Guideline Recommendations on Dietary Supplements and Alternative Therapies for Persistent Tinnitus

Recommendation Against Dietary Supplements

The American Academy of Otolaryngology‑Head and Neck Surgery (AAO‑HNS) advises that clinicians should not recommend any dietary supplement (e.g., Ginkgo biloba, melatonin, zinc) for patients with persistent, bothersome tinnitus. 1, 2, 3
The 2014 AAO‑HNS clinical practice guideline issues a formal recommendation against the use of dietary supplements, citing evidence from randomized trials and systematic reviews that raised methodological concerns. 1

The guideline rates the supporting evidence as Grade B‑C, reflecting studies with methodological flaws, bias, and insufficient statistical power. 2
The benefit‑harm balance favors avoiding supplements because the potential benefit of preventing ineffective treatment outweighs any unproven advantage. 3
Over‑the‑counter supplements are not regulated by the FDA, leading to variable active‑ingredient content and uncertain dosing, which adds safety concerns. 4

Avoiding unproven supplements prevents unnecessary health‑care costs for patients. 2
It prevents false hope in patients with chronic tinnitus. 3
It reduces the risk of potential adverse effects associated with uncontrolled supplement use. 5
Resources can be redirected toward therapies with solid evidence of efficacy. 1

Cognitive‑behavioral therapy (CBT) should be offered to patients with persistent, bothersome tinnitus; RCTs demonstrate a clear benefit that outweighs harms. Evidence strength: high‑quality RCTs. 3, 6
Hearing‑aid evaluation is recommended for patients who have any degree of hearing loss together with tinnitus, including mild loss, to improve auditory input and tinnitus perception. Evidence strength: moderate‑quality studies. 1, 6
Sound therapy may be employed as an adjunct for persistent tinnitus, with supportive trial data indicating benefit. Evidence strength: moderate. 3, 6
Patient education and counseling are essential components of management, helping patients adopt coping strategies and understand realistic expectations. Evidence strength: consensus‑based. 6, 7

Antidepressants, anticonvulsants, and anxiolytics should not be used as primary treatments for tinnitus because evidence does not support routine benefit. 3, 5
Intratympanic pharmacologic interventions lack sufficient evidence for routine recommendation. 5
Transcranial magnetic stimulation (TMS) is not recommended for routine use in tinnitus management due to limited and inconsistent data. 2, 5

Do not equate commercial availability of a supplement with proven efficacy; many products lack rigorous testing. 2
The variability in composition of over‑the‑counter supplements poses an additional safety risk. 4
Certain medications, such as antidepressants, can exacerbate tinnitus in some patients. 3, 5
Although many methodologically weak studies reported modest benefits, these do not justify routine supplement use given potential harm and cost. 1
