Calcium Supplements Are . . . Safe?

by Berkeley Wellness  

If you take calcium supplements and are concerned about their safety, here’s good news:

A Harvard study of 75,000 female nurses has linked the supplements to a reduced risk of heart attacks. In recent years several studies suggested that calcium pills increase the risk of coronary artery disease, which has caused some people to stop taking them. This potential risk has been much debated, however, and many other studies have not supported it.

The new observational study, in Osteoporosis International, found that women who took 1,000 milligrams or more of calcium a day had a 29 percent lower risk of heart attack over a 24-year period than nonusers; age, weight, dietary calcium, vitamin D, and various cardiovascular risk factors were controlled for.
