Food supplement usage in seven Western states

Data on food supplement usage were collected from 2451 adults in seven Western states. No significant differences were determined among states. A majority (66.6%) of the sample used some form of food supplements, with 40.0% consuming one to three supplements per day. The archetype food supplement user was likely to be a young female with some college education, who believes that the nutritional quality of food has decreased in the last 10 yr and in the efficacy of supplements for disease prevention or cure, and primarily receives information concerning food and nutrition from books and health food stores. Correspondingly, one of the most frequently cited reasons for using food supplements, next to "to prevent colds and other illnesses" was "to make up for what is not in food." The three most frequently used food supplements, in rank order, were multiple vitamins, vitamin C, and multiple vitamins plus iron.
