For what it's worth, since there's divided opinion on taking calcium and whether it builds up in arteries, I've been taking a calcium/vitaminD3/vitaminK2 formula with the usual suspect trace minerals for nearly 7 years now. In an abundance of caution, my cardiologist ordered an Agotsten Calcium Score and echocardiogram and both were excellent. As the cardiologistn is female and also taking a similar supplement, while admitting that science is still looking at calcium supplements and arterial effects if any, she was happy to see no change as I am alas also nearly 7 years older too.
