NuMedica Micellized D3 + K2™ is a soy-free, natural vitamin D3 and vitamin K2 in a water-soluble micellized form. Micellization greatly increases the solubility, absorption and bioavailability over oil or emulsified forms. This formula includes the patented VitaMK7®, a natural vitamin K2 (as MK7) which supports enhanced utilization of calcium in the bloodstream. It is an all-trans natural menaquinone-7 with the highest bioavailability and longest half-life in the blood. VitaMK7® is shown in human clinical studies to increase osteocalcin (calcium-binding protein) levels, enhancing the body’s ability to utilize calcium in the bloodstream. It is also shown to prevent bone loss and promote bone integrity while significantly reducing the incidence of arterial calcification, promoting optimal cardiovascular function.
