Science still scanty on supplements, health group finds

Vitamin and mineral supplements are often marketed as though they were magic bullets for the prevention and treatment of all sorts of diseases—from the common cold to cancer. But is there solid scientific evidence that these supplements are effective? No, say physicians and scientists associated with the American Council on Science and Health (ACSH) in the second edition of its report, Vitamins and Minerals: Does the Epidemiologic Evidence Justify General Supplementation? The health group reports that the available evidence does not justify recommendations that healthy people take supplements to prevent disease.

Much of the scientific evidence that suggests vitamins and minerals may prevent disease stems from epidemiological studies that document lower rates of heart disease and cancer in populations with a high consumption of fruits and vegetables. Since these foods are rich in vitamins and minerals, many assume that supplements of these nutrients can decrease the risk of disease.

"The data do not substantiate this reductionist approach," states Dr. Ruth Kava, Director of Nutrition at ACSH. "In fact," she continues, "large, well-controlled clinical trials of supplements in healthy people do not show significant benefits. And in some groups, some supplements may increase the risk of disease."
