Vitamin D Absorbtion, Location, and Skin Color

Apparently, my ancestors were from Greenland…
(And a reminder that most of us are probably low on vitamin D.)

The twin role played by the skin – protection from excessive UV radiation and absorption of enough sunlight to trigger the production of vitamin D – means that people living in the lower latitudes, close to the Equator, with intense UV radiation, have developed darker skin to protect them from the damaging effects of UV radiation. In contrast, those living in the higher latitudes, closer to the Poles, have developed fair skin to maximize vitamin D production.
