rtant cause of blindness in adults), was first added to many popular multivitamins in late 1999 and 2000. Another antioxidant, lycopene, was added to major multivitamins in 2003 as a cancer preventative. "The addition of these supplements to multivitamin products has signaled two subtle, but important, changes in recent years," the researchers suggest. "First, the acceptance of herbal supplements and other dietary supplements as part of the mainstream health milieu has apparently increased. Second, the marketing strategy for multivitamin products appears to have broadened from supplying recommended daily allowances of vitamins and minerals that may be lacking in the diet to preventing chronic disease, such as macular degeneration and cancer."

"Approximately one quarter of adults in the United States use multivitamins, and this prevalence may increase following the recent recommendation that all adults take a multivitamin daily," the authors write. "Although the deliberate use of herbal products may have reached a plateau in the last few years, exposure to individual herbal ingredients may continue to rise as more of them are added to mainstream multivitamin products."
