Very interesting! What dosage did you take? Do you notice further improvements until now?
I take 250 mg. per day, divided into 125 mg. in the morning and again in the evening. My hearing has continued to improve. It started with very faint sounds, and now I estimate that my hearing is about 50% of normal after about 10 months of taking NR. Unfortunately I haven't noticed any improvement to my tinnitus, but I'm still hopeful that eventually my brain will react to the changes.
NR is pretty amazing. It has also dramatically reduced the frequency of my migraines, and the auras are pretty much gone. It also eliminated some minor nerve pain as well as pre-cancerous lesions on my skin. I'm giving NR to a pet parrot that has had fatty liver disease all her life, and it appears to be reversing that as well.
Disclaimer: I was so impressed that I bought shares of the company that owns the patent on the NR that is being sold commercially.
