Popping vitamins may do more harm than good, according to a new study that adds to a growing body of evidence suggesting some supplements may have health risks.
Researchers from the University of Minnesota examined data from more than 38,000 women taking part in the Iowa Women's Health Study, an ongoing study with women who were around age 62 at its start in 1986. The researchers collected data on the women's supplement use in 1986, 1997 and 2004.
Women who took supplements had, on average, a 2.4 percent increased risk of dying over the course of the 19-year study, compared with women who didn't take supplements, after the researchers adjusted for factors including the women's age and calorie intake.
"Our study, as well as other similar studies, have provided very little evidence that commonly used dietary supplements (http://us.lrd.yahoo.com/_ylt=Aj7CMxI2oCjPtIqb4bvEtzgbANEA;_ylu=X3oDMTFqMDg xZXM0BG1pdANBcnRpY2xlIEJvZHkEcG9zAzEEc2VjA01lZGlhQ XJ0aWNsZUJvZHlBc3NlbWJseQ--;_ylv=0/SIG=1329l6h7j/EXP=1319501996/**http%3A//www.myhealthnewsdaily.com/high-fiber-diet-better-than-supplements-1730/) would help to prevent chronic diseases," said study author Jaakko Mursu, an epidemiologist at the University of Minnesota School of Public Health.
"We would advise people to reconsider whether they need to use supplements, and put more emphasis on a healthy diet instead," Mursu said.
A toxic combination?
The new study linked a number of individual vitamins and minerals to the slight mortality risk, including multivitamins, vitamin B6, folic acid, iron, magnesium, zinc and copper.
For example, of the 12,769 women in the study who took a daily multivitamin, 40.8 percent had died by the end of 2008, whereas 39.8 percent of the 10,161 women who hadn't taken a daily multivitamin had died.
Mursu said that the design of the study did not allow the researchers to determine if there was a specific cause for the increased mortality.
"However, we do know that most compounds are toxic in high amounts, and long-term use might predispose [a person] to detrimental outcomes," he told MyHealthNewsDaily.
The increased chance of dying" could be related to generally high concentration of compounds that these supplements contain. Most supplements contain higher amounts of nutrients than would be derived from food, and it is known that several compounds can be toxic in higher amounts, especially when consumed for a long time, as some of these accumulate to body," Mursu said.
Taking calcium supplements (http://us.lrd.yahoo.com/_ylt=AoXQItn7gBeewnqjbMAELyMbANEA;_ylu=X3oDMTFqaWd 2Ymg3BG1pdANBcnRpY2xlIEJvZHkEcG9zAzIEc2VjA01lZGlhQ XJ0aWNsZUJvZHlBc3NlbWJseQ--;_ylv=0/SIG=12f742v1u/EXP=1319501996/**http%3A//www.myhealthnewsdaily.com/calcium-broken-bones-1543/), on the other hand, actually seemed to lower the women's death risk slightly, by 3.8 percent, although the researchers noted that there was not a relationship between consuming increasingly higher amounts of calcium and a continuing decrease in mortality rate.
Less is more
While vitamins and minerals are necessary for proper nutrition, excess intake has not shown further benefit, and recent studies have cast some doubt (http://us.lrd.yahoo.com/_ylt=AuIKpIwaBKW2qGpSEfD8kXIbANEA;_ylu=X3oDMTFqaTN jbzlmBG1pdANBcnRpY2xlIEJvZHkEcG9zAzMEc2VjA01lZGlhQ XJ0aWNsZUJvZHlBc3NlbWJseQ--;_ylv=0/SIG=139vjqr49/EXP=1319501996/**http%3A//www.myhealthnewsdaily.com/health-value-of-omega-3-fatty-acids-questioned-1980/) on the idea that vitamin supplements provide a "safety net" for people not getting enough of a given nutrient. Instead, too much may be a problem.
The study, published today (Oct. 10) in the journal Archives of Internal Medicine, is part of a series examining interventions in medicine that may be unnecessary.
"Until recently, the available data regarding the adverse effects of dietary supplements has been limited and grossly underreported. We think the paradigm "the more, the better" is wrong," wrote Dr. Goran Bjelakovic and Dr. Christian Gluud, of the Center for Clinical Intervention Research at Copenhagen University Hospital in Denmark in an accompanying commentary.
"We believe that for all micronutrients, risks are associated with insufficient and too-large intake. Low levels of intake increase the risk of deficiency. High levels of intake increase the risk of toxic effects and disease," they wrote.
"Therefore, we believe that politicians and regulatory authorities should wake up to their responsibility to allow only safe products on the market," they wrote.
