Yeah.. 
I post a thread for this matter and people care about what I think, completely ignoring the facts that I've linked to in the OP. It's getting quite silly that we're arguing over something that is just facts as if I'd spread only rumors..Before you guys reply again, take only 3 minutes of your time to check this website out..: https://swprs.org/a-swiss-doctor-on-covid-19/
Good. We're on the same side, then. I like your info link. It has loads of info, and is pretty concise.
Just to toss out some extra info, one of the things that is recommended for high altitude sickness is vitamin B12. I think that people who have the symptoms of Covid, even if they don't have altitude problems, would be benefited by taking B12. And Methyl B12 seems to be a whole lot better than the simple vitamin.
I'm not certain, but I think Methyl B12 is the coenzyme of vitamin B12. Vitamin B12 is destroyed by the body as soon as the need for it is over. But coenzyme B12 stays in the body for up to 3 days as a backup, even if there isn't a need for it at the moment.
Lately it has been found that B12 is a brain enhancer.
