Pretty comprehensive article.

I do D3 occasionally.

We work indoors. We live indoors. We mostly play indoors. We usually are wearing cloths. Fish isn’t the most common protein we consume.

I think it’s not hyperbole when vitamin D is stated as a common deficiency: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9573946/

We don’t run around naked outside all day anymore. Where are you supposed to get this from if you live/work/play indoors and wear cloths? Assuming you don’t wear sunblock or a hat, the face and neck (areas often exposed to the sun) account for a mere 5.5% of our skins surface area. To me, it’s no surprise that ~ 1 in 5 people are vitamin D deficient.

Not to mention in many parts of the US going outside without being covered adequately for much of the year will result in being very cold at best. Bits of you falling off and death at worse.

Where we currently live we get about four months of the year when we can get enough D from the sun alone.

I know the body does store it but not enough to keep you going eight months.

Also, there’s supposed to be a difference in vitamin D needs for bone health between the dark and the light pigmented:

I do a Walmart brand “Male over 50” one a day - it has about everything one needs including 125% of recommended D.
