A bibliometric snapshot of Turkish and international publications on oral dietary supplements
Abstract
Aims: This study aimed to compare Turkish-origin and international publications indexed in PubMed on oral dietary supplements in terms of temporal distribution, methodological characteristics, and research approaches.
Methods: This descriptive bibliometric study analyzed 40 articles indexed in PubMed. Articles were retrieved on December 2, 2025, using the search query (“dietary supplements” OR “oral supplement”) AND (“Turkey” OR “Türkiye”). The first 20 Turkish-origin and 20 international articles, which were sorted by the “best match” option and screened sequentially from the top of the results list and met inclusion criteria were analyzed. Variables including publication year, number of authors, article views, submission-to-acceptance time, study design, and research approach were extracted. Statistical analyses were performed using non-parametric tests and logistic regression, with p < 0.05 considered significant.
Results: A total of 40 articles were included. Turkish-origin publications were predominantly published in 2024–2025 (70.0%), whereas international publications were mainly concentrated in 2021–2023 (65.0%) (p=0.018). Quantitative research approaches were more frequent in Turkish-origin studies (65.0%), while qualitative methods predominated in international publications (70.0%) (p=0.056). International articles had significantly higher article views compared to Turkish-origin articles (median: 26,247 vs. 3,272; p<0.001). Logistic regression analysis demonstrated that quantitative research approach was independently associated with Turkish-origin publications (OR: 4.28; 95% CI: 1.09–16.80; p=0.037).
Conclusion: Turkish and international research on oral dietary supplements differ significantly in terms of publication timing and methodological orientation. The recent increase in Turkish-origin studies suggests growing national research activity, whereas international literature reflects earlier engagement and greater methodological diversity. These findings highlight the need for methodological diversification and closer alignment with global research trends to enhance the impact and visibility of future studies.
