Sunlight helps the human body to manufacture vitamin D. In that sense one can say that solar radiation contributes to vitamin D. It does not have vitamin D, though.
uv radiation destroys vitamin D
No UV light can not be treated as vit D precursor as it only provides the energy in the form of radiation for the reaction to take place. It is the steroid molecule present in dermis which is precursor for vitD synthesis.
Vitamin D has two forms which are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D without a subscript refers to either D2 or D3 or both.Vitamin D3 is produced in the skin of vertebrates after exposure to ultraviolet B light.
The term "vitamin D" refers to several different forms of this vitamin. ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D2 synthesized by plants. Vitamin D3 is synthesized by humans in the skin. D is the fourth letter in the Latin alphabet and the vitamin D was the fourth vitamin discovered.
Vitamin D is formed in the skin by the action of light on the skin, particularly ultra-violet light. Sunlight or a tanning bed will provide the necessary light. Sunlight shining through a window will work, but the window glass will absorb a lot of the necessary untraviolet radiation, so it will be a diminished effect.
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.

No, it does not produce vitamin D.
No, vitamin D is not from jade stone. Vitamin D is an animal product. Good food sources of vitamin D are milk, eggs, fish, beef, etc. We can also produce vitamin D in our skin when it is exposed to ultraviolet radiation (usually from the sun).

Vitamin D. It is produced in small quantities when the skin is exposed to natural sunlight and UV radiation.
No, melanin protects the skin from ultraviolet radiation. Vitamin D is synthesized in the skin and help with calcium absorption.
Vitamin D is produced in the skin, on exposure to UV (ultravoilet) radiation, from a modified cholesterol molecule; necessary for normal bone growth and function.
