October 10, 2011 — The current study sought to evaluate the link between supplement use and total mortality rate, using data from the Iowa Women's Health Study...Vitamin B6, folic acid, iron, magnesium, and zinc were associated with about a 3% to 6% increased risk for death, whereas copper was associated with an 18.0% increased risk for total mortality when compared with corresponding nonuse.
"In contrast, we found that several commonly used dietary vitamin and mineral supplements, including multivitamins, vitamins B6, and folic acid, as well as minerals iron, magnesium, zinc, and copper, were associated with a higher risk of total mortality."
"Although we cannot rule out benefits of supplements, such as improved quality of life, our study raises a concern regarding their long-term safety," the authors add.
"We cannot recommend the use of vitamin and mineral supplements as a preventive measure, at least not in a well-nourished population,"
