How can you get vitamin D from the sun?
Sunlight does not contain any vitamin D -- or anything else -- right?
Is it like some kind of photosynthesis?
leave no stone unturned
lol, that was a nice break from TEB fever
Vitamin D is a prohormone, meaning that it has no hormone activity itself, but is converted to the active hormone 1,25-D through a tightly regulated synthesis mechanism. Production of vitamin D in nature always appears to require the presence of some UV light; even vitamin D in foodstuffs is ultimately derived from organisms, from mushrooms to animals, which are not able to synthesize it except through the action of sunlight at some point in the synthetic chain. For example, fish contain vitamin D only because they ultimately exist on calories from ocean algae which synthesize vitamin D in shallow waters from the action of solar UV.
Dont ask me for explanations, I just got curious from question and read it on wiki

We don't have to worry too much about getting too much Vitamin D from the sun here on the soggy West Coast, although this summer and fall were the sunniest on record in years. We usually don't get enough so have to purchase the pill form!! Some of the braver types hit the tanning salons!!
