Vitamin supplements are the favorite prescription for the average person: Am I tired? I'm taking iron supplements .. Am I sad? So there is a lack of traditional vitamin D.

But recent research on cardiovascular health, published in Analys of International Medicine, found that vitamin supplements have little effect on heart health, including heart disease and longevity in general.

Doctor Erin de said. Mikos, an associate professor of cardiology at the Johns Hopkins University School of Medicine in Baltimore and co-author of the research, said the research was done in part as a result of the growing popularity of the supplement industry.

"For the vast majority of vitamins, we have found no benefit either in reducing mortality or in cardiovascular health," Mikos said, although up to one in two people in the United States takes some form of supplement or vitamin.

The research reviewed evidence gathered from separate randomized clinical trials to analyze the utility of dietary intervention and supplementation in cardiovascular disease.

"This study confirms what we thought there were very few, if any, essential supplements or vitamins that people should take as long as they are on a healthy diet," said Jeffrey Linder, head of internal medicine and geriatrics at Northwestern University School of Medicine in Chicago. Adding that food contains both minerals and vitamins the body is designed to absorb.

While Chicago's cardiologist, Dr. Mark Rabat, pointed out that he can prescribe supplements only if patients have a lack of vitamins, and can benefit from them but this is not the majority.

"People take these things without consulting doctors because they think they are harmless, and they can have real side effects," Mikos said. However, Linder believes that the real danger is that patients waste their money in a misleading attempt to improve their health.
