KHOU-TV (CBS) Ch. 11 Houston TX (Internet / TV) 05/18/06 (no weblink available) Over half of U.S. adults use multivitamins, mostly the pretty healthy people who also eat nutrient-fortified foods. Yet there’s little evidence that most of the pills do any good—and concern that some people may even get a risky vitamin overload, advisers to the government said Wednesday. Dr. Victor Sierpina, associate professor of family medicine at the University of Texas Medical Branch at Galveston, was quoted in a story on KHOU Channel 11 about a National Institutes of Health report on the efficacy of vitamin and mineral supplements. Sierpina pointed out the importance of eating whole foods to prevent vitamin deficiencies.
