This is another long discarded bit of snake oil. If there were genuine home remedies for Covid that you could buy at the grocery store, we'd have told you about it. It turns out there are only two: vaccines and masks. It's healthy to have the recommended amount of Vitamin D, but not at the expense of a vaccine and a mask.

Im bored to death of Covid arguments, but I bet if you had to choose, healthy Vitamin D levels would be more effective than masks both for the individual and society.

Your bet is based on falsehoods, so it's quite fortunate you don't make these decisions for all of us. I'll take the other side of the bet any day.

Maybe. E.g. most Americans are still ignorant to the effect of obesity on severity, good advice would also include trying to lose a pounds a week, as it would be more effective than cloth masks once you catch it (which everyone will eventually, vaccinated or not)

I just don't understand how anyone could be against studies that basically say being deficient in an essential nutrient might lead to worse health outcomes.

Who is the “we” you speak for?

Yeah, you should have a well-rounded set of defenses. I don't think anyone is saying vitamin-D is a silver bullet.

Put a mask on and breathe on a pair of glasses.

Then please explain how the water molecules can pass through while other aerosols cannot.

Water particles aren't getting through. Please look up how condensation works, it's about a difference in temperatures.

Water particles absolutely are getting through. Yes the glasses are colder and breathe is warmer but it is still the water vapor from the hot moist breath that is the primary source of the water condensate.

While water particles do pass easily, viruses may not as respiratory aerosols are orders of magnitude larger about 1.6-5um vs. water at 0.27nm

Please look up the size of individual H2O molecules (which are what you exhale, not water drops).

It isn't the water molecules passing through the mask from your mouth. Your body is warmer than the air around you most of the year (unless you live in the tropics). It is mostly the heat of your breath passing through the mask, then hitting the cooler surface of the glasses, and making the moisture in the air that is already outside your mask condense on the glasses.
