Can vitamin B‑complex supplementation be used to treat tinnitus, and what assessment and dosing are recommended?

Vitamin B Complex Should NOT Be Recommended for Tinnitus Treatment

Clinicians should not recommend vitamin B complex supplementation for treating patients with persistent, bothersome tinnitus. This recommendation is based on the 2014 American Academy of Otolaryngology-Head and Neck Surgery clinical practice guideline, which explicitly advises against dietary supplements including vitamins for tinnitus management 1.

Evidence-Based Rationale

The guideline's Statement 11 on dietary supplements provides a clear directive: avoid recommending Ginkgo biloba, melatonin, zinc, or other dietary supplements (which encompasses vitamin B complex) for persistent, bothersome tinnitus 1. This recommendation is:

• Grade B evidence quality (based on RCTs and systematic reviews)
• Preponderance of benefit over harm (benefit of avoiding unproven therapy outweighs potential benefit)
• Designed to avoid unproven therapy, false hope, unnecessary expense, and potential side effects 1

Conflicting Research Evidence

While the guideline is definitive, some individual studies show mixed results:

Studies suggesting potential benefit:

• A 2018 observational study found 28% of patients with tinnitus-only (no hearing loss) showed subjective and objective improvement with vitamin B complex supplementation 2
• A 1998 study using multi-drug treatment (including vitamin B complex with betahistine and diazepam) reported 54% felt treatment was effective, though this was not a controlled trial and cannot isolate vitamin B's effect 3

Studies showing no benefit:

• A 2024 double-blind RCT of 140 patients found no significant difference in tinnitus severity (VAS or THI scores) between vitamin B12 and placebo groups at 1 and 3 months 4
• A 2013 study of 100 patients found vitamin B12 replacement was not effective for tinnitus, with no significant improvement on VAS scores 5

Clinical Algorithm

For patients requesting vitamin B complex for tinnitus:

1. Explain the lack of evidence - No high-quality studies support routine use
2. Screen for vitamin B12 deficiency if risk factors present (vegetarian diet, malabsorption, elderly, metformin use)
3. If deficiency confirmed - Treat the deficiency for its own sake, but do not promise tinnitus improvement
4. Redirect to evidence-based interventions:
   • Hearing aid evaluation if hearing loss present 1
   • Cognitive-behavioral therapy (strongest recommendation) 1
   • Sound therapy as an option 1
   • Education and counseling about management strategies 1

Important Caveats

• The 2018 study 2 suggests a possible subgroup (tinnitus without hearing loss) might benefit, but this requires validation in controlled trials before clinical adoption
• Vitamin B complex is generally safe, but recommending it diverts patients from proven therapies and creates false expectations
• The most recent 2025 VA/DOD guideline 6 emphasizes gaps in knowledge and the need for evidence-based approaches, reinforcing caution with unproven supplements

Bottom line: Prioritize CBT, hearing aids (if hearing loss present), and sound therapy over vitamin supplementation. Only treat documented vitamin B deficiency for its own medical indication, not as a tinnitus treatment.
