A surge in tinnitus cases, affecting an estimated 7.6 million adults, may be linked to common vitamin deficiencies, according to leading medical experts. The condition, characterized by phantom noises such as ringing, hissing, or buzzing, has seen a notable rise, especially in younger populations.
While tinnitus is often associated with hearing loss, loud noise exposure, or ear blockages, some specialists are pointing to deficiencies in essential nutrients like iron, folate, and vitamin B12. These vitamins play a crucial role in maintaining nerve health, particularly the myelin sheath that protects nerves. Damage to the cochlear nerve, which transmits auditory signals from the ear to the brain, can occur if this protective covering is compromised due to a lack of these vitamins, potentially leading to the perception of ringing.
Dr. Sue Pavord, a consultant hematologist at Oxford University Hospitals, explained that iron, folate, and vitamin B12 help protect and maintain the myelin that covers nerves. Without sufficient amounts, nerves can become damaged, including the cochlear nerve. This damage can manifest as tinnitus.
One individual's experience highlights this potential link. Rachel Melinek, 44, suffered from persistent high-pitched ringing and whooshing sounds for several years, which made relaxation and sleep difficult. She also experienced symptoms such as feeling unusually cold, extreme tiredness, and brain fog. A blood test revealed she had a mild folate deficiency. Following her doctor's advice, Melinek adjusted her diet, increasing intake of folate-rich foods like beans and lentils, and took a low-dose iron supplement. She also noted changes in absorption, reducing caffeine and certain foods around iron-rich meals or supplements.
Over time, Melinek reported a significant reduction in the intrusiveness of her tinnitus, stating it now occurs only occasionally and is much milder. Experts suggest that identifying and treating such deficiencies could improve the health of the inner ear for tinnitus sufferers. The common symptoms of iron, folate, and B12 deficiencies include fatigue, pale skin, and shortness of breath, prompting experts to recommend that individuals experiencing these issues consult their GP for blood tests. Deficiencies can be treated with targeted supplements, such as oral iron tablets, folic acid pills, or vitamin B12 injections or oral supplements.
Studies indicate that tinnitus among young adults has increased by over a third in the past two decades, now affecting approximately 2.3 million. Experts believe that damage to the sensory hair cells in the inner ear, often triggered by factors like listening to music at high volumes through headphones, is a primary cause. However, the potential contribution of vitamin deficiencies is gaining attention as a treatable factor that could alleviate symptoms for a significant number of individuals.
