i am sorry to hear that you have tinnitus but sadly, I have not heard of Vitamins, B or otherwise, providing tinnitus relief. I had a sudden sensorineural hearing loss (SSHL) in February 1990 (likely from a virus, nothing to do with diabetes), and am profoundly deaf in only the left ear with severe tinnitus ever since. I have been to tinnitus experts around the country, and now check in every five years or so on the latest tinnitus treatments. Retraining therapy holds promise for some with milder levels of loss, but not so much when it was a complete hearing loss. It didnt help me, nor will hearing aids, because my good ear is now better than perfect.

I also suggest you use the ATA as a resource, and consider their approved treatment options. https://www.ata.org/managing-your-t...eatment-options They can also direct you to a specialist in your area.
