A RECENT REPORT on vitamin supplements, touted as deterrents for almost everything from cancer to aging, cautions that less may be more.
In reviewing studies done on vitamins A, C, folic acid and antioxidants, the federal Agency for Healthcare Research and Quality found that there is insufficient evidence to support their use as preventives for cancer and heart disease.
Some studies showed hat too much vitamin A may actually reduce bone density or damage the liver. Additional beta carotene, which has been recommended for those who smoke, may have a negative rather than positive impact, the agency reported.
People who use vitamins to ward off disease typically take megadoses. Recommended Daily Allowances of vitamins, however, may be necessary for those whose diets don't provide enough nutrients or for pregnant and nursing women, the report said.
People should talk to their doctors about dosage and generally stick to the Recommended Daily Allowances until more research is in, the report said. More information is available at www.ahrg.gov.
The review was done by the U.S. Preventive Services Task Force, an independent panel of private-sector experts sponsored by the agency. The task force assesses scientific evidence, primarily for physicians, on a range of preventive health issues.
