascular tissue where it supports healthy arterial blood flow and vascular elasticity. In an observational study involving 564 postmenopausal women, higher intake of vitamin K 2 was associated with healthy 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.*

What Is The Source?

Vitamin K 2 (MK-7) is naturally derived from flower extracts geraniol and farnesol. Vitamin D 3 is derived from lanolin. Hypo-allergenic plant fiber is derived from pine cellulose.
