These two functions are influenced by a variety of factors, including vitamins. In this article, we will examine the role of vitamins on hearing and balance, and the effects of deficiencies in these nutrients on ear and balance health. Materials and Methods: This review examined the effects of vitamins on hearing. We identified 71 studies published since 2000 through searches of Medline (PubMed), Google Scholar, ScienceDirect, PubMed, EBSCO, ASHA, Thieme and the ProQuest. Results: Evidence suggests that vitamins A, B, C, D, and E are associated with auditory and vestibular health. Deficiencies in these vitamins have been linked to hearing loss, tinnitus, dizziness, and impaired inner ear function. In particular, vitamins A and E support hair cell integrity and protect against oxidative stress, while B and C vitamins contribute to neural function. Vitamin D is also important for vestibular health through its role in calcium regulation. Conclusion: Ensuring adequate intake of these vitamins through diet or supplementation may help prevent hearing and balance disorders and improve quality of life https://jmr.tums.ac.ir/index.php/jmr/article/view/1429
