Abstract Objective This study aims to employ bibliometric methods for a visual analysis of the intersection between trace elements and immunity. It investigates the research hotspots and development trends in this field and offers a reference for clinical practice and future research. Methods We retrieved publications on micronutrient immunology from the Web of Science Core Collection for the period between January 2000 and December 2022. The bibliometric and visualization analysis was conducted using CiteSpace and VOSviewer. Results Through screening, we identified a total of 1392 relevant publications, with a consistent increase in the publication count over the years, particularly post-2019. China and the Chinese Academy of Sciences emerged as the most productive country and institution, respectively, in this research area. However, their influence was comparatively lower than that of Europe and the United States. Collaboration between authors and institutions from different regions was found to be weak. The journal Biological Trace Element Research exhibited significant activity in this field. Our analysis resulted in the classification of research areas into 9 clusters, including nutritional support, COVID-19, vitamins, selenium, inflammatory bowel disease, liver disease, the elderly, systemic inflammation, and pathogenesis. The research frontiers encompass gut microbiota, inhibition, and human health. Conclusion The results of our bibliometric analysis suggest promising prospects for the development of micronutrient immunology. Current research endeavors focus on the impact of gut microbiota on immune response, the role of trace elements in the immunotherapy of COVID-19, systemic inflammation, and cancer, as well as the influence of dietary nutrition on human health.
