Claims for treatment

Zinc has a role in the auditory system so it has been suggested that it could reduce or eliminate the perception of tinnitus[1].

What is the treatment?

Zinc supplements are generally in the form of small tablets, but can be combined with other vitamins and minerals in tablets or capsules.

What are the downsides of this treatment?

High intakes of zinc can cause minor but unpleasant side effects. Zinc supplements can interact or interfere with some medicines.[2]

Has there been research into this treatment?

There have been a small number of studies conducted into the effect of zinc on tinnitus, and a systematic review[1].

What does the research say?

There is no evidence that the use of a zinc supplement improves symptoms in adults with tinnitus[1].

The evidence levels for zinc supplements as a treatment for tinnitus are low. We would suggest you talk to your GP before taking any new medication or supplement.

Current guidelines state that clinicians should not recommend zinc for treating patients with persistent, bothersome tinnitus[3] [4].

“Dietary supplements should not be recommended to treat tinnitus.”[5]
