Calcium: Healthy Bones . . . Sick Heart?

Calcium is making its way into numerous food products, like orange juice (up to 500 mg per 8 oz serving) and bread. Many people take calcium supplements. If you have made the effort to normalize the vitamin D levels in your system, are you increasing your risk for heart attack?

My personal view is that, given our new appreciation for the impact of vitamin D on calcium absorption, we should reduce our calcium intake to no more than 600 mg per day. Of course, this requires confirmation in a new round of studies examining people who take "modern" doses of vitamin D of 2000, 4000, 8000, or more units to restore blood levels to normal.
