Multivitamins are often marketed as a shortcut to better health. But the evidence questioning their so-called benefits is stirring, the latest research indicating that they are doing nothing to protect our hearts.
Following an analysis of 18 existing studies, the researchers concluded that taking multivitamins and minerals did not bring any benefit to preventing heart attacks, strokes or deaths caused by cardiovascular diseases
. three vitamin and mineral ingredients. Earlier this year, researchers in Canada behind a separate study similarly conclude that common supplements like vitamin D, calcium, and vitamin C do not protect against cardiovascular disease or premature death. This follows a 2013 article titled "Enough, it's enough: stop wasting money on vitamin and mineral supplements," in which the researchers warned that the pills did not show any advantage and could even harm. These studies question the existence of the $ 1 billion vitamin industry, which is expected to reach $ 278 billion by 2024.
Joonseok Kim, assistant professor of Cardiology at the Department of Medicine at the University of Alabama in Birmingham, said: "We have found no clinical benefit from the use of multivitamins and minerals to prevent heart attacks, stroke or cardiovascular death. "

They published their findings in the journal Circulation: Cardiovascular Quality and Outcomes which is published by the American Heart Association.
Kim commented that despite growing scientific evidence, it has been "exceptionally difficult" to spread the message that multivitamins and minerals do not prevent heart disease. even among nutritional experts. She explained that even though the study indicated that multivitamins and mineral supplements taken in moderation did not appear to be harming cardiovascular health, working with a health care provider to create a plan to reduce heart risks is much more efficient.
"I hope our results will help reduce the hype around multivitamin and mineral supplements and encourage people to use proven methods to reduce their risk of cardiovascular disease, such as eating more fruits and vegetables, making exercise and avoid smoking ".
At present, manufacturers of mineral supplements and vitamins have no legal impediment to cross before selling them to the general public, and at least 30% of the US population take multivitamins and mineral supplements. Dr. Eduardo Sanchez, Chief Medical Officer of the American Heart Association for Prevention and Chief of the Association's Assessment and Health Centers, who was not part of this study, commented : "Eat a healthy diet for a healthy heart
" Nothing can replace a balanced and nutritious diet with more fruits and vegetables that limit excess calories, saturated fats, trans fats, sodium, sugar and dietary cholesterol. "

Commenting on the Canadian study published in the Journal of the American College of Cardiology Aisling Pigott, a Registered Dietitian and Spokesperson of the British Dietetic Association says Newsweek he has provided further evidence that "there is no" pill "instead of a good diet."
"If you have a healthy and balanced diet, you do not need vitamin and mineral supplements," she commented at the time. "However, recent recommendations suggest that we could all consider vitamin D supplementation, especially during the winter months," she said, when sunlight is scarce because vitamin is synthesized in the body by exposure to the sun.
