Vitamin D3 (cholecalciferol) and Vitamin K2-7 (menaquinone) work synergistically to help maintain bone health.* Vitamin D3 helps maintain healthy serum calcium levels by promoting intestinal absorption and reducing urinary excretion of calcium. Vitamin K2-7 supports healthy bone mineralization by acting as a cofactor in the carboxylation of osteocalcin, allowing calcium to bind to this protein in the extracellular matrix of bone.* Vitamin K2-7 also supports healthy cardiac and vascular function.* This form of Vitamin K concentrates in the tissues of the arteries, where it aids in carboxylation of Matrix Gla Protein to help maintain normal calcium metabolism and support healthy vascular elasticity.* Additionally vitamin K2 may help support healthy lipid levels and glucose metabolism.* Although frank vitamin K deficiency is rare, research suggests the Western diet may not contain sufficient Vita-min K2-7 to optimize carboxylation of Gla outside the liver.* Higher dietary intakes of K2 have been associated with healthy levels of arterial calcification and elasticity.* Compared to other forms of Vitamin K, Vitamin K2-7 has a longer half-life, resulting in more stable levels in the body.* For best absorption of these fat soluble vitamins, take with a mixed meal or some healthy dietary fat.*
