Despite the rapid growth of the dietary supplement market, little is known about the reasons people take supplements. Awareness of the number of persons using dietary supplements, as well as the range of products they use and their reasons for using them, may help practicing physicians improve their communications with patients.1 In this article, we present findings from a recently conducted nationwide public survey about dietary supplements to report on the purposes for which supplement users take these products and which types they use.

The data are derived from a survey conducted by the Harvard Opinion Research Program at the Harvard School of Public Health, Boston, Massachusetts. Fieldwork was conducted via telephone (landline and cell phone) for the Harvard Opinion Research Program by SSRS of Media, Pennsylvania, from August 11 to September 7, 2011, among a national representative sample of 1579 respondents 18 years and older. The interviews were conducted in English and Spanish. Responses were weighted according to US Census data to reflect the demographic makeup of the adult population. The margin of error is plus or minus 2.9 percentage points for total respondents at the 95% confidence level and plus or minus 4.8 percentage points for the 584 dietary supplement users.
