The more melanin a person has the less D their skin makes per same time of exposure. That explains the minority differences.

My wife's son is a doctor. He specifically told us to take D supplements, but not the kids.

That you are willing to even argue this is detrimental to society because you are obviously too stupid to know how stupid you are, which involves a lot of "I don't really know but I'll just spout off my misinformed opinions that could affect someone else's life."

Having low D levels indicates an immune system that is not functioning at its best.

You should excuse yourself from these conversions with an apology, but your ego probably can't do that, can it?

First of all, "my wife's son is a doctor" is not evidence.

Second, of all, your inflammatory tone is unwarranted and adds nothing of value.

It would be better if you actually looked at the sources and referenced those in your critique.

Of course, it would also be good if you didn't misconstrue my argument, e.g. I neither claimed that there are no vitamin D absorption differences between ethnicities, nor that low levels of vitamin D aren't a problem; low levels of any vital nutritional element are a problems. I did state that I haven't yet seen evidence of a direct link from increased (i.e. more than average) vitamin D intake to a lower probability of being infected with or being seriously affected by covid19.
