Global research trends and knowledge mapping of nutritional supplements in polycystic ovary syndrome: a bibliometric study (2006–2024)

Abstract This paper utilizes bibliometric methods to statistically analyse 1588 English-language articles published from 1 January 2006 to 31 December 2024 on nutritional supplements and polycystic ovary syndrome (PCOS). It systematically reviews the current state of the field, highlighting areas that require further in-depth research. This study identified research hotspots such as insulin resistance, oxidative stress, inositol, and vitamin D. The findings suggest that the management of PCOS through nutritional supplements is moving towards a more integrated, personalised, and multidisciplinary approach. This emerging trend offers a promising outlook for the development of more effective and comprehensive treatment options for patients diagnosed with PCOS in the future. Objective To identify research hotspots and reveal development trends in the field of nutritional supplements for improving polycystic ovary syndrome (PCOS), we conducted a bibliometric analysis of the literature related to this topic. The results were visualized to provide a comprehensive overview of the current state of research and to offer a foundation for future studies. Methods A search was conducted on the Web of Science Core Collection for articles and reviews published from 1 January 2006 to 31 December 2024, using the keywords "nutritional supplements" and "PCOS".Visualization analysis was performed using VOSviewer and CiteSpace. Results Through bibliometric analysis, this study revealed the current state of and trends in research on nutritional supplements for improving PCOS. Future research should focus on the feasibility of inositol and vitamin D to comprehensively improve PCOS. "Chromium supplementation " and gut nutrition have emerged as new research hotspots. Although the field currently has limitations, such as a lack of high-quality studies, nutritional supplements show great potential for PCOS treatment. Future research should explore the best application strategies for nutritional supplements, such as multi-nutrient combination therapy or personalized treatment plans, to provide more effective treatment options for PCOS patients.
