Additional InformationScope and Methodology
This report covers nutritional substances used to enhance sports performance, and sold at retail through such outlets as health food chains and single health food stores, drugstores, mass merchandisers, gyms and health clubs, sporting goods stores, bike shops, multi-level marketing, mail order, and the Internet. The report does not cover sup-plements used for general health or preventive reasons, or for non-sports treatment; diet supplements; supplements used for non-nutritional purposes; nutritional substances sold at the institutional level; or nutritional substances used as ingredients to produce nutri-tional products. Sports beverages sold within a line of sports nutritionals are included; however, the report does not cover mainstream sports beverages sold mainly as refresh-ment drinks, such as Gatorade.
The information contained in this report was obtained from both primary and sec-ondary research. Primary research entailed in-depth, on-site examinations of health and natural food stores, drugstores, mass merchandisers, supermarkets, sporting goods stores, bike shops, and health clubs. Extensive company, distributor, and retailer interviews were conducted to obtain information on regulatory issues, marketing programs, and new products pertaining to the sports nutritionals market. Secondary research entailed data gathering from relevant sources. Included were consumer and industry publications, newspapers, government reports, financial reports, company literature, and corporate an-nual reports. Because a large share of sports nutritional sales occurs in chain and single health food stores, which are not monitored by tracking services, total retail sales of sports nutritional products can only be estimated. For the health and natural food sector, Packaged Facts has relied on data published by four trade magazines—Health Foods Business, Natural Foods Merchandiser, Vitamin Retailer, and Whole Foods—supplemented by interviews with marketers and other trade sources. For the mass-market sector, Packaged Facts derived figures from available data from Information Resources, Inc. (IRI) and various trade publications. Figures provided on national consumer advertis-ing expenditures are based primarily on Competitive Media Reporting (CMR) data, as reported in the trade press. The analysis of consumer demographics is derived from Simmons Market Research Bureau data for spring 1998.
