The study by the German Cancer Research Centre in Heidelberg involved
nearly 24,000 people aged 35 to 64 whose health was tracked for an
average of 11 years.
Those who used calcium supplements were twice as likely to have a
heart attack as those who didn't use any vitamin/mineral supplements, it
Furthermore, boosting the calcium in one's diet doesn't necessarily

which might raise [heart attack] risk, should be taken with caution,"
said study co-author professor Sabine Rohrmann.
Accompanying the findings, which appear online Thursday in the
journal Heart, is a commentary by two professors from the University of
Auckland who say "the safety of calcium supplements is now coming under
"It is now becoming clear that taking this micronutrient in one or
two daily [doses] is not natural, in that it does not reproduce the same
metabolic effects as calcium in food," said professors Ian Reid and
Supplements are "neither safe nor effective," they concluded, and their use should be discouraged.Read here.
