> Ivermectin for example also has only equivocal evidence for its use well it was actually pretty promising in some countries data early on. the problem is when you extrapolate that data to the world at large you have problems with populations. so yes, ivermectin is useful in areas that have parasites that can cause the host to die from when in a weakened state due to the immunosupressing drugs that they give to stop the cytokine storms that kill covid patients, exactly the populations that the data showed a benefit from and also standard course in those countries. when done in places without a high risk of secondary parasitic infection the data was that it was not useful. There were/are some studies done now because it's so cheap but it's not really all that effective outside of it being an secondary treatment in those parasitic prone countries. But since it showed promise there the antivaxxers were hell bent on using it regardless of the why because it wasn't a vaccine and here we are. Too much vitamin D is bad too and you definitely don't want that and without data supporting it being highly effective against covid it's not useful as a prophylactic. That said, vitamin D is generally correlated with a better immune system response against respiratory illness. supplementing a reasonable amount is not usually considered harmful but it's wise to talk to a doctor.
