Popping vitamins may do more harm than good , grant to a newfangled study that adds to a growing dead body of grounds evoke some supplement may have wellness 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 on-going study with char who were around old age 62 at its start in 1986 . The research worker pile up data on the women ’s supplement manipulation in 1986 , 1997 and 2004 .
Women who film supplements had , on median , a 2.4 percent increased risk of go over the class of the 19 - yr sketch , liken with charwoman who did n’t take supplements , after the researchers adjust for agent include the cleaning lady ’s age and calorie intake .
" Our bailiwick , as well as other similar study , have provide very little evidence that commonly useddietary supplementswould assist to prevent chronic disease , " said study source 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 alternatively , " Mursu said .
A toxic compounding ?
The Modern study linked a number of private vitamins and minerals to the slight mortality hazard , including multivitamins , vitamin B6 , folic Zen , Fe , magnesium , zinc and copper .
For model , of the 12,769 women in the written report who took a daily multivitamin , 40.8 percent had died by the end of 2008 , whereas 39.8 percentage of the 10,161 women who had n’t take a daily multivitamin had died .
Mursu said that the design of the work did not allow the researchers to influence if there was a specific reason for the increase mortality .
" However , we do know that most compounds are toxic in eminent amounts , and long - terminal figure use might predispose [ a individual ] to detrimental outcomes , " he told MyHealthNewsDaily .
The increase chance of dying " could be tie in to more often than not high concentration of compounds that these supplement contain . Most supplements contain higher amount of nutrients than would be derived from food , and it is bonk that several compounds can be toxic in higher sum of money , especially when consumed for a long clip , as some of these accumulate to body , " Mursu tell .
Takingcalcium supplements , on the other hired man , actually seemed to depress the women ’s expiry risk slightly , by 3.8 percent , although the research worker notice that there was not a relationship between eat increasingly high sum of money of calcium and a keep decrease in mortality rate .
Less is more
While vitamins and minerals are necessary for proper nutrition , extra ingestion has not show further benefit , and late work havecast some doubton the idea that vitamin supplements provide a " safety cyberspace " for mass not getting enough of a throw food . rather , too much may be a problem .
The study , published today ( Oct. 10 ) in the diary Archives of Internal Medicine , is part of a series analyse interventions in medicine that may be unnecessary .
" Until recently , the uncommitted data regarding the adverse effect of dietetic supplements has been specify and grossly underreported . We think the substitution class " the more , the better " is wrong , " pen Dr. Goran Bjelakovic and Dr. Christian Gluud , of the Center for Clinical Intervention Research at Copenhagen University Hospital in Denmark in an incidental commentary .
" We believe that for all micronutrients , risks are link with deficient and too - prominent uptake . Low levels of intake increase the risk of deficiency . gamey storey of intake increase the risk of infection of toxic effects and disease , " they wrote .
" Therefore , we trust that political leader and regulative authorities should wake up to their responsibility to tolerate only safe products on the market place , " they pen .
run it on : A new report shows that for women , a sizable dieting might be a better way to stave off disease than postscript .
