Study flags risk of daily vitamin use among older women

Older women who took a daily vitamin supplement — even just a multivitamin — had an increased risk of dying of cardiovascular disease and cancer, according to a study published Monday in the journal Archives of Internal Medicine.
Multivitamin users were just as likely as non-users to have died or been diagnosed with common cancers or suffered a heart attack or stroke.
The study highlights concerns about the long-term use of supplements and vitamins in people who do not have severe nutritional deficiencies, the authors say. An accompanying editorial notes that findings "add to the growing evidence demonstrating that certain supplements can be harmful."
Previous studies have raised questions about the value of supplements and vitamins, but researchers and nutrition experts call these new findings "puzzling" and say more research is needed.
About half of adults in the USA take multivitamins. Annual vitamin and supplement sales total more than $20 billion.
