Vitamin D3
Zinc
Elderberry
K2
Ivermectin
Stocked up on all those and got through Covid with minor hassle. Never got in my lungs. All good.
I had been prescribed an antidepressant as well but only took that one day. Didn’t like the way it made me feel and you have to avoid caffeine. Didn’t feel like I needed it.
I also megadosed on Vitamin C. But I usually do that this time of year.
I also have super-immunity having had Covid-19 early on and still carry the antibodies for it, I'm checked every 6-8 weeks for them via blood draw.
With all that, I was exposed to Delta at least 4x, never caught it.
I've been exposed to Omicron more times than I can recall now and never caught that either. I spent the weekend with my GF on a local ski trip, right at the point she was most infections with it. Still, didn't catch Omicron.
One of the men in my weekly bible study had it, all 12 of us were in a closed room with him for several hours during a study of Matthew. I didn't catch it, several others did.
I'm either super lucky (ha, right) or the above supplements along with my immunity WORKS. I think they work.
I'm also immune system suppressed due to a genetic condition I have, so I have to be careful about being exposed to the virus. The thing with the Omicron variant, it's a sneaky little bastard and it infects as many as it can. If I was going to catch it, I'd have caught it by now. More proof that supplementing Vitamin D and the rest I cited above works as a mitigation strategy.
Just my own opinion of course.
