Vitamin D is introduced through language and place in , under “COVID-era supplement debates.” The figure kept with that is 7. Do not line people up as better or worse. A population figure is not a cultural score. Fortified milk, fish and supplements backup sun-poor environments.

Because curiosity about bodies is valid — and unanswered curiosity is where race myths recruit. Only to explain mechanisms or public health. Averages never become league tables of worth.
No. Clinical decisions need clinicians, not atlas pages. By preferring review-level consensus and labeling open debates. A gradual change in trait frequency across geography, rather than a sharp racial border. Yes — dairying, malaria and altitude are classic feedback loops. See related diversity topics and the atlas page on genetic-distance myths.
Vitamin D begins as a skin precursor converted by UVB light, then activated in liver and kidney to a hormone regulating calcium and immune signaling. Darker pigmentation filters UV — an evolutionary trade-off in high-UV places — while low-UV latitudes, clothing and indoor work shift needs.
Say Vitamin D with , “COVID-era supplement debates,” and 7. The figure is not a grade of people.7
