Apparently Calcium supplements are bad for you too

I was rather surprised to find out that the popular calcium supplements aren't good either. http://www.jonbarron.org/heart-health-program/nl100809/killer-calcium.php

The article is saying:

"A little over two years ago, Dr. Ian Reid conducted research that unexpectedly showed a slight increase in heart attacks among healthy, older women who took calcium supplements to prevent fractures. This was surprising since, as Dr. Reid said, "Our hypothesis when we started the study was that calcium would protect the heart."

Stirred by this quirk in the data, Dr. Reid and his colleagues performed a meta-analysis of the existing data by combining and analyzing the findings from 11 randomized trials in which some 12,000 participants took calcium supplements (500 milligrams or more per day) without vitamin D. After adjusting for differences in study design, the researchers concluded that calcium supplementation was associated with a 20-30 percent increase in the risk for heart attacks."

If you do take multi-mineral supplements, than take additional magnesium to even out the calcium. Most supplements have more calcium than magnesium in them, which is completely backwards.
