Tinnitus 911 “offers long-term relief from ringing and buzzing ears”[1].

What is the treatment?

Tinnitus 911 is a capsule. The suggested use is 1 capsule taken twice daily.

What are the downsides of this treatment?

Has there been research into this treatment?

There have been no papers published on Tinnitus 911 as a supplement, but there have been a number published on its component parts.

What does the research say?

There is no evidence that any of the known components of this supplement are effective for treating tinnitus.[3-15]

Although some of the components are thought of as safe, some may be harmful including Vitamin B6 (if taken for prolonged periods)[3] and niacin
and green tea in large doses[4,14]. Buchu leaves should be avoided in pregnancy[11].

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.
