Stop Taking Multivitamins to Help Your Heart. Researchers Say They Don't Work

Multivitamins are popular, with 30 percent of Americans using various products, with a number of them using the tablets specifically to prevent heart disease.

A new study confirms that taking multivitamins can not reduce the risk of heart attack, stroke, and death from cardiovascular disease.

"We hope that our paper helps to settle the debate" on the use of multivitamins and minerals (MVM) for cardiovascular disease prevention.

"It has been exceptionally hard to convince people, including nutritional researchers, to acknowledge that multivitamin and mineral supplements don't prevent cardiovascular diseases", Kim said.

In a new study published in an American Heart Association journal on July 10, researchers discovered no link between taking multivitamins and a lower risk of heart attacks, strokes, and death related to cardiovascular disease.

For the study, the research team conducted a "meta-analysis"- which involved putting together the results of 18 previously published studies- including several randomized controlled trials and potential cohort studies.

The finding is in line with guidelines from the American Heart Association, which does not recommend the use of multivitamins to prevent cardiovascular diseases. "It may be unlikely for a supplement ingested once a day to confer a health benefit". Neither group advises using these multivitamin and mineral supplements to prevent cardiovascular disease.


The relationship between dietary supplements and cardiovascular disease has been debated for many years, despite the findings of many studies that there is no association.

"I would like to encourage people to discuss the use of MVM supplements with their physicians and reallocate their resources to something that is proven to improve cardiovascular outcomes, such as fruit and vegetable intake and exercise".

"Americans who are taking these supplements presumably because they're concerned about their health would be better served spending their money on good nutrition in the form of a healthy diet", Dr. Erin Michos, a cardiologist at John Hopkins University, said.

How? According to Kim, placing one's faith in supplements "could deviate the public from following measures that are proven to be beneficial for cardiovascular health".

"CRN stresses that multivitamins fill nutrient gaps in our less-than-perfect diets and support a host of other physiological functions", senior vice president Duffy MacKay said in a statement. He noted that upwards of 100 million American men and women take vitamins or supplements "frequently based on the misguided belief that doing so can improve their heart and vascular health".
