What is the name of the vitimin the sun gives us?

Im not sure though but from what i know. the sun is responsible for the production of vitamin D in our body. Most of the foods that we consumed are vitamin D precursor. Meaning it is inactive. But the vitamin D can only be active if we are exposed to the sun.

In addition. . . from what i read in one of the website(cant remember what the website was.). . it stated that "the healing rays of natural sunlight cannot penetrate through glass (e.g car's window) so not Vitamin D regenerated" . . this is a situation when you are in your car driving. .

I hope this could help you a bit. . 8 least you get an idea from what im saying here.
