Abstract Background Food supplements are widely used, but they can be dangerous if used inappropriately, as they often interaction with patients’ treatment. Their misuse has public health and patient out-of-pocket expenditure implications; general practitioners (GPs) play a central role in managing patient safety. This study aims to investigate the knowledge, attitudes and practices (KAP) of Italian GPs’ toward the use of food supplements. Methods From March to April 2024, an online survey was conducted via the EU-Survey platform among Italian GPs invited through their professional organization. The 62-question survey, adapted from a tool used among pharmacists, comprises two sections: A) KAP questions (28 true/false, 34 on a 5-point Likert scale) and B) socio-demographic questions (i.e. age, sex, years of experience, urban/extra-urban environment). Survey reliability was evaluated using Cronbach alfa and responses were analysed to look for differences between sub groups using Kruskal Wallis Test. Results 202 GPs participated in the survey, 46.0% were male, 53.5% female and 0.5% non-binary, with a mean age of 47±2 years. The majority (70.3%) came from an urban environment and 54.9% worked in group medicine. Only 53.5% of GPs showed an adequate knowledge of the topic (more than 60% of correct answers), with a mean of 18 correct answers. The overall reliability of the test was evaluated as acceptable (alfa>0.7). The 99.5% of GPs interview agreed (score 4 or more on the Likert scale) that they have an important role in food supplements prescription and 98% are involved in life styles counselling activities, but only 66.3% felt they have adequate formation on the topic. No statistically significant differences between population groups were found (p < 0.05). Conclusions Although GPs have recognized their key role in prescribing food supplements, there seem to be a general lack of knowledge on the subject that requires targeted educational interventions to ensure patient safety. Key messages • Food supplements are often taken by patients because they are under the impression that these products are always and completely safe. • Clinical recommendations for the use of food supplements are much more limited than their actual use.
