Vitamin D supplements protect against Covid-19 to an extent which would make a manufacturer of Covid-19 vaccines more than satisfied. According to an Italian meta-study, vitamin D supplementation reduces the chance of ICU admission and the chance of mortality by tens of percent.

Vitamin D supplements protect against Covid-19 to an extent that manufacturers of Covid-19 vaccines would be more than satisfied. According to an Italian meta-study, vitamin D supplementation reduces the chance of ICU admission and the chance of mortality by tens of percent.

Study

Italian doctors, affiliated with the Arnas Ospedali Civico Di Cristina, traced 5 previously published studies in the scientific literature in which subjects with Covid-19 had received vitamin D. The studies compared the course of the disease in this group with the course of the disease in subjects who did not take vitamin D supplements.

The subjects in the experimental group received vitamin D in doses of a few thousand to tens of thousands of IEs per day. The supplementation period lasted 14-30 days.

Results
The figures below are reduced in size. Click on them for a larger version. They tell that supplementing with vitamin D reduced the risk of admission to an intensive care unit [ICU] by 70 percent and the risk of death by 50 percent.

Not all studies were equally reliable. There was even one whose reliability the Italians described as 'high risk of bias'. This was the study by Torres (2022), who incidentally reported the least promising results.

Weird, isn't it?
Remarkably, this meta-study conducted by Italians used studies conducted in Spain, Saudi Arabia and Brazil. Hospitals and universities in other countries are apparently not interested in the question of whether you can reduce human suffering with dirt-cheap supplements during a pandemic.
