Exploring the Dietary Supplement Use During COVID-19: Insights from Community Pharmacists, Pharmacy Staff, Academics, and Industry Experts.

Introduction: The increased use of dietary supplements is a consequence of the coronavirus disease 2019 (COVID-19) pandemic. Although their efficacy has not been consistently proven, they have been perceived as a preventive tool against COVID-19. Less strict regulations and debates on their definitions in a regulatory framework raise concerns about safety issues. Apart from dietary supplement use, information demand has increased, and pharmacists have played a key role as accessible health professionals. This study aimed to reveal the opinions of community pharmacists, pharmacy staff, sector representatives, and academicians regarding the sale and use of dietary supplements during the COVID-19 pandemic. Methods: A qualitative study approach was followed, using grounded theory. Data were collected between September 2021 and July 2022, analyzed using MAXQDA 2020 software, and reported according to the Consolidated Criteria for Reporting Qualitative Research. Results: After refining the open codes, two themes emerged: dietary supplements and the effects of the pandemic. It was found that increased dietary supplement use was rooted in COVID-19 fear, promotional activities, and social media influence. The interaction between consumers and the dietary supplement industry is bidirectional. Conclusions: Pharmacies, as access points for these products, played a crucial role in struggling with the effects of the pandemic. Although dietary supplements are considered safe, their potential for adverse reactions poses a public health risk. Flexible regulations, unregulated alternative advertising channels, and a lack of awareness of the safety of these products pose a challenge to public health. In this regard, all stakeholders should work to minimize the risks from undergraduate education to professional life.
