★ ADVANCED FORMULA!! This supplement adds the power of Vitamin K2 and Magnesium to work synergistically with Vitamin D. Vitamin K2 is very helpful to direct the calcium away from the arteries (where you don't want it) and towards the bones (where you need it). And the Magnesium activates the Vitamin D and increases its absorption in the body. Which means that you get a great boost from a single capsule ★ A POWER PILL! Our supplement contains an optimum high strength combination that is not available in any other brand. The Vitamin K is Natto based MK7 with 150mcg strength (as compared to 100mcg offered by most brands), the vitamin D is 3000 IU cholecalciferol and there's also an additional 20mg Magnesium oxide for the best results.
