Added K2 to my regimen a while back when I learned it and vitamin D are needed together for calcium absorption. Too much D w/o K2 appears to make bones more brittle. As mentioned above, it's not abundant in the western diet. I wonder if places where there is more K2 in the diet have less osteoporosis?
