How does the skin make vitamin D and what limits its production?

Bronze Age Tanning&Salon | Olympia, WA | Frequently Aske...
Sun or UV light is the fuel that permits the body to manufacture vitamin D. But the amount of vitamin D formed in a given period of exposure depends on the color of your skin-that is, how rich your skin is in melanin. Melanin absorbs UV radiation. Therefore it diminishes the production of vitamin D. The darker a person's skin, the longer he or she has to be in the sun or exposed to UVB radiation to form a significant amount of vitamin D.

Can vitamin D be made with exposure of the skin to sunlight from a window?

Birth, pregnancy & breastfeeding related articles of interes...

Exposure of the skin to sunlight that has passed through plexiglas (Dupont Chemical Company, Memphis, TN, USA), most other plastics, or window pane glass (e.g., in buildings, motorized vehicles, covered strollers or prams, etc.) does not allow the endogenous production of vitamin D because these materials efficiently absorb ultraviolet B radiation (Holick 1994).
