The finding is in line with guidelines from the American Heart Association, which does not recommend the use of multivitamins to prevent cardiovascular diseases. Scientists found out that there was no correlation between consuming multivitamin and mineral supplements and low risk of demise from cardiovascular disorders.
This means that the market, especially online, is flooded with "fake" medications and supplements.
Controversy about the effectiveness of multivitamin and mineral supplements to prevent cardiovascular diseases has been going on for years, despite numerous well-conducted research studies suggesting they don't help. The lower incidence of coronary heart disease among users of multivitamin and mineral supplements in the European and Japanese studies may, therefore, have been due to their diet rather than to the supplements. But the popular supplements dont prevent heart disease or stroke, a new study shows.
And despite strong evidence that eating five to 10 servings of fruits and vegetables a day reduces the risk of cancer, heart disease, Alzheimer's and a range of other diseases, just 13 percent of Americans meet this goal, the CDC found.
"If one does not have a confirmed vitamin deficiency, there is no role for vitamin/mineral supplements in cardiovascular disease prevention", he said.
Many consumers take multivitamins or supplements as a quick and easy way to improve their health.
Kim commented that despite the growing scientific evidence, it has so far been "exceptionally difficult" to spread the message that multivitamins and minerals don't prevent heart disease-even among nutritional experts.
The lack of benefit was observed across subgroups and adjusted analyses, Joonseok Kim, MD, of the University of Alabama at Birmingham, and colleagues reported in the July issue of Circulation: Cardiovascular Quality and Outcomes.
"If you have a healthy balanced diet, you do not need to take vitamin and mineral supplements", she commented at the time.
It is "logical" to expect certain vitamins to reduce cardiovascular events, given their anti-inflammatory effects, Alyson Haslam, PhD, and Vinay Prasad, MD, MPH, both of Oregon Health & Science University in Portland, noted in an accompanying editorial. "These include a heart-healthy diet, exercise, tobacco cessation, controlling blood pressure and unhealthy cholesterol levels, and when needed, medical treatment", Kim said.
