Calcium supplements taken by many older people could be increasing their
risk of a heart attack, research shows.
The study, in the British Medical Journal, said people who took
supplements were 30% more likely to have a heart attack.
Data from 11 trials also suggested the medicines were not very effective
at preventing bone fractures.
Almost 3m people in the UK are thought to have osteoporosis and many take
calcium pills to prevent fractures.
The study recommends doctors review their use of calcium supplements for
managing osteoporosis.
The National Osteoporosis Society said most people should be able to get
enough calcium through their diets, rather than reaching for the medicine
cabinet.
The researchers said those who had a diet naturally high in calcium were
at no increased danger.
'Limited benefit'
In all 12,000 people aged over 40 took part in the trials of calcium
supplements of 500mg or more a day.
<snip>
The risk of heart attack was seen across men and women, was independent
of age and the type of supplement given.
A small increased risk of death was seen in the study but was not
statistically significant, the researchers said.
