African Americans in America have a low vitamin d on average due to their skin not picking up as much vitamin d in a more northern area like the united states

However it seems as if they don't get as many fractures as the white population and their immune defense isn't nessicarly bad or worse than the white population, which would be expected since they get less vitamin D.

I did read about how they are 3-4 more times likely to be diagnosed with schizhophrenia and stuff but I have no idea if that's because of vitamin d defiency or because of other socio econmic things or etc whatever


So my question is, are black people put at a disadvantage by living in areas with less sun due to the vitamin d defiencies or are they just doing fine? Because when I look at bone fractures by race and immune defense something they should be lacking in they don't

sorry if this post is structured bad or looks dumb I'm just trying to figure things out
