Calcium and heart health -
There is some evidence that calcium supplements can increase the risk of heart attacks. Calcium supplements are usually taken to treat or prevent bone disease, such as osteoporosis.
A review of studies found that calcium supplements increased the risk of heart disease, particularly in healthy, postmenopausal women. But other studies have said calcium supplements don't increase the risk. More research is needed to know how calcium supplements affect a person's overall heart attack risk.
What is known is that calcium from food sources, such as dairy products and leafy green vegetables, isn't a concern. Taking calcium — with vitamin D — does provide a benefit for those who have too little calcium or bone loss. Ask your doctor if a calcium supplement is right for you. There is a problem with information submitted for this request.

Even researchers have a hard time agreeing on the potential effects of calcium on cardiovascular disease. Studies related to calcium and heart disease have shown conflicting results. Sometimes, conflicting results are due to studies using different selection criteria.
That means they might differ in how they study or define heart disease. For example, some studies included patients who self-reported their heart attacks.
Other studies only considered those who got an official diagnosis. To review the most recent research, we looked at new meta-analysis data. A meta-analysis looks at many studies and combines their results to see if there are patterns.
Here are some results from these studies. Researchers acknowledge there are challenges to linking calcium supplements with heart disease or heart attack risk. These include :. This plaque is an early sign of heart disease and increases your risk of heart attack.
Hypocalcemia too little calcium can be dangerous too. You can have all sorts of symptoms that include muscle cramping, seizures, breathing problems, difficulty thinking, and increased risks for congestive heart failure. A balance is definitely necessary.
Calcium is a mineral naturally present in your bones. Ideally, doctors hope that increasing calcium in your daily diet makes you less likely to get fractures bone breaks from osteoporosis.
However, when research about calcium supplements and heart attack risk came about, some doctors were hesitant to recommend calcium supplements. In a word, no. Your body needs calcium to complete a number of functions, including building healthy bones.
Low calcium intakes and levels may also increase your risk of death. The International Osteoporosis Foundation recommends different calcium intakes based on your age.
As you get older, your body is less able to absorb calcium into your bones. This means that you need more calcium as you age. Other foods that have calcium include:. Food manufacturers may also fortify add calcium into other foods, such as bread, cereals, and juice. The test score also may be given as a percentage.
The number is the amount of calcium in the arteries compared to other people of the same age and sex. Your health care team gives you your coronary calcium scan results. The result of a coronary calcium scan shouldn't be used as a single sign of your overall health and risk of heart disease.
The information from the scan should be reviewed with other health information. If a coronary calcium scan shows calcium in the heart arteries, the test is not usually done again.

International Business Collaborations. But do these findings hold weight? A New Zealand team recently published a meta-analysis in the British Medical Journal that raised questions about the safety of calcium supplements. Anna Kalynych, M. This particular meta-analysis found about a 30 percent relative increase in the risk of heart attack in women taking the calcium supplements, but no effect on the number of strokes or on a composite risk factor, called heart attacks, strokes and deaths. In fact, a different meta-analysis, published five months earlier in the Annals of Internal Medicine, looked at data from 17 studies that evaluated three different things: 1 Calcium supplement use alone 2 Vitamin D supplementation use alone 3 A combination of the two This study found that calcium supplements alone had minimal, if any, effect on increasing cardiovascular risk, while vitamin D supplements, at moderate to high dose, appeared to protect against it. So what conclusions should be drawn based on these conflicting accounts? For women who are at high-risk of heart disease, Dr. Kalynych and I both suggest that you not only talk to your physician, but that you try to get as much calcium as you can from your diet. If you are at risk for osteoporosis or are known to have low levels of vitamin D, then you may consider using a vitamin D supplement along with your calcium intake. A new study published online last week in the British Medical Journal re-evaluates the question of whether calcium supplements increase the risk of heart attacks and strokes. Mark Boland and his colleagues from Auckland, Aberdeen, and Dartmouth Medical School had previously published an article looking at the risk women might incur if they took calcium alone without also taking vitamin D. These authors found a slight increased risk of heart attacks in women taking calcium supplements alone. What these authors report is that for those women who were assigned to begin taking calcium and vitamin D as part of the study, there was a modest 13 to 22 percent relative increased risk of cardiovascular problems heart attacks and strokes versus those women who were already taking the supplements before they entered the trial or those women who were given placebo. In fact, those women who were already taking calcium and vitamin D supplements before they entered the trial had no increased risks of heart attacks. While this is confusing, what the authors believe is that those women who did begin taking the calcium supplements in the trial may have had an abrupt change in their blood calcium level that somehow may have been associated with the minimal increased risk of heart attack and stroke. So what should a woman consider out of all this? Close X. |
