Contrary to what many might believe, vitamins and minerals may be risky. Risks associated with the use of common dietary vitamin and mineral supplements in older women may include higher mortality rates.
Researchers examined vitamin and mineral supplement use in relation to total mortality in 38,772 older women (mean age 61.6 years at baseline in 1986). Vitamin B6, folic acid, iron, magnesium, zinc, and copper were all associated to some extent with increased risk of mortality when compared with non-use. The association was strongest with supplemental iron, but in contrast to other findings, calcium was associated with decreased risk.For more information, the research is part of the Iowa Women’s Health Study and was reported in the Archives of Internal Medicine, 2011; 171(18):1625-33 (ISSN: 1538-3679)
