Consumers’ Information-Seeking Behaviors on Dietary Supplements

Background Consumers are advised to seek information about dietary supplements (DS) before using them; little is known concerning whether this recommendation is heeded. Objective The objectives of this pilot study were to investigate whether users of DS seek information about these products before using them and particularly whether such information is sought from health-care professionals (HCPs). Methods Surveys administered face-to-face to adult consumers at three venues in New York City. Results Between November 2017 and October 2018, 199 consumers were surveyed. Of the 139 (70%) DS users, 104 (75%) used at least one DS that was not prescribed/recommended by an HCP. Of those, 88 (85%) reported seeking information about DS before using them and two (2%) noted that for some they do and for some they do not. The source of information most frequently used was the Internet (76; 84%). Pharmacists, dietitians/nutritionists, and medical doctors were reported to be a source of information by seven (8%), six (7%), and five (6%) of the respondents, respectively. DS were most commonly purchased at a pharmacy (76; 54%). Of the 199 participants, 111 (56%) perceived DS to be “very safe” or “safe,” while 20 (10%) reported that DS were “unsafe” or “very unsafe”; 60 (30%) participants were “neutral.” Conclusion Although most DS users sought information prior to using them, the majority did so by using the Internet and only a few consulted with an HCP. HCPs should be proactive in educating consumers about the importance of consulting with them prior to using these products.
