Where does it say half of Americans have deficiency?  I mean I could Google it but you could provide a news link.  Just seems way too high for me and I'm fucking high as a kite right now.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6075634/

Study from 2018.
found ~40% had deficiency of vitamin D.
39% of these people with deficiency where "Non-Hispanic African-Americans" (black) while they represent 16,5% of the population.
(ei. blacks make up disproportionate % of that) (same is true for Mexican-Americans, Hispanics ect) (lighter skin tone the less % you make up basically)

I've seen people quote 44%+, so I assume thats from a newer study.
Cant be arsed to look it up, but a large amount of people in the US have a vitamin D deficiency.

Enough for me to say "half".

Thanks for link now have to look up symptoms.  Only vitamin deficiency I know about is scurvy and that was like pirate days.
