There are quite a few other trials looking at similarly high doses tho, i.e. 100,000IU+10,000 per week: https://clinicaltrials.gov/ct2/show/NCT04483635?term=vitamin+d&cond=Covid19&draw=2&rank=5 … 10,000 per day for 3 days then 3,000 per day for 1 month:https://clinicaltrials.gov/ct2/show/NCT04536298?term=vitamin+d&cond=Covid19&draw=2&rank=2 …

Interesting that it almost seems they purposely used form & dosage to try to make sure it didn’t work - rather than use same form & dosage from the trial that had excellent results. Why not a large trial w/calcifediol in same dosages as Spanish trial??

While the trials were published months apart, they started recruiting within a few weeks of each other. The Spanish trial only published their results on 29 August, while the Brazilian study started on 2 June
