Research into the effects of dietary supplements, such as vitamin B12, on tinnitus is limited. However, some older studies indicate that there may be a link between tinnitus and vitamin B12 deficiency.
Tinnitus refers to a ringing sound in the ears that has no external source. Some people may wish to try dietary supplements, such as vitamin B12, to help with the condition.
This article discusses whether vitamin B12 can treat tinnitus, the recommended daily intake for vitamin B12, treatment for tinnitus, and when to speak with a healthcare professional.
People following a vegan or vegetarian diet often need to supplement with vitamin B12 to prevent deficiency, as they limit animal products in their diet. However, the majority of people in the United States obtain all the vitamin B12 they need from their diet.
According to a
Additionally, the authors suggested that participants who reported improvements after taking supplements may have experienced a placebo effect. Overall, the authors concluded that healthcare professionals should not recommend dietary supplements to manage tinnitus.
Low levels of vitamin B12 damage the nerves in the cochlea, a fluid-filled structure in the ear that is vital for hearing. Deficient vitamin B12 levels may also lead to damage in the tiny blood vessels in the ear. Both factors could contribute to tinnitus symptoms.
Additionally, study participants with vitamin B12 deficiency and tinnitus reported a reduction in tinnitus symptom severity following therapy with vitamin B12 injections. However, study participants without vitamin B12 deficiency reported hardly any reduction in tinnitus symptom severity with the same therapy.
People with tinnitus may benefit from speaking with a doctor about their vitamin B12 intake. A healthcare professional can also provide guidance about using dietary supplements safely.

Vitamin B12 is present in a range of foods, including:
- milk and other dairy products

- some fortified breakfast cereals and nutritional yeasts
Dietary supplements are also available for those who do not consume enough vitamin B12 as part of their diet. A person should speak with their doctor before taking any dietary supplements.

Cognitive behavioral therapy (CBT)
Tinnitus can be emotionally draining. However, therapists using CBT may teach people with the condition new ways to process and cope with the constant noise.
Some people with tinnitus may find that masking the ringing sound helps them reframe tinnitus as a neutral sound.

A doctor might also discuss the benefits of hearing aids with people whose tinnitus accompanies hearing loss. Some hearing aid products have sound-masking features that support tinnitus treatment.
For some people, sleeping through tinnitus symptoms
Taking melatonin was associated with a reduced severity of tinnitus and higher quality sleep in a limited
A person may also find taking steps to improve their sleep hygiene to be useful.
Not all tinnitus symptoms are ongoing or disruptive to daily life. For example, being around loud speakers at a concert may cause a person to experience temporary tinnitus symptoms.
However, a person should consider speaking with a doctor if tinnitus symptoms:
- do not go away after a few weeks
- interfere with work, sleep, or other factors that directly affect their quality of life
- occur alongside hearing loss or other health conditions
Limited older research suggests that taking vitamin B12 supplements may help with tinnitus symptoms in people with vitamin B12 deficiencies. However, further studies are necessary, and a person should not take any dietary supplements without first speaking with a doctor.
Healthcare professionals may recommend CBT, stress management techniques, and sound therapy to help manage tinnitus symptoms.
If a person finds that their current management techniques are not reducing their tinnitus symptoms, they should speak with their doctor about possible alternatives.
