No link between calcium supplements and artery plaque
People take calcium to maintain bone health but some are concerned too much calcium could raise chances for arterial plaque and heart disease, especially in type 2 diabetes.

In this study, doctors looked at the effect of calcium in the diet and from supplements on arterial calcification in 720 people with type 2 diabetes. The researchers measured calcification in the coronary and carotid arteries, in the abdominal aorta, and also considered longevity.

They found no link between calcium in the diet or from supplements and arterial plaque, and also no greater chances of dying from any cause. In fact, women who got calcium from diet and supplements were more likely to survive.
