Why is it now being said not to take calcium supplements?

Increase heart risk. Some very large studies have recently found increased risk of heart attack in men & women & increased risk of death from heart disease in men taking calcium suups. It is thought that calcium supps can increase calcium deposits in the arteries. However, calcium helps with osteoporosis & taking vit k with calcium should prevent this problem.
