Then why does like half of america, have Vitamin D deficiency? 

If spending like a hour outsides in the sun everyday fixed the issue, then why are so many people still haveing deficiency?
Does half of the american population just not spend that much time outsides every day?

I dont know... sounds easier to just ask people to take a pill.

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".
