Re: Dad has very loud, high frequency tinnitus, sleeping very little.

Few things he can try to improve it:

Taurine (500mg-3g a day). It should help improve his tinnitus by some degree and get him relaxed so a double benefit here. One down side with taurine or a plus for some is the stimulation of gastric acid production so watch the dose and start with little.

Coffee is a complex one here it might prevent it but may aggravate it once you have it.

Others worth a try: Zinc. Omega 3. B12. Calcium.

Just research them and see. Hope your dad will improve. Tweet
