To aid in supporting its mission under the Dietary Supplement Health and Education Act of 1994 (DSHEA), the Food and Drug Administration sponsored studies on producers and consumers of dietary supplements, and the range of dietary supplement products available in the marketplace. From these recently completed studies, this paper describes characteristics of the dietary supplement industry and summarizes label information from selected products offered for sale in retail stores, mail-order catalogs, and Internet sites. In addition, we provide examples of recent uses of the dietary supplement market information from these studies. Key Words: Dietary supplements; Marketplace; Labeling; Product claims
