A new study points out the potential dangers of daily supplements, particularly in women.
Researchers say those who take multi-vitamins, folic acid and iron supplements may face higher risks of early death. The study, published in the Archives of Internal Medicine, measured tracked mortality of women over a 19-year period. Researchers found that women taking vitamin supplements died earlier than those women who did not take anything.
But the risks may be explained by ongoing health problems or people taking iron pills after major surgery. Dieticians say supplements aren't necessarily bad but should be secondary to proper nutrition.
Experts say more research is needed and people should talk to their doctors about what vitamins and supplements they might need.
