Some supplements help your health, others do not

The remaining 13 supplements studied showed no benefit or harm.

The brand new research, which included nearly a million patients overall, additionally discovered limited proof that a low-salt diet might cut back the chance of death, but in an editorial accompanying the review, specialists referred to as that a "peculiar and controversial finding".

Researchers from West Virginia University analyzed 277 randomized controlled trials comprising almost a million people to determine the effects of 16 different nutritional supplements and eight dietary interventions on mortality and cardiovascular outcomes in adults. 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). They found that most vitamins, minerals, supplements, and diets examined had no protective effects against cardiovascular health.

Still, the authors conclude that there's enough evidence to suggest that people shouldn't start taking supplements just because they want to prevent heart problems.

Supplement use is on the rise in the US, where almost 3 in 4 people take at least one such product, according to the report.

At the same time, however, other supplements and interventions seemed to either have no effect or be downright harmful.

In fact, people who took calcium and vitamin D supplements together actually had a higher risk of experiencing a stroke, although only with moderate certainty.

Supplements that did not appear to have any significant effect on mortality or cardiovascular outcomes included selenium, vitamin A, vitamin B6, vitamin C, vitamin E, vitamin D alone, calcium alone, folic acid, and iron.

"Calcium plus vitamin D can increase calcium content in the blood and increase calcium deposition in blood vessels", says Khan. They also noted that following a Mediterranean diet, reducing saturated fat intake, modifying fat intake, reducing dietary fat intake, and increasing the quantity of dietary omega-3 and omega-6 were not beneficial. People with hypertension are already at risk for various cardiovascular events.

Reduced salt intake was associated with improving overall survival and cardiovascular mortality.

The findings had been unsurprising, mentioned Susan Jebb, a professor of diet and inhabitants health at the University of Oxford.

That method may not be the best way to study diet and heart disease, according to Lee. All these works were aimed at identifying the relationship between taking dietary supplements and reducing the risk of premature death, as well as the development of cardiovascular diseases.

The scientists found that solitary a bunch of the dietary supplements alongside only one of the eight dietary intercessions had some defensive advantages against heart diseases. Doctors often recommend interventions on diet to protect heart health.
