Claims for treatment
Clear Sound 911 is a “dietary supplement made from natural ingredients to restore hearing loss”[1].
What is the treatment?
Clear Sound 911 is a capsule which you take once a day.
The supplement claims to contain[1]:
Ashwagandha; Oat straw; Vitamin B1 (thiamine); Vitamin B2 (riboflavin); Gamma-aminobutyric acid (GABA); Rhodiola; Skullcap; Hawthorn; Chamomile; Potassium; Lutein; Lemon balm; Valerian; Bacopa monnieri; Magnolia; Magnesium; Biotin.
What are the downsides of this treatment?
Potential side effects from constituents[5] [6]. Cost – this supplement currently is on sale for $69.95 for one month’s supply excluding shipping and taxes.[1]
Has there been research into this treatment?
There have been no papers published on Clear Sound 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[2-15] [18-20], with the exception of magnesium[16].
Although some of the components are thought of as safe, some may be harmful, in particular ashwagandha[3], skullcap[11] (if Galerina autumnalis is the plant being referred to), Bacopa monnieri[13] and potassium[17] (if taken in large doses).
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.”[21]
No mention of supplements for the treatment of hearing loss are mentioned in the current NICE guideline for hearing loss[22].
Comments
There appears to be a lot of similarity between the marketing of this product and other products such as Sonus Complete and Tinnitus 911 – please see the relevant information sheets for details.
