Are multivitamins worthless?
People who take multivitamins to protect their heart health are wasting their money, new research has found. A review of 18 studies involving 2 million people followed for an average of roughly 12 years found no scientific evidence that these products help prevent heart attacks, strokes, or death from heart disease regardless of people’s age, gender, and level of physical activity. These findings echo guidelines from the American Heart Association, which discourages the use of multivitamins for the prevention of heart disease. Nevertheless, dietary supplement sales are on the rise, and nearly 30 percent of Americans take multivitamins on a daily basis, assuming they’ll be healthier for it. Some people even hope vitamins can make up for a poor diet or lack of exercise. “I hope our study findings help decrease the hype around multivitamin and mineral supplements,” the study’s lead author, Dr. Joonseok Kim, tells NBCNews.com. The researchers say you can promote heart health by eating a healthy diet rich in fresh fruits and vegetables, exercising regularly, and not smoking. ■
