A growing number of tinnitus cases, particularly among young adults, may be linked to common vitamin deficiencies, according to leading health experts. The condition, characterized by phantom noises like ringing or buzzing, affects approximately 7.6 million adults, with a notable increase observed in younger demographics.
While tinnitus is often associated with hearing loss, loud noise exposure, or ear blockages, some specialists propose that deficiencies in iron, folate, and vitamin B12 could play a significant role. These three nutrients are vital for maintaining nerve health, specifically protecting the myelin sheath that insulates nerves.
Dr. Sue Pavord, a consultant hematologist at Oxford University Hospitals, explained that damage to the cochlear nerve, which transmits sound signals from the ear to the brain, can occur when its protective myelin sheath deteriorates due to insufficient levels of these vitamins. This damage can manifest as the ringing sensation associated with tinnitus.
Symptoms of deficiencies in iron, folate, or B12 can include fatigue, pale skin, and shortness of breath. Experts recommend that individuals experiencing these issues consult their general practitioner for a blood test to assess their vitamin levels. If a deficiency is identified, it can typically be treated with targeted supplements, such as iron tablets, folic acid pills, or vitamin B12 supplements or injections.
Some proponents are advocating for the National Health Service (NHS) to routinely test vitamin levels in tinnitus patients, believing that correcting such deficiencies could improve inner ear health.
Rachel Melinek, 44, shared her experience of suffering from tinnitus for several years, describing it as a high-pitched ringing and whooshing sound that made it difficult to relax or sleep. She also experienced persistent coldness, extreme tiredness, and brain fog. A blood test revealed she had a mild folate deficiency. Following her doctor's advice, Melinek adjusted her diet to include more folate-rich foods like beans and lentils and took a low-dose iron supplement. She also learned to manage her iron absorption by avoiding tea or coffee close to meals or supplements. Over time, she reported that her tinnitus became significantly less intrusive and now occurs only occasionally and with milder intensity.
Studies indicate that tinnitus among young adults has risen by over a third in the past two decades, now impacting about 2.3 million individuals in this age group. The primary cause is often linked to inner ear damage related to hearing loss, with experts pointing to factors like prolonged exposure to loud music through headphones as a common culprit for damage to sensory hair cells in the inner ear.
