    Can vitamin supplements do more harm than good?

    Wasting money on vitamin supplements that may not work is one thing. But what if those same pills actually harmed you? That's the question raised by an analysis of 68 clinical trials of vitamin supplements involving almost a quarter of a million participants.

    It found people taking vitamin A supplements are 16 per cent more likely to die than those not taking supplements within the trial period, while beta-carotene and vitamin E supplement-takers are at 7 and 4 per cent greater risk (The Journal of the American Medical Association, vol 297, p 842).

    "There's absolutely no benefit from taking these supplements, and I would suggest people avoid them," says Christian Gluud of Copenhagen University Hospital in Denmark, who co-led the study.

    Supplement manufacturers are claiming many of the trials included people who were already sick. "You can't expect an antioxidant supplement to reverse 20 years of chronic smoking," says Judy Blatman of the Council for Responsible Nutrition in Washington DC, which represents US supplement makers.
    Gluud stands by his results, however. "Seventy per cent of the participants were healthy," he says.

    but if you factor in that 30% of them were ALREADY sick... anybody know a formula to figure out how much that effected the results?
