Has there been research into this treatment?

Although there have been no papers published on Hear Complex as a supplement, there are a number of papers on the effects of its component parts.

What does the research say?

The limited evidence does not demonstrate that Ginkgo biloba is effective for tinnitus when this is the primary complaint. 4] It does not reduce the intensity of tinnitus or improve quality of life. [5]

There is no evidence that the use of vitamin B6 [6] or Vitamin A [7] improves symptoms in adults with tinnitus. Vitamin B6 and pre-formed Vitamin A can be harmful in large doses [6,8].

There is limited evidence that magnesium [9] may help tinnitus in people who are deficient in these elements.

There is no evidence that rhodiola is effective for tinnitus and there is limited evidence for its claimed therapeutic properties [10].

How high quality is the research?


Although independent evidence is limited, what there is does not show that the components of this supplement are effective for tinnitus. The
potential side effects may cause serious harm. We would suggest you talk to your GP before taking any new medication or supplement.

“Dietary supplements should not be recommended to treat tinnitus” [11]
