I likewise take 50mg zinc daily, for the same reasons (immune system, antivirus, etc.).
My hearing is quite compromised from 60 years of playing loud (LOUD!) rock and roll in bands, from high-school garage bands, to large combos in noisy clubs, etc. Can't hear much above 2kHz, and have terrible loud tinnitus. So I have high-end DSP programmable hearing aids (Oticon "More") which are a life saver in conversations and noisy rooms.
I have no idea whether the daily zinc is helping or hurting my hearing, but I believe it's helping keep me healthy, so I intend to continue it.
Yep. All I know is Mr. GG2 and I haven’t had a sniffle since Nov 2022. We take the Zelenko protocol everyday and it keeps us healthy.
