For those of your taking Calcium, Magnesium and DS-3, please add Vitamin K2 (MK7form) to your list of supplements. "For Healthy Bones. Research has shown that Vitamin K2 is one of the most important nutrients for long-term bone health and that it is even more important than calcium. K2 is needed to help calcium and other minerals bind into the bone matrix to strengthen bones (and not to stay in soft tissue where it can cause calcification in the wrong places). In fact, studies have shown that Vitamin K is effective at not just stopping bone loss in people with osteoporosis but potentially reversing it as well."
