Adults who do not have regular, effective sun exposure year-round should consume at least 600 to 800 international units.

600 to 800 international units.
Per year?
Per day...... I take triple that. The bare minimum that I have read to minimize the severity of Covid is 2000-3000. Some people take more than that.
Vitamin D under 10000 a day causes no ill effects.
It is criminal that this has not been put out there by our public health authorities. It is inexplicable that doctors are not (on their own) recommending it to all of their patients.
The studies are very clear. Vitamin D may be the easiest and least controversial remedy to prevent severe Covid. Cheap and effective yet they are not pushing it?
Criminal.
Per day........... or hour..................
A better choice is 10,000 units per day during winter and covid season
