Tinnitus Support Formulas

Blends built around ginkgo biloba and zinc, sometimes with B12 or magnesium. Cochrane reviews of both main ingredients found no reliable evidence of benefit for tinnitus, which makes this one of the clearer negatives in the catalogue.

Evidence last reviewed: August 2026

What the science says

  • Ginkgo biloba Moderate evidence

    A 2022 Cochrane review of ginkgo biloba for tinnitus found no evidence that it improves tinnitus in people whose primary complaint is tinnitus, with the available trials small and at risk of bias. The evidence points away from benefit rather than merely being absent.

  • Zinc Moderate evidence

    A Cochrane review of zinc supplementation for tinnitus found no evidence of improvement in tinnitus severity or loudness. Zinc is worth correcting only if you are genuinely deficient, which is uncommon.

  • Drug treatments generally Moderate evidence

    A network meta-analysis of randomised trials of pharmacologic treatment for tinnitus without a treatable cause found no agent with convincing efficacy. Sound therapy and cognitive behavioural therapy remain the interventions with actual support.

Dosage & safety

Studied doseBlends typically supply 120–240 mg of standardised ginkgo extract and 15–50 mg of zinc. Since neither has shown benefit, there is no evidence-based dose.
SafetyGinkgo increases bleeding risk and should be stopped before surgery and avoided with anticoagulants and antiplatelets; it may also lower the seizure threshold. Long-term zinc above about 40 mg/day causes copper deficiency, which can produce anaemia and neurological damage. New, one-sided or pulsatile tinnitus, or tinnitus with hearing loss or vertigo, needs medical assessment rather than a supplement.
