The meta-analysis included 18 studies published in 1970-2016 (11 from the USA, four from Europe, and three from Japan) with a total of more than 2 million participants from the general population.
This means that the market, especially online, is flooded with "fake" medications and supplements.
According to researchers, the best way to prevent cardiovascular disease is to adopt a healthy diet and consume many different types of fruits and vegetables, which are natural sources of vitamins and minerals.
Dr. Joonseok Kim, a cardiologist and the studys lead researcher, said its time to stop investing time and money in studying the relationship between multivitamins with minerals and heart disease and stroke because theres strong evidence they dont prevent the chronic diseases.
Still, multivitamins remain popular, with up to 30 percent of Americans using the products; and some people reportedly using them to prevent heart disease, the researchers said.
A new study has shown that intake of multivitamins and supplements would not in any way shield you from heart attacks, or any cardiovascular death. Neither group advises using these multivitamin and mineral supplements to prevent cardiovascular disease. Fruits and vegetables already have a proven track record in lowering the risk of heart disease and stroke.
For now, Kim said the best he can hope for is that the findings resonate with the Americans who spend an estimated $5.7 billion a year on multivitamins because they mistakenly think theyre improving their health.
This, despite the fact that prior studies have "consistently demonstrated no benefit" from supplements when it comes to heart health, Fonarow said. Food and Drug Administration for either safety or effectiveness - affect heart health.
Use of MVM supplements was not associated with the risk of death from cardiovascular disease or coronary heart disease, or stroke incidence or deaths, according to the report in Circulation: Cardiovascular Quality and Outcomes.
"The evidence-based, guideline-recommended approaches to reduce the risk of fatal and non-fatal cardiovascular disease include maintaining a healthy blood pressure, cholesterol levels, body weight, not smoking, and engaging in daily physical activity", Fonarow added. But, for a healthy adult with no specific diagnosed deficiency, this research affirms that taking vitamin supplements unnecessarily will only result in expensive urine.
It's important to note that this research doesn't suggest that vitamin or mineral supplements are useless in clinical cases where a patient actively needs those supplements.
