The makers claim

None made[1].

What is the treatment?

Calminax is a capsule taken once daily[1].

The ingredients of Calminax are listed as Ginkgo biloba extract, vitamin B6, vitamin B12, zinc and magnesium[1].

Other sites listing Calminax list different ingredients for this supplement.

What are the downsides of this treatment?

Potential side effects, allergic reactions and drug interactions from Ginkgo biloba2. Magnesium can cause minor but unpleasant side effects[3].

Cost – it is listed for £44.95 for 30 days supply[1].

Has there been research into this treatment?

Although there have been no papers published on Calminax 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 a zinc supplement[6] [7] or vitamin B6[8] improves symptoms in adults with tinnitus. Vitamin B6 can be harmful in large doses[8].

There is limited evidence that vitamin B12[9] and magnesium[10] may help tinnitus in people who are deficient in these elements.

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]
