Zinc has been proselytized as the latest ''cure'' for covid.... along with vitamin D, vitamin C, and cow urine. Yup, cow urine. Now there's a treatment you're just racing to get your hands on. The fact is, there is no ''cure'' for this virus (because it hasn't been around long enough for us to have discovered one), nor is there a hard and fast proven treatment. Hell, we won't even have a vaccine until next year. Anyone proselytizing a ''cure'' is a carpetbagger selling snake oil.
Think of it this way: how long have we been trying to find a cure for the common cold (a coronavirus).... a long time, but the damn thing keeps mutating (fyi COLD is an acronym for chronic obstructive lung disease) . How long have we been trying to find a cure for influenza (a virus, not a corona virus)... again, a long time but the damn thing keeps mutating. How about HIV/AIDS? Herpes varieties? We haven't found ''cures'' for any of these known, been-around-forever, well researched, viruses, but we've found a ''cure'' for covid after only 4 short months???? And the cure is malaria drug? antibiotic? common vitamins? common mineral supplements? hot air from your hair dryer? cow urine? (and we've recently re-discovered that the earth is actually flat, and yes at the edge you do fall off and there is a sign saying ''here there be monsters'').
Pseudoscience and opinion have replaced medicine, science, and common sense. Just throw the latest ''cure'' at the ceiling and see what sticks. FFS!
The belief that [xyz] medication/vitamin/substance won't or can't hurt you is complete BS. Every substance, in the wrong dose or delivery method, or in conjunction with other medication/vitamin/substance, or in conjunction with other medical conditions, can cause illness, injury, or be fatal. You can actually overdose on zinc and vitamin C (that's not a challenge to try it BTW). You can also fatally OD on just plain water too.
