Most Supplements Offer Little Protection Against Heart Disease

"Except to prevent or specific deficiencies" similar to low vitamin D levels, or in specific circumstances similar to being pregnant, "there's usually a good agreement that dietary supplements shouldn't be recommended to the general population."The new analysis, which involved nearly one million sufferers overall, additionally discovered limited proof that a low-salt diet might reduce the danger of death, however, in an editorial following the review, specialists known as that a "peculiar and controversial finding". Omega-3 long-chain polyunsaturated fatty acid correlated with a reduced risk for myocardial infarction and coronary heart disease based on low-certainty evidence (RRs, 0.92 and 0.93, respectively).

Supplements combining calcium and vitamin D appeared to increase the risk of having a stroke by 17 per cent.

However, scientists have urged caution in interpreting the results as establishing cause and effect is the field of nutrition is notoriously hard.

Researchers from West Virginia University analysed 277 randomised controlled trials of close to one million people to determine the effects of 16 nutritional supplements and eight dietary interventions when it came to reducing the risk of cardiovascular disease in adults.

Other supplements namely selenium, vitamin B6, vitamin E, vitamin C, iron, and vitamin A, among others, show no significant effect on heart health.

Doctors often recommend certain dietary interventions - such as following a Mediterranean-type diet or cutting salt intake - in the interest of protecting heart health.

There are no data to support the common use of supplements and vitamins, and it follows that testing for levels of vitamin D or other vitamins has little basis, Topol, founder and director of the Scripps Research Translational Institute, told LabPulse.com by email. Reduced salt intake seems to lower blood pressure, according to a 2013 review, and "the science behind sodium reduction is clear", according to the American Heart Association. Other research has associated calcium supplements with an increased risk of MI and death from cancer.

Khan says that these findings contradict the PREDIMED trial published in The New England Journal of Medicine, which found that the incidence of cardiovascular disease in the Mediterranean diet groups was lowered by approximately 30 percent when compared with the control diet. "Different reviews reach different conclusions", she said. Different supplements like the mix of Vitamin D and calcium tablets, were found to expand the rate of heart diseases. Vegetarian diets have also been tied to a lower risk of heart disease. In addition, following these dietary interventions didn't show any beneficial effects.

More complex research is needed, Lee said, but his advice, for now, is simple: Watch how much salt you consume and eat a range of natural foods, not supplements, to get the nourishment you need.
