D3 + K2 is a soy-free, natural vitamin D3 and vitamin K2 formula. Vitamin D, considered both a hormone and a vitamin, is manufactured in response to skin’s exposure to sunlight and is essential to the body’s absorption of calcium. Natural vitamin D3 (cholecalciferol) is four times more potent than synthetic vitamin D2.* In Latin, calciferol means “calcium carrier.” Strong evidence suggests that vitamin D intakes well above current recommendations are beneficial, and when combined with calcium, have a significant impact on overall bone health.* Additionally, vitamin D has been the subject of numerous studies for its effect on the immune system by promoting phagocytosis and immunomodulatory functions.*

This formula includes a natural vitamin K2 (as menaquinone 7) 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.* Menaquinone 7 supports prevention of bone loss and promotes bone integrity while significantly reducing the incidence of arterial calcification, promoting optimal cardiovascular function.
