NAD+ Enhanced on Hearing Recovery in Sudden Sensorineural Hearing Loss: Randomized Controlled Trial
Study published October 2025. I myself started taking this supplement 4 months out from onset (so, a little late for me). I've since gained back ~15db in some high frequencies (not attributing that to this supplement, but who knows).
Anyway, leaving the study here in case any of you are in the thick of the acute phase of this terrible diagnosis
disclaimer: I'm not a doctor or anyone qualified to suggest supplements! I am not telling anyone they should take NAD+
Edits/additions: I don't directly attribute my late gains to NAD+, there are several other factors that go into recovery. Take note this was a SMALL study. Emphasize: I'm not at all qualified to tell people with ssnhl to take this or any other supplement.
