Of the 26 who were treated without Vitamin D, 13 (half of them) were sent to the ICU (intensive care unit), where 2 of them unfortunately passed away.
However, in the group of Calcifediol-treated (this pretty much just means they were treated with Vitamin D) patients, only one(2%) of the 50 patients was admitted to ICU, and survived.
Now, does this mean that vitamin D is the answer to the Coronavirus and we should all gorge ourselves full of it? Most likely not. However, it does seem like vitamin D has some positive benefits for you.
