    Women taking multivitamins don't live longer than those who don't take the pills, and might actually die sooner, a huge new study has found.

    The study involved about 39,000 women who were between the ages of 55 and 69 when the study began and were tracked for 19 years.

    During that time, about 40 per cent of them died. When the researchers looked at who took vitamins, those who chose multivitamins had a slightly higher risk of death than those who took no supplements at all. The same was found for women who regularly took iron, vitamin B6, folic acid, magnesium, zinc and copper.....

    Vitamin E pills raise prostate cancer risk, study suggests
    By Rita Rubin, Special for USA TODAYUpdated 14h 17m ago

    Vitamin E supplements significantly increased the risk of prostate cancer in healthy men even after they stopped taking them, scientists report today.

    Given the popularity of vitamin E for those 60 and over, the researchers wrote, "the implications of our observations are substantial." Those studied took 400 international units (IUs) a day.

    The prostate cancer findings come a day after publication of a study that raised questions about the effects of common vitamin and mineral supplements in older women. That 19-year study of nearly 39,000 women linked supplement use to a higher risk of death.

    "I think many Americans view supplements as an insurance policy," says Lori Minasian, a co-author of the vitamin E and prostate study and acting director of the Division of Cancer Prevention, National Cancer Institute.

    "We don't always exercise right, we don't always eat right. It's just easier to take a pill," she says.

    In Minasian's study, about 35,000 U.S. and Canadian men were randomly assigned to take vitamin E, selenium, vitamin E and selenium or a placebo. Black men, who have a higher risk of prostate cancer, were 50 and older. The other men in the study were at least 55.

    In 2008, after the men had been taking their pills for about 5 years, researchers told them to stop, a year earlier than planned. An interim analysis had shown that vitamin E wasn't reducing prostate cancer risk and might raise it, although that observation could have been due to chance.

    Once the men stopped, researchers expected the difference in prostate cancer risk between those on vitamin E and those on the placebo would even out, but it continued to widen. By July of this year, 17% more prostate cancers, 91 more cases, had been reported in those on vitamin E. than those on placebo pills, says the study, in the Journal of the American Medical Association.

    The authors say they don't have an explanation for their findings, which differ from other large randomized trials that examined the effect of vitamin E pills on prostate cancer risk. Perhaps the men taking E had higher levels to begin with.

    Urologist Neil Fleshner of Princess Margaret Hospital in Toronto, thinks the increased risk in the study was "just a statistical thing."

    "I don't think it's cause and effect," says Fleshner, who was not involved in the study. "Many other studies have looked at this question and not shown that."

    He says he used to take 800 units of vitamin E every day. "I truly believed it would help prevent prostate cancer." He stopped taking it when research a few years ago suggested large doses might increase risk of death.
