Hearing loss affects millions of people worldwide. Significantly, therefore, a recent systematic literature review reveals a fascinating link between vitamin B12 deficiency and hearing loss, finding that maintaining optimum levels of this important micronutrient may play a key role in preventing the problem.
Published in the Ear, Nose & Throat Journal by researchers from India, the review initially examined a total of 612 studies. These were eventually narrowed down to 9 high quality papers. Analysis revealed that people with lower levels of vitamin B12 tend to have a higher prevalence of hearing impairment than those with normal or elevated levels. The researchers found that lower levels are associated with slight to mild hearing loss and that cochlear dysfunction and poorer hearing thresholds are linked to deficiency. These findings, the review concluded, highlight the importance of maintaining optimal levels of B12 for preserving hearing health.
