Background: Although dietary supplements (DS) are widely sold in pharmacies, the legal, ethical, and practice responsibilities of pharmacists with respect to these products have not been well defined. This systematic review of pharmacists' attitudes, knowledge, and professional practice behaviours toward DS is intended to inform pharmacy regulators' and educators' decision making around this topic. Methods: Eligible studies were identified through a systematic database search for all available years through to March 2006. Articles were analyzed for this review if they included survey data on U.S. or Canadian pharmacists' attitudes, knowledge, or professional practice behaviors toward DS published in 1990 or later. Results: Due to the heterogeneity of the data, it was not possible to draw a conclusion with respect to pharmacists' general attitudes toward DS. Approximately equal numbers of pharmacists report positive as well as negative attitudes about the safety and efficacy of DS. There is strong agreement among pharmacists for the need to have additional training on DS, increased regulation of DS, and quality information on DS. In addition, survey data indicate that pharmacists do not perceive their knowledge of DS to be adequate and that pharmacists do not routinely document, monitor, or inquire about patients' use of DS. Despite this, a large proportion of pharmacists reported receiving questions about DS from patients and other health care practitioners. Conclusion: Further research is needed to explore the factors that influence pharmacists' beliefs and attitudes about DS, to accurately evaluate pharmacists' knowledge of DS, and to uncover the reasons why pharmacists do not routinely document, monitor, or inquire about patients' use of DS.
