Evidence of harm



Evidence that it is not effective



The makers claim

The makers claim that Ottomax+ users notice “a significant reduction in the severity of their tinnitus.”[1]

What is the treatment?

Ottomax+ is a capsule which you take once a day[1].

The supplement claims to contain[1]:

Ginkgo biloba; magnesium; melatonin; vitamin B.

What are the downsides of this treatment?

Potential side effects from constituents[2-9].

Cost – this is not disclosed on the website[1].

Has there been research into this treatment?

There have been no papers published on Ottomax+ as a supplement, but there have been a number published on its component parts. Some of these relate to tinnitus.

What does the research say?

There is evidence that Ginkgo biloba is not effective for tinnitus[10] [11]. There is no evidence that any of the other components of this supplement are effective for treating tinnitus[2-9], with the exception of magnesium[12].

Although some of the components are thought of as safe, Ginkgo biloba and melatonin can interact negatively with other medication you may be taking[2] [4].

Although independent evidence is limited, what there is does not show that the components of this supplement are effective for tinnitus and that there may be risks involved in taking this supplement. We would suggest you talk to your GP before taking any new medication or supplement.

“Dietary supplements should not be recommended to treat tinnitus.”[13]
