Zinc, a key regulator in the central nervous system, exerts multiple biological functions beyond maintaining neurotransmitter homeostasis, including inhibiting neuroinflammation, restoring neuroplasticity, and modulating gut microenvironmental homeostasis. This review summarizes the evidence linking zinc deficiency to the onset and development of depression, with a specific focus on the role of gut microbiota. It also discusses different forms of zinc supplements, highlighting synergistic interventions that combine novel zinc complexes with probiotics. Together, these lines of evidence provide a theoretical basis for innovative adjunctive strategies for depression.<\/jats:p>","DOI":"10.3390\/nu18162584","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T08:01:36Z","timestamp":1786089696000},"page":"2584","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Zinc and Depression: From Neurobiological Functions to Gut\u2013Brain Interactions"],"prefix":"10.3390","volume":"18","author":[{"given":"Haichuan","family":"Li","sequence":"first","affiliation":[{"name":"School of Public Health, Lanzhou University, Lanzhou 730030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4441-2766","authenticated-orcid":false,"given":"Jiazhang","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tian","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Public Health, Lanzhou University, Lanzhou 730030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenchuang","family":"Tang","sequence":"additional","affiliation":[{"name":"Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qirui","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Public Health, Lanzhou University, Lanzhou 730030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Gong","sequence":"additional","affiliation":[{"name":"School of Public Health, Lanzhou University, Lanzhou 730030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Public Health, Global Health Institute, Marshall University, Huntington, WV 25703, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1116-8290","authenticated-orcid":false,"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Public Health, Lanzhou University, Lanzhou 730030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pastis, I., Santos, M.G., and Paruchuri, A.
