As I mentioned at the beginning of the pandemic, one of the few supplements that work in warding off Covid is vitamin D. The Guardian just published an article mentioning several studies (in the UK, Spain and South Korea) that confirm that vitamin D deficiency is linked to a higher mortality rate. Among patients already infected, taking high doses of vitamin D significantly lowered the chances to be placed in intensive care or to die.
I long suspected that the reason why some countries like Denmark, Norway, Iceland or Finland have a much lower death rate is that most of the population was already used to taking vitamin D supplements due to the low sunlight in northern latitudes.
The death rate among Black people in the UK and the US is about 2.5 times higher than for White or East Asian people. Yet mortality appears to be relatively low in Africa itself. This can easily be explained by the fact that darker skin produces less vitamin D in higher latitudes. South Asian people in the UK have twice the death rate of Whites, not quite as much as people of African descent, but their skin tone is also intermediate.
