In the tinnitus patients with low B12 vitamin levels, audiometric tests conducted after B12 vitamin treatment revealed a significant improvement in hearing levels only at the 250 Hz frequency. No change was observed at other frequencies.
Dietary factors can affect auditory system. There are several studies showing the negative impact of vitamin B12 deficiency on hearing function in adults. However, some studies have failed to find any evidence supporting such association.
Study Results
Participants in Group A with a vitamin B12 deficiency showed a significant improvement in their tinnitus severity index scores after receiving six weeks of B12 therapy.
B12 deficiency is associated with axonal degeneration, demyelination, and subsequent apoptotic neuronal death. Vitamin B12 deficiency may cause the demyelination of neurons in the cochlear nerve, resulting in hearing loss.
Research has shown that most tinnitus sufferers are deficient in vitamin B12. This nutrient can be found in dairy products, meat, and eggs, but it makes more sense to choose a supplement of 1,000mcg strength and take two daily for an accurate therapeutic dose.
Vitamin B12 is also known to potentially reduce the risk of tinnitus. Deficiencies in B2 (riboflavin) and B3 (niacinamide) can also be associated with tinnitus. Taurine, which is an amino acid that is often found in athletic supplements, can help reduce tinnitus as well.
As per the NHS, tinnitus noises can sound like ringing, buzzing, humming, whooshing, hissing, throbbing, music or singing. You can hear these noises in both the ears or in your head. These might come and go or you might even hear them all the time. But the symptoms can indicate a deficiency of vitamin B12.
University Hearing Researchers Recommend Vitamins A, C and E
University of Michigan researchers found that this nutrient mixture helps prevent noise-induced hearing loss by blocking the creation of free radicals.
Vitamin B12 deficiency can irritate and hamper the function of nerves in the ear. Research studies have shown that people with tinnitus experienced improvement in symptoms after undergoing vitamin B12 supplemental therapy.
There is no cure for tinnitus. However, treating an underlying cause (such as vitamin B12 deficiency) may help relieve tinnitus symptoms. Other possible treatment options include: Acoustic therapy or sound therapy.
What does the research say? Serum magnesium levels are lower in people with tinnitus than the general population[3]. Increased susceptibility to noise damage, ototoxicity and auditory hyperexcitability have also been linked to magnesium deficiency[4].
Magnesium therapy has been demonstrated in several studies to be effective in either preventing or treating hearing damage, particularly noise-induced hearing loss, but also in improving hearing loss associated with drug ototoxicity and sudden sensorineural hearing loss.
Folate/Folic Acid
Folic Acid and folate—the natural source of vitamin B-9—is essential to the function of inner-ear health, and has been proven to slow the decline of age-related hearing.

Safety and side effects. When taken at appropriate doses, vitamin B-12 supplements are generally considered safe. While the recommended daily amount of vitamin B-12 for adults is 2.4 micrograms, higher doses have been found to be safe. Your body absorbs only as much as it needs, and any excess passes through your urine ...
Brain Function
B12 is a key nutrient for nervous system health. It is important for producing serotonin and dopamine, which are mood-enhancing neurotransmitters. As a result, vitamin B12 can help to prevent and treat depression and anxiety. It can improve focus and memory as well.
Unfortunately, curing a hearing loss naturally is not currently possible. To restore hearing, intervention is generally required. This could be in the form of hearing aid devices. In some cases, surgical intervention can help restore hearing.
The delicate hair cells in the ear, which detect sound, are permanently degraded or damaged. For these people, there is no cure, but hearing better can be as simple as visiting a hearing care professional and being professionally fit with the right type of hearing aid.
A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as: vision problems. memory loss. pins and needles.
Abstract. Vitamin B12 deficiency can have distressing neuropsychiatric symptoms. It can have an etiological role in clinical presentations like depression, anxiety, psychosis, dementia, and delirium, requiring screening of at-risk populations.
