Calcium Supplements Risk for Heart Problems

July 20, 2011

If you have been taking these to help your bones, there is a hidden danger that has been exposed by new research in the British Medical Journal which adds to mounting evidence that calcium supplements increase the risk of cardiovascular events, particularly heart attacks, in older women.

Nutritionists have been saying for some time that calcium supplements alone are not a good idea, but these new findings suggest that their use in managing osteoporosis should be re-assessed. They are often prescribed to older (postmenopausal) women to maintain bone health and sometimes they are combined with vitamin D, but there are a whole range of heart supplements that are needed, not just calcium alone.

A team of researchers, led by Professor Ian Reid at the University of Auckland, re-analysed a seven-year trial of over 36,000 women to provide the best current estimate of the effects of calcium supplements, with or without vitamin D, on the risk of cardiovascular events.

What they found was that the women who were not taking personal calcium supplements at the start of the trial but then were given a combined calcium and vitamin D supplement were at an increased risk of cardiovascular events, especially heart attack. By contrast, in women who were taking personal calcium supplements at the start of the trial, combined calcium and vitamin D supplements did not alter their cardiovascular risk.

The authors suspect that the abrupt change in blood calcium levels after taking a supplement causes the adverse effect, rather than it being related to the total amount of calcium consumed. High blood calcium levels are linked to calcification (hardening) of the arteries, which may also help to explain these results. The authors concluded that these data justify a reassessment of the use of calcium supplements in older people.

If you do want to keep your bones strong, and not impact your heart, then gentle regular weight bearing exercise is a start, and add plenty of black pepper to your diet as it contains four anti-osteoporosis compounds and boron, which is also good for bone health, is found in abundance in cabbage. Also healthy for bones are garlic, onions and eggs plus cod liver oil A which is a natural source of vitamins A and D3. If you do want to take a supplement look for one with a good mix of bone building nutrients including vitamin D, calcium, magnesium, silica and boron. Higher Nature make a good one called Osteo Food and the best natural way to build bone is to have good levels of progesterone as that is the first bone-building substance the body needs.
