Calcium supplements & heart attacks.

Dr Ian R Reid has reported on a meta-analysis study, in the British Medical Journal, that found that calcium supplements are associated with a 30% greater risk of heart attacks.

The team looked at 11 studies where calcium supplements were tested without vitamin D. These studies mainly investigated calcium supplements in osteoporosis treatment. None of the studies specifically investigated calcium supplements v heart attacks.

Dr Reid was interested because – calcium supplements give only a small benefit in osteoporosis treatment yet are widely used – dietary calcium appears to protect the cardiovascular system – yet calcium supplements appear to make the cardiovascular system worse – according to other studies.

So he pooled results from 11 studies covering nearly 12,000 people, looking only at those where vitamin D was not used, as vitamin D has been shown to have a protective effect on the heart.

Dr Reid and colleagues concluded “Calcium supplements (without coadministered vitamin D) are associated with an increased risk of myocardial infarction. As calcium supplements are widely used these modest increases in risk of cardiovascular disease might translate into a large burden of disease in the population. A reassessment of the role of calcium supplements in the management of osteoporosis is warranted.”
