Purpose: The aim of this study was to evaluate the use of probiotic products in Hungary, to explore consumers' knowledge of probiotics, and to gain information about the main characteristics of current usage. Materials and Methods: The research used a self-developed explorative questionnaire to obtain the necessary information. The data collected was further analysed with IBM SPSS 25.0 and Microsoft Office Excel. Results: Nearly three-quarters of respondents (73.9%) have used probiotics in their life. Those who have already used these products, mostly heard about them from doctors (62.8%) and friends/relatives (40.5%), while among non-users the main sources of information were web pages (46.8%) and commercials (45.2%). Conclusions: We found several differences between users and nonusers in terms of probiotics awareness. Consequently, healthcare providers may play an important role in the process of careful product choice and proper usage.  Kulcssazvak: probiotics, survey method, dietary supplements, consumer preferences
