Studies highlight potential life-saving benefits. But some experts aren’t convinced.

But among the 50 people who received the vitamin D treatment on top of standard care, only one person ended up in the ICU. None died.
In their study write-up, published in October in the Journal of Steroid Biochemistry and Molecular Biology, the Spanish researchers explained that their experiment was a “pilot” study that requires follow-up work.
