Once your vitamin D levels are up, you can take the appropriate amounts per day to keep your levels at or above 50 ng/ml. I do a vitamin D test every 6 months just to make sure things are good. not too high or too low.

I also take NATURAL Vitamin-C every other day.

Zinc, ivermectin 12mg, iodine, and selenium once every 1-2 weeks.

Here's a snippet from this paper: "Our study confirms vitamin D deficiency to be a high-risk factor of severe COVID-19 disease and hospitalization, with 97% of our study’s patient cohort being vitamin D deficient, 55% of these being severely vitamin D deficient, and none had optimal levels.":

I never had the coof ever. I also eat raw broccolli, blueberries and garlic if that helps anything?

I never had to take HCQ or do nebulization but, I have a nebulizer with inhalable saline, just one of those, 1 drop of food grade hydrogen peroxide %3 and 1 lugol's drop of Iodine and inhale every hour until covid symptoms or gone. I have not tried this yet, hopefully I never have to do this, but I keep all of these supplies at home with me just in case.
