Vitamin B12 is not a proven treatment for tinnitus. A small pilot study reported improvement in some participants who had low B12 and received injections. A larger placebo-controlled trial found no clear benefit for tinnitus without an identified cause.
If you’re concerned about a possible deficiency, ask a clinician whether testing makes sense for you. A confirmed deficiency deserves attention for your general health, and any change in ringing can be assessed separately. Read how to evaluate tinnitus supplement evidence.

What Did the Two Studies Find?
| Study | What the researchers reported |
|---|---|
| Pilot study with 40 participants with chronic tinnitus | The researchers reported improvement in tinnitus scores among B12-deficient participants who received B12 injections. This was a small subgroup, so the finding needs confirmation. |
| Placebo-controlled trial with 140 participants with idiopathic tinnitus | The researchers found no clear benefit of B12 for tinnitus severity. Idiopathic means the cause was unknown. |
The pilot study raises a question about people with documented low B12. It doesn’t establish that an over-the-counter tablet will produce the same result, or that people with adequate B12 levels will benefit. If a supplement advertisement cites the pilot study, check who improved, what they received, and how the researchers measured improvement.
When Is It Worth Asking About a B12 Test?
Tell your clinician if you’ve previously had low B12, eat very few foods that provide it, or have had digestive surgery that could affect absorption. Mention medicines you take regularly. Long-term use of metformin or some acid-reducing medicines can contribute to low B12.
Ringing by itself cannot tell you whether your B12 is low. If you’re also experiencing symptoms such as fatigue or tingling, mention them and let your clinician decide whether a blood test or another assessment would help. If you already take B12, tell them the dose and when you started. See what to tell your prescriber when tinnitus and medication changes overlap.

What if Your B12 Level Is Low?
Ask what may have caused the deficiency and how your clinician plans to treat it. The choice between tablets and injections can depend on why your B12 is low and how well you absorb it. Ask when to follow up and which symptoms to report.
If the ringing continues, describe it at your next appointment. For example, “I still hear the ringing at bedtime, and it takes me longer to fall asleep” gives the clinician a specific concern to address. If you also miss words in conversation or one ear seems quieter, mention that separately. See what happens during a hearing test.
When to Get the Ringing Checked
Arrange an assessment if tinnitus keeps returning, gets worse, or interferes with sleep or concentration. If it beats in time with your pulse, arrange an urgent medical appointment and mention the rhythm when you book. Read about pulsatile tinnitus.
If your hearing drops suddenly, seek medical care immediately, even if your ear feels blocked. Read about sudden hearing loss.
