Zim, I know you wrote the below some time ago, but I wanted to acknowledge what you said, again.
In particular, IMO, *HIGH* Vitamin D correlates strongly, almost perfectly, to *REDUCED* deaths, in particular. According to the graphs I've seen, from data taken around the world, if your vitamin D is ABOVE 50 NG/DL your risk of death is about ***ZERO*** ...and, as I recall, that is without regard to age or other co-morbidities.
I take 10,000 IU/day, except during summer, and I highly recommend everyone else, who can afford 25 cents/day, do the same as we go into this fall.
I'm not sure what is going to happen next. Maybe Covid is eventually going away, but it sure isn't acting like it got the message. Indeed, it seems to be spreading faster and faster, mutating and mutating, and Covid right now seems to me a lot like a hornet's nest that got kicked a few times too many.
I also think all should have supplemental zinc, at a minimum. If you take it in tablets, make sure you eat food first, so it doesn't upset your stomach. And quercetin (derived from apples) is a good ionophore to improve its uptake into cells, where it impedes viral replication. Or, you can do what I prefer, get a throat spray like Therazinc, sold on Amazon.
Perhaps elderberry syrup does the equivalent?
