(1) Background: Regulations governing food supplements vary considerably across countries, allowing products that are prohibited in one jurisdiction to be legally sold in another. Furthermore, online sales enable and facilitate this practice. Regarding pharmaceutical malpractice, the absence of a standardized European framework complicates the evaluation of pharmacist liability. As a result, the specific elements of the liability framework are defined by the national legislation of each Member State. The aim of our review is to map the global regulatory landscape of food supplements and to examine the pharmacist’s professional responsibilities, including instances of malpractice related to this area. (2) Methods: A literature review covering publications from January 2020 to December 2024 was performed using four databases: Scopus, PubMed, Embase, and Web of Science. The search retrieved 8243 records, of which 77 studies fulfilled the eligibility criteria. The extracted data were organized into five main themes: pharmacist responsibility and malpractice, food supplement regulation, consumer safety, health claims, and pharmacist knowledge. (3) Results: The literature reviewed indicated a relatively low number of malpractice cases within the pharmacy profession compared to other professions. A higher incidence of cases is observed among male pharmacists and those practicing in the private sector. Notably, no cases have been identified addressing pharmacists’ responsibilities in the dispensing of food supplements. In the context of food supplement regulation, the reviewed literature highlights a lack of standardized terminology and harmonized legislation across different jurisdictions. Therefore, products may be classified differently across jurisdictions. Another observed barrier is the considerable variation in market access requirements across countries. Regarding consumer safety, several irregularities have been observed. Substantial non-compliance in both product composition and labeling has been observed, reflecting insufficient quality control measures. Concerning health claims, significant regulatory non-compliance with European Union regulations has been documented. In addition, widespread misleading advertising practices have been observed. With respect to pharmacists’ knowledge, the reviewed literature identifies several professional challenges within pharmacy practice, particularly those concerning the dispensing of food supplements. (4) Conclusions: This research offers a comprehensive analysis of the literature published over the past five years concerning pharmaceutical malpractice cases, as well as an examination of food supplement regulation and the professional responsibilities of pharmacists. A recurring barrier identified is the absence of unified regulatory frameworks worldwide. This results in uncertainty concerning the pharmacist’s professional role and responsibilities.

Introduction. The advertising of food supplements on various media channels or in specialty stores with natural products and other places, as well as the lack of informative and educational programs for the population upon side effects and the interaction of food supplements with food and drugs, have led to the development of uncontrolled marketing of these products. Material and methods. PubMed, ResearchGate and EUR-Lex databases were analyzed during 2015-2021, based on search criteria based on: adverse reactions, ingredient new food, food supplements, algorithms. Results. Certain dietary supplements can cause multiple side effects, such as: impaired platelet function by decreased platelet aggregation, gastrointestinal side effects (diarrhea, vomiting), decreased wound healing/epithelialization, bacterial or fungal sepsis, most common in patients older. Herbal resources such as Aloe vera, Matricaria recutita, Taraxacum officinale and others, can cause dermatological side effects and inhibit the elimination of dermatological drugs metabolised by cytochrome P-450 (e.g. terbinafine). Matricaria recutita, Allium sativum, Mentha piperita L. and others, inhibit the enzyme CYP2C9. Another enzyme with a role in the metabolism of dermatological drugs and which is inhibited by plant resources is CYP3A4. Conclusions. It is imperative to legislate the reporting of adverse reactions caused by food supplements, including their interaction with food or drugs.
